        System for Cross-Domain Identity Management: Core Schema
                     draft-ietf-scim-core-schema-19

Abstract

   The System for Cross-Domain Identity Management (SCIM) specifications
   are designed to make identity management in cloud based applications
   and services easier.  The specification suite builds upon experience
   with existing schemas and deployments, placing specific emphasis on
   simplicity of development and integration, while applying existing
   authentication, authorization, and privacy models.  Its intent is to
   reduce the cost and complexity of user management operations by
   providing a common user schema and extension model, as well as
   binding documents to provide patterns for exchanging this schema
   using HTTP protocol.

   This document provides a platform neutral schema and extension model
   for representing users and groups and other resource types in JSON
   format.  This schema is intended for exchange and use with cloud
   service providers.

1.  Introduction and Overview

   While there are existing standards for describing and exchanging user
   information, many of these standards can be difficult to implement
   and/or use; e.g., their wire protocols do not easily traverse
   firewalls and/or are not easily layered onto existing web protocols.
   As a result, many cloud providers implement non-standardized
   protocols for managing users within their services.  This increases
   both the cost and complexity associated with organizations adopting
   products and services from multiple cloud providers as they must
   perform redundant integration development.  Similarly, cloud services
   providers seeking to inter-operate with multiple application
   marketplaces or cloud identity providers would require pairwise
   integration.

   SCIM seeks to simplify this problem through a simple to implement
   specification suite that provides a common user schema and extension
   model, as well as a SCIM Protocol document, that defines exchanging
   this schema via an HTTP based protocol [I-D.ietf-scim-api].  [[RFC
   Editor: This document an the companion scim-api document should be

   published together]] It draws inspiration and best practice, building
   upon existing user protocols and schemas from a wide variety of
   sources including, but not limited to, existing services exposed by
   cloud providers, PortableContacts [PortableContacts], vCards
   [RFC6350], and Lightweight Directory Access Protocol (LDAP) directory
   services [RFC4512].

   SCIM protocol is an application-level protocol for provisioning and
   managing identity data specified through SCIM schemas.  The protocol
   supports creation, modification, retrieval, and discovery of core
   identity resources such as Users and Groups, using a subset of the
   HTTP methods (GET for retrieval of resources, POST for creation,
   searching and bulk modification, PUT for attribute replacement within
   resources, PATCH for partial update of attributes, and DELETE for
   removing resources).

   This document provides a JSON based schema and extension model for
   representing users and groups, as well as service provider
   configuration.  This schema is intended for exchange and use with
   cloud service providers and other cross-domain scenarios.

1.1.  Requirements Notation and Conventions

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
   document are to be interpreted as described in [RFC2119].

   Throughout this document, values are quoted to indicate that they are
   to be taken literally.  When using these values in protocol messages,
   the quotes MUST NOT be used as part of the value.

   Throughout this documents all figures MAY contain spaces and extra
   line-wrapping for readability and space reasons.  Similarly, some
   URI's contained within examples, have been shortened for space and
   readability reasons.

1.2.  Definitions

   Service Provider
      An HTTP web application that provides identity information via the
      SCIM protocol.

   Client
      A website or application that uses the SCIM protocol to manage
      identity data maintained by the service provider.  The client
      initiates SCIM HTTP requests to a target service provider.

   Provisioning Domain



Hunt, et al.            Expires November 12, 2015               [Page 4]


Internet-Draft           draft-scim-core-schema                 May 2015


      A provisioning domain is an administrative domain external to the
      domain of a service provider for legal or technical reasons.  For
      example, a SCIM client in an enterprise (provisioning client)
      communicates with a SCIM service provider that is owned or
      controlled by a different legal entity.

   Resource Type
      A type of a resource that is managed by a service provider.  The
      resource type defines the resource name, endpoint URL, Schemas,
      and other meta-data which indicate where a resource is managed and
      how it is composed; e.g., "User" or "Group".

   Resource
      A service provider managed artifact containing one or more
      attributes.  For example a "User" or "Group".

   Endpoint
      An endpoint for a service provider is a defined base path relative
      to the service providers Base URI (see definitions of
      [I-D.ietf-scim-api]) over which SCIM operations MAY be performed
      against SCIM resources.  For example, assuming the service
      provider Base URI is "https://example.com/": "User" resources may
      be accessed at the "https://example.com/Users", or
      "https://example.com/v2/Users" (when including protocol version,
      see Section 3.13 [I-D.ietf-scim-api]) endpoint.  Service provider
      schemas MAY be returned from the "/Schemas" endpoint.

   Schema
      A collection of attribute definitions that describe the contents
      of an entire or partial resource; e.g.,
      "urn:ietf:params:scim:schemas:core:2.0:User".  The attribute
      definitions define the name of the attribute, and metadata such as
      type (e.g., string, binary), cardinality (singular, multi,
      complex), mutability, and returnability.

   Singular Attribute
      A resource attribute that contains 0..1 values; e.g.,
      "displayName".

   Multi-valued Attribute
      A resource attribute that contains 0..n values; e.g., "emails".

   Simple Attribute
      A singular or multi-valued attribute whose value is a primitive;
      e.g., "String".  A simple attribute MAY not contain sub-
      attributes.

   Complex Attribute



Hunt, et al.            Expires November 12, 2015               [Page 5]


Internet-Draft           draft-scim-core-schema                 May 2015


      A singular or multi-valued attribute whose value is a composition
      of one or more simple attributes; e.g., "addresses" has the sub-
      attributes "streetAddress", "locality", "postalCode", and
      "country".

   Sub-Attribute
      A simple attribute that is contained within a complex attribute.

2.  SCIM Schema

   A SCIM server provides a set of resources, the allowable contents of
   which are defined by a set of schema URIs and a resource type.
   SCIM's schema is not a document-centric one such as with
   [XML-Schema].  Instead, SCIM's support of schema is attribute based
   where each attribute may have different type, mutability,
   cardinality, or returnability. validation of documents and messages
   is always performed, as specified by the SCIM specifications by an
   intended receiver.  Validation is performed by the receiver in the
   context of a SCIM protocol request (see [I-D.ietf-scim-api]).  For
   example, a SCIM service provider, upon receiving a request to replace
   an existing resource with a replacement JSON object, evaluates each
   asserted attribute based on its characteristics as defined in the
   relevant schema (e.g., mutability) and decides which attributes may
   be replaced or ignored.

   This specification provides a minimal core schema for representing
   users and groups (resources), encompassing common attributes found in
   many existing deployments and schemas.  In addition to the minimal
   core schema, this document also specifies a standardized means by
   which service providers may extend schemas to define new resources
   and attributes in both standardized and service provider specific
   cases.

   Resources are categorized into common resource types such as "User"
   or "Group").  Collections of resources of the same type are usually
   contained within the same "container" ("folder") endpoint.

2.1.  Attributes

   A resource is a collection of attributes identified by one or more
   schemas.  Minimally, an attribute consists of the attribute name and
   at least one simple or complex value either of which may be multi-
   valued.  For each attribute, SCIM schema defines the data type,
   plurality, mutability, and other distinguishing features of an
   attribute.






Hunt, et al.            Expires November 12, 2015               [Page 6]


Internet-Draft           draft-scim-core-schema                 May 2015


   Attribute names are case-insensitive and MAY be camel-cased (e.g.,
   "camelCase").  SCIM resources are represented in JSON [RFC7159] and
   MUST specify schema via the "schemas" attribute per Section 3.

   Attribute names MUST conform to the following ABNF rules:

               ATTRNAME   = ALPHA *(nameChar)
               nameChar   = "$" / "-" / "_" / DIGIT / ALPHA

                    Figure 1: ABNF for Attribute Names

   The above rules (and other rules in this specification) use the "Core
   Rules" from ABNF, see Appendix B [RFC5234].  Unless otherwise
   specified in this specification, all ABNF strings are case
   insensitive and the character set for these strings is US-ASCII.  For
   example, all attribute names defined by the above rule are case
   insensitive.

   When defining attribute names it should be noted that the hyphen
   ("-") is not permitted in Javascript (and some other languages)
   attribute names.  While there are no known issues within HTTP
   protocol and JSON notation, attribute names containing hyphens MAY
   need to be escaped when declaring corresponding names of Javascript
   attributes.

2.2.  Attribute Characteristics

   If not otherwise stated in Section 7, SCIM attributes have the
   following characteristics:

   o  are OPTIONAL (is not REQUIRED).

   o  are case insensitive ("caseExact" is "false"),

   o  are modifiable ("mutability" is "readWrite"),

   o  are returned in response to queries (returned by default),

   o  have no canonical values (for example, the "type" sub-attribute in
      Section 2.4,

   o  are not unique ("uniqueness" is "none"), and,

   o  of type string (Section 2.3.1).

2.3.  Attribute Data Types

   Attribute data types are derived from JSON [RFC7159].  The JSON
   format defines a limited set of data types, hence, where appropriate,
   alternate JSON representations derived from XML Schema [XML-Schema]
   are defined below.  SCIM extensions SHOULD NOT introduce new data
   types.

   The following is a table that maps the following data types, to SCIM
   schema type and the underlying JSON data type:

   +--------------+-----------------+----------------------------------+
   | SCIM Data    | SCIM Schema     | JSON Type                        |
   | Type         | "type"          |                                  |
   +--------------+-----------------+----------------------------------+
   | String       | "string"        | String per Sec. 7 [RFC7159]      |
   | Boolean      | "boolean"       | Value per Sec. 3 [RFC7159]       |
   | Decimal      | "decimal"       | Number per Sec. 6 [RFC7159]      |
   | Integer      | "integer"       | Number per Sec. 6 [RFC7159]      |
   | DateTime     | "dateTime"      | String per Sec. 7 [RFC7159]      |
   | Binary       | "binary"        | Base64 encoded String per Sec. 7 |
   |              |                 | [RFC7159]                        |
   | Reference    | "reference"     | String per Sec. 7 [RFC7159]      |
   | Complex      | "complex"       | Object per Sec. 4 [RFC7159]      |
   +--------------+-----------------+----------------------------------+

              Table 1: SCIM Data Type to JSON Representation

2.3.1.  String

   A sequence of zero or more Unicode characters encoded using UTF-8 as
   per [RFC2277] and [RFC3629].  The JSON format is defined in Section 7
   [RFC7159].  A "String" attribute MAY specify a required data format.
   Additionally, when "canonicalValues" is specified, service providers
   MAY restrict accepted values to the specified values.

2.3.2.  Boolean

   The literal "true" or "false".  The JSON format is defined in
   Section 3 [RFC7159].  A boolean has no case sensitivity or
   uniqueness.

2.3.3.  Decimal

   A real number with at least one digit to the left and right of the
   period.  The JSON format is defined in Section 6 [RFC7159].  A
   decimal has no case sensitivity.

2.3.4.  Integer

   A decimal number with no fractional digits.  The JSON format is
   defined in Section 6 [RFC7159] with the additional constraint that
   the value MUST NOT contain fractional or exponent parts.  An integer
   has no case sensitivity.

2.3.5.  DateTime

   A DateTime value (e.g., 2008-01-23T04:56:22Z).  The attribute value
   MUST be encoded as a valid xsd:dateTime as specified in Section 3.3.7
   [XML-Schema].  A date-time has no case-sensitivity or uniqueness.

   Values represented in JSON MUST conform to the XML constraints above
   and are represented as a JSON String per Section 7 [RFC7159].

2.3.6.  Binary

   Arbitrary binary data.  The attribute value MUST be encoded in base
   64 encoding as specified in Section 4 [RFC4648].  In cases where a
   URL-safe encoding is required, the attribute definition MAY specify
   Base 64 URL encoding be used as per Section 5 [RFC4648].  Unless
   otherwise specified in the attribute definition, trailing padding
   characters MAY be omitted ("=").

   In JSON representation, the encoded values are represented as a JSON
   String per Section 7 [RFC7159].  A binary is case-exact and has no
   uniqueness.

2.3.7.  Reference

   The value is a URI for a resource.  A resource MAY be a SCIM
   resource, an external link to a resource (e.g., a photo), or it may
   be an identifier such as a URN.  The value MUST be the absolute or
   relative URI of the target resource.  Relative URIs should be
   resolved as specified in Section 5.2 [RFC3986].  However, the base
   URI for relative URI resolution MUST include all URI components and
   path segments up to but not including the Endpoint URI (the SCIM
   service provider root endpoint); e.g., the base URI for a request to
   "https://example.com/v2/Users/2819c223-7f76-453a-919d-413861904646"
   would be "https://example.com/v2/" and the relative URI for this
   resource would be "Users/2819c223-7f76-453a-919d-413861904646".

   In JSON representation, the URI value is represented as a JSON String
   per Section 7 [RFC7159].  A reference is case-exact.  A reference has
   a "referenceType" that indicates what types of resources may be
   linked as per Section 7.

   Performing a GET operation on a reference URI MUST return the target
   resource or an appropriate HTTP response code.  The service provider
   MAY optionally choose to enforce referential integrity for reference
   types referring to SCIM resources.

   By convention, a reference is commonly represented as a "$ref" sub-
   attribute in complex or multi-valued attributes, however this is
   OPTIONAL.

2.3.8.  Complex

   A singular or multi-valued attribute whose value is a composition of
   one or more simple attributes.  The JSON format is defined in
   Section 4 [RFC7159].  The order of the component attributes is not
   significant.  Servers and clients MUST NOT require or expect
   attributes to be in any specific order when an object is either
   generated or analyzed.  A complex attribute has no uniqueness or case
   sensitivity.  A complex attribute MUST NOT contain sub-attributes
   that have sub-attributes (i.e., that are complex).

2.4.  Multi-valued Attributes

   Multi-valued attributes contain a list of elements using the JSON
   array format defined in Section 5 of [RFC7159].  Elements can be
   either

   o  primitive values, or

   o  objects with a set of sub-attributes and values, using the JSON
      object format defined in Section 4 of [RFC7159], in which case
      they MAY also be considered to be complex attributes.  As with
      complex attributes, the order of sub-attributes is not
      significant.  The pre-defined sub-attributes listed in this
      section can be used with multi-valued attribute objects but these
      sub-attributes MUST be used with the meanings defined here.

   The pre-defined set of sub-attributes for a multi-valued attribute
   are:

   type
      A label indicating the attribute's function; e.g., "work" or
      "home".

   primary
      A Boolean value indicating the 'primary' or preferred attribute
      value for this attribute, e.g., the preferred mailing address or
      the primary e-mail address.  The primary attribute value "true"

Internet-Draft           draft-scim-core-schema                 May 2015


      MUST appear no more than once.  If not specified, the value of
      "primary" SHALL be assumed to be "false".

   display
      A human readable name, primarily used for display purposes and has
      a mutability of "immutable".

   value
      The attribute's significant value; e.g., the e-mail address, phone
      number, etc.

   $ref
      The reference URI of a target resource, if the attribute is a
      reference.  URIs are canonicalized per Section 6.2 of [RFC3986].
      While the representation of a resource MAY vary in different SCIM
      protocol API versions (see section 3.13 of [I-D.ietf-scim-api]),
      URI's for SCIM resources with an API version SHALL be considered
      comparable to one without a version or different version.  For
      example, "https://example.com/Users/12345" is equivalent to
      "https://example.com/v2/Users/12345".



   When returning multi-valued attributes, service providers SHOULD
   canonicalize the value returned (e.g., by returning a value for the
   sub-attribute "type" such as "home" or "work") when appropriate
   (e.g., for e-mail addresses and URLs).

   Service providers MAY return element objects with the same "value"
   sub-attribute more than once with a different "type" sub-attribute
   (e.g., the same e-mail address may used for work and home), but
   SHOULD NOT return the same (type, value) combination more than once
   per attribute, as this complicates processing by the consumer.

   When defining schema for multi-valued attributes, it is considered a
   good practice to provide a type attribute that MAY be used for the
   purpose of canonicalization of values.  Further, in the schema
   definition for an attribute MAY define the recommended canonical
   values (see Section 7).

2.5.  Unassigned and Null Values

   Unassigned attributes, the null value, or empty array (in the case of
   a multi-valued attribute) SHALL be considered to be equivalent in
   "state".  Assigning an attribute with the value "null" or an empty
   array (in the case of multi-valued attributes) has the effect of
   making the attribute "unassigned".  When a resource is expressed in

   JSON form, unassigned attributes, though they are defined in schema,
   MAY be omitted for compactness.

3.  SCIM Resources

   Each SCIM resource is a JSON object that has the following
   components:

   Resource Type
      Each resource (or JSON object) in SCIM has a resource type
      ("meta.resourceType", see Section 3.1) that defines the resource's
      core attribute schema and any attribute extension schema as well
      as the endpoint where objects of the same type may be found.  More
      information about a resource MAY be found in its resourceType
      definition (see Section 6).

   Schemas Attribute
      The "schemas" attribute is a REQUIRED attribute that MUST be
      present and is an array of Strings containing URIs which are used
      to indicate the namespaces of the SCIM schemas that define the
      attributes present in the current JSON structure.  It may be used
      by parsers to define the attributes present in the JSON structure
      that is the body to an HTTP Request or Response.  Each String
      value must be a unique URI.  All representations of SCIM schemas
      MUST include a non-empty array with value(s) of the URIs supported
      by that representation.  The schemas attribute for a resource MUST
      only contain values defined as "schema" and "schemaExtensions" for
      the resource's "resourceType".  Duplicate values MUST NOT be
      included.  Value order is not specified and MUST NOT impact
      behavior.

   Common Attributes
      Are attributes that are part of every SCIM resource regardless of
      the value of the "schemas" attribute present in a JSON body.
      These attributes are not defined in any particular schema, but
      SHALL be assumed to be present in every resource regardless of the
      value of the "schemas" attribute.  See Section 3.1.

   Core Attributes
      A resource's core attributes are those attributes that sit at the
      top level of the JSON object together with the common attributes
      (such as the resource "id").  The list of valid attributes is
      specified by the resource's resource type "schema" attribute (see
      Section 6).  This same value is also present in the resource's
      "schemas" attribute.

   Extended Attributes

      Extended schema attributes are specified by the resource's
      resource type "schemaExtensions" attribute (see Section 6).
      Unlike core attributes, extended attributes are kept in their own
      sub-attribute namespace identified by the schema extension URI.
      This avoids attribute name conflicts that may arise due to
      conflicts from separate schema extensions.

   The following example "User" contains the common attributes "id",

   attributes "userName", "name", as well as extended enterprise user
   attributes "employeeNumber" and "costCenter" which are contained in
   their own JSON sub-structure identified by their schema URI.  Some

3.1.  Common Attributes

   Each SCIM resource (Users, Groups, etc.) includes the following
   common attributes.  With the exception of "ServiceProviderConfig" and
   "ResourceType" server discovery endpoints and their associated
   resources, these attributes MUST be defined for all resources,
   including any extended resource types.  When accepted by a service
   provider (e.g., after a SCIM create), the attributes "id" and "meta"
   (and its associated sub-attributes) MUST be assigned values by the
   service provider.  Common attributes are considered to be part of
   every base resource schema and do not use their own schemas URI and
   SHALL NOT be considered schema extensions.

   For backwards compatibility reasons, some existing schema MAY list
   common attributes as part of the schema.  The attribute
   characteristics listed here SHALL take precedence.

   id
      A unique identifier for a SCIM resource as defined by the service
      provider.  Each representation of the resource MUST include a non-
      empty "id" value.  This identifier MUST be unique across the SCIM
      service provider's entire set of resources.  It MUST be a stable,
      non-reassignable identifier that does not change when the same
      resource is returned in subsequent requests.  The value of the
      "id" attribute is always issued by the service provider and MUST
      NOT be specified by the client.  The string "bulkId" is a reserved
      keyword and MUST NOT be used within any unique identifier value.
      The attribute characteristics are "caseExact" as "true" and a
      mutability of "readOnly".  See Section 9 for additional
      considerations regarding privacy.

   externalId
      A String that is an identifier for the resource as defined by the
      provisioning client.  The "externalId" may simplify identification
      of a resource between the provisioning client and the service
      provider by allowing the client to use a filter to locate the
      resource with an identifier from the provisioning domain,
      obviating the need to store a local mapping between the
      provisioning domain's identifier of the resource and the
      identifier used by the service provider.  Each resource MAY
      include a non-empty "externalId" value.  The value of the
      "externalId" attribute is always issued by the provisioning client
      and MUST NOT be specified by the service provider.  The service
      provider MUST always interpret the externalId as scoped to the
      provisioning domain.  While the server does not enforce
      uniqueness, it is assumed that the value's uniqueness is
      controlled by the client setting the value.  See Section 9 for
      additional considerations regarding privacy.  The attribute has

      "caseExact" as "true" and has a mutability of "readWrite".  The
      attribute is OPTIONAL.

   meta
      A complex attribute containing resource metadata.  All meta sub-
      attributes are asserted by the service provider and SHALL be
      ignored when provided by clients:

      resourceType  The name of the resource type of the resource.  This
         attribute has mutability of "readOnly" and has "caseExact" as
         "true".  The attribute is REQUIRED when provided by the service
         provider.

      created  The DateTime the resource was added to the service
         provider.  The attribute MUST be a DateTime.  This attribute
         has mutability of "readOnly".

      lastModified  The most recent DateTime the details of this
         resource were updated at the service provider.  If this
         resource has never been modified since its initial creation,
         the value MUST be the same as the value of created.  The
         attribute MUST be a DateTime and has mutability of "readOnly".
         The attribute is REQUIRED when provided by the service
         provider.

      location  The URI of the resource being returned.  This value MUST
         be the same as the "Content-Location" HTTP response header (see
         Section 3.1.4.2 [RFC7231]).  The attribute has mutability of
         "readOnly".  The attribute is REQUIRED when provided by the
         service provider.

      version  The version of the resource being returned.  This value
         must be the same as the ETag HTTP response header (See Sections
         2.1 and 2.3 of [RFC7232]).  The attribute has mutability of
         "readOnly" and has "caseExact" as "true".  The attribute is
         OPTIONAL subject to the service provider's support for
         versioning (see "Versioning Resources", Section 3.14
         [I-D.ietf-scim-api]).  If a service provider provides "version"
         (entity-tag) for a representation and the generation of that
         entity-tag does not satisfy all of the characteristics of a
         strong validator (see Section 2.1, [RFC7232]), then the origin
         server MUST mark the "version" (entity-tag) as weak by
         prefixing its opaque value with "W/" (case-sensitive).

3.2.  Defining New Resource Types

   SCIM may be extended to define new classes of resources by defining a
   resource type.  Each resource type defines the name, endpoint, base
   schema (the attributes), and any schema extensions registered for use
   with the resource type.  In order to offer new types of resources, a
   service provider defines the new resource type as specified in
   Section 6 and defines a schema representation (see Section 8.7).

3.3.  Attribute Extensions to Resources

   SCIM allows resource types to have extensions in addition to their
   core schema.  This is similar to how "ObjectClasses" are used in LDAP
   [RFC4512].  However, unlike LDAP there is no inheritance model; all
   extensions are additive (similar to LDAP Auxiliary Object Class).
   Each value in the "schemas" attribute indicates additive schema that
   MAY exist in a SCIM resource representation.  The "schemas" attribute
   MUST contain at least one value which SHALL be the base schema for
   the resource.  The "schemas" attribute MAY contain additional values
   indicating extended schemas that are in use.  Schema extensions
   SHOULD avoid redefining any attributes defined in this specification
   and SHOULD follow conventions defined in this specification.  Except
   for the base object schema, the schema extension URI SHALL be used as
   a JSON container to distinguish attributes belonging to the extension
   namespace from base schema attributes.  See Figure 5 for an example
   of the JSON representation of an extended User.

   In order to determine which URI value in the "schemas" attribute is
   the base schema and which is extended schema for any given resource,
   the resource's "resourceType" attribute value MAY be used to retrieve
   the resource's "ResourceType" schema ( Section 6 ).  See example
   "ResourceType" representation in Figure 8.

4.  SCIM Core Resources and Extensions

   This section defines the default resources schemas present in a SCIM
   server.  SCIM is not exclusive to these resources, and may be
   extended to support other resource types (see Section 3.2).

4.1.  User Resource Schema

   SCIM provides a resource type for "User" resources.  The core schema
   for "User" is identified using the URI:
   "urn:ietf:params:scim:schemas:core:2.0:User".  The following
   attributes are defined in addition to the core schema attributes:

4.1.1.  Singular Attributes

   userName
      A service provider unique identifier for the user, typically used
      by the user to directly authenticate to the service provider.
      Often displayed to the user as their unique identifier within the
      system (as opposed to "id" or "externalId", which are generally
      opaque and not user-friendly identifiers).  Each User MUST include
      a non-empty userName value.  This identifier MUST be unique across
      the service provider's entire set of Users.  The attribute is
      REQUIRED and is case-insensitive.

   name
      The components of the user's real name.  Service providers MAY
      return just the full name as a single string in the formatted sub-
      attribute, or they MAY return just the individual component
      attributes using the other sub-attributes, or they MAY return
      both.  If both variants are returned, they SHOULD be describing
      the same name, with the formatted name indicating how the
      component attributes should be combined.

      formatted  The full name, including all middle names, titles, and
         suffixes as appropriate, formatted for display (e.g., "Ms.
         Barbara Jane Jensen, III." ).

      familyName  The family name of the User, or last name in most
         Western languages (e.g., "Jensen" given the full name "Ms.
         Barbara Jane Jensen, III." ).

      givenName  The given name of the User, or first name in most
         Western languages (e.g., "Barbara" given the full name "Ms.
         Barbara Jane Jensen, III." ).

      middleName  The middle name(s) of the User (e.g., "Jane" given the
         full name "Ms.  Barbara Jane Jensen, III." ).

      honorificPrefix  The honorific prefix(es) of the User, or title in
         most Western languages (e.g., "Ms." given the full name "Ms.
         Barbara Jane Jensen, III." ).

      honorificSuffix  The honorific suffix(es) of the User, or suffix
         in most Western languages (e.g., "III." given the full name
         "Ms.  Barbara Jane Jensen, III." ).

   displayName
      The name of the user, suitable for display to end-users.  Each
      user returned MAY include a non-empty displayName value.  The name
      SHOULD be the full name of the User being described if known

      (e.g., "Babs Jensen" or "Ms.  Barbara J Jensen, III" ), but MAY be
      a username or handle, if that is all that is available (e.g.,
      "bjensen" ).  The value provided SHOULD be the primary textual
      label by which this User is normally displayed by the service
      provider when presenting it to end-users.

   nickName
      The casual way to address the user in real life, e.g., "Bob" or
      "Bobby" instead of "Robert".  This attribute SHOULD NOT be used to
      represent a User's username (e.g., bjensen or mpepperidge).

   profileUrl
      A URI that is a uniform resource locator (as defined in
      Section 1.1.3 [RFC3986]), that points to a location representing
      the user's online profile (e.g. a web page).  URIs are
      canonicalized per Section 6.2 of [RFC3986].

   title
      The user's title, such as "Vice President".

   userType
      Used to identify the organization to user relationship.  Typical
      values used might be "Contractor", "Employee", "Intern", "Temp",
      "External", and "Unknown" but any value may be used.

   preferredLanguage
      Indicates the user's preferred written or spoken languages and is
      generally used for selecting a localized User interface.  The
      value indicates the set of natural languages that are preferred.
      The format of the value is same as the Accept-Language header
      field (not including "Accept-Language:") of HTTP and is specified
      in Section 5.3.5 of [RFC7231].  The intent of this value is to
      enable cloud applications to perform matching of language tags
      [RFC4647] to the user's language preferences regardless of what
      may be indicated by a user agent (which might be shared), or in a
      non-user present interaction (such as in a delegated OAuth2
      [RFC6749] style interaction) where normal HTTP Accept-Language
      header negotiation cannot take place.

   locale
      Used to indicate the User's default location for purposes of
      localizing items such as currency, date time format, numerical
      representations, etc.  A valid value is a language tag as defined
      in [RFC5646].  Computer languages are explicitly excluded.

      A language tag is a sequence of one or more case-insensitive sub-
      tags, each separated by a hyphen character ("-", %x2D).  For
      backwards compatibility reasons, servers MAY accept tags separated

      by an underscore character ("_", %5F).  In most cases, a language
      tag consists of a primary language sub-tag that identifies a broad
      family of related languages (e.g., "en" = English) which is
      optionally followed by a series of sub-tags that refine or narrow
      that language's range (e.g., "en-CA" = the variety of English as
      communicated in Canada).  Whitespace is not allowed within a
      language tag.  Example tags include:

           fr, en-US, es-419, az-Arab, x-pig-latin, man-Nkoo-GN

      See [RFC5646] for further information.

   timezone
      The User's time zone in IANA Time Zone database format [RFC6557],
      also known as "Olson" timezone database format [Olson-TZ] ; For
      example: "America/Los_Angeles".

   active
      A Boolean value indicating the user's administrative status.  The
      definitive meaning of this attribute is determined by the service
      provider.  As a typical example, a value of true infers the user
      is able to login while a value of false implies the user's account
      has been suspended.

   password
      This attribute is intended to be used as a means to set, replace,
      or compare (i.e., filter for equality) a password.  The clear-text
      value or the hashed value of a password SHALL NOT be returnable by
      a service provider.  If a service provider holds the value
      locally, the value SHOULD be hashed.  When a password is set or
      changed, the clear text password SHOULD be:

      *  Prepared for international language comparison.  See
         Section 7.7 of [I-D.ietf-scim-api].

      *  Validated against server password policy.  Note: the definition
         and enforcment of password policy is beyond the scope of this
         document.

      *  And, is hashed or encrypted.  See Section 9.2 for acceptable
         hasing and encryption handling when storing or persisting for
         provisioning workflow reasons.

      A service provider that immediately passes the value on to another
      system or programming interface, MAY pass the value directly over
      a secured connection (e.g., TLS).  If the value needs to be
      temporarily persisted for a period of time (e.g., because of a

      workflow) before provisioning, then the value MUST be protected by
      some method such as encryption.

      Testing for an equality match MAY be supported if there is an
      existing stored hashed value.  When testing for equality, the
      service provider:

      *  Prepares the filter value for international language
         comparison.  See Section 7.7 of [I-D.ietf-scim-api].

      *  The service provider generates the salted hash of the filter
         value and test for a match with the locally held value.

      The mutability of the password attribute is "writeOnly" indicating
      the value MUST NOT be returned by a service provider in any form
      (the attribute characteristic "returned" is "never").

4.1.2.  Multi-valued Attributes

   The following multi-valued attributes are defined.

   emails
      E-mail addresses for the User.  The value SHOULD be specified
      according to [RFC5321].  Service providers SHOULD canonicalize the
      value according to [RFC5321], e.g., "bjensen@example.com" instead
      of "bjensen@EXAMPLE.COM".  The "display" sub-attribute MAY be used
      to return the canonicalized representation of the e-mail value.
      The "type" sub-attribute is used to provide a classification
      meaningful to the (human) user.  The user interface should
      encourage the use of basic values of "work", "home", and "other",
      and MAY allow additional type values to be used at the descretion
      of SCIM clients.

   phoneNumbers
      Phone numbers for the user.  The value SHOULD be specified
      according to the format in [RFC3966] e.g., 'tel:+1-201-555-0123'.
      Service providers SHOULD canonicalize the value according to
      [RFC3966] format, when appropriate.  The "display" sub-attribute
      MAY be used to return the canonicalized representation of the
      phone number value.  The sub-attribute "type" often has typical
      values of "work", "home", "mobile", "fax", "pager", and "other",
      and MAY allow more types to be defined by the SCIM clients.

   ims
      Instant messaging address for the user.  No official
      canonicalization rules exist for all instant messaging addresses,
      but service providers SHOULD, when appropriate, remove all
      whitespace and convert the address to lowercase.  The "type" sub-

Internet-Draft           draft-scim-core-schema                 May 2015


      attribute SHOULD take one of the following values: "aim", "gtalk",
      "icq", "xmpp", "msn", "skype", "qq", "yahoo", and "other",
      representing currently popular IM services at the time of writing.
      Service providers MAY add further values if new IM services are
      introduced and MAY specify more detailed canonicalization rules
      for each possible value.

   photos
      A URI that is a uniform resource locator (as defined in
      Section 1.1.3 [RFC3986]) that points to a resource location
      representing the user's image.  The resource MUST be a file (e.g.,
      a GIF, JPEG, or PNG image file) rather than a web page containing
      an image.  Service providers MAY return the same image at
      different sizes, though it is recognized that no standard for
      describing images of various sizes currently exists.  Note that
      this attribute SHOULD NOT be used to send down arbitrary photos
      taken by this user, but specifically profile photos of the user
      suitable for display when describing the user.  Instead of the
      standard canonical values for type, this attribute defines the
      following canonical values to represent popular photo sizes:
      "photo", "thumbnail".

   addresses
      A physical mailing address for this user.  Canonical type values
      of "work", "home", and "other".  The value attribute is a complex
      type with the following sub-attributes.  All sub-attributes are
      OPTIONAL.

      formatted  The full mailing address, formatted for display or use
         with a mailing label.  This attribute MAY contain newlines.

      streetAddress  The full street address component, which may
         include house number, street name, P.O.  box, and multi-line
         extended street address information.  This attribute MAY
         contain newlines.

      locality  The city or locality component.

      region  The state or region component.

      postalCode  The zipcode or postal code component.

      country  The country name component.  When specified the value
         MUST be in ISO 3166-1 alpha 2 "short" code format [ISO3166] ;
         e.g., the United States and Sweden are "US" and "SE",
         respectively.

   groups

Internet-Draft           draft-scim-core-schema                 May 2015


      A list of groups that the user belongs to, either thorough direct
      membership, nested groups, or dynamically calculated.  The values
      are meant to enable expression of common group or role based
      access control models, although no explicit authorization model is
      defined.  It is intended that the semantics of group membership
      and any behavior or authorization granted as a result of
      membership are defined by the service provider.  The canonical
      types "direct" and "indirect" are defined to describe how the
      group membership was derived.  Direct group membership indicates
      the user is directly associated with the group and SHOULD indicate
      that clients may modify membership through the "Group" resource.
      Indirect membership indicates user membership is transitive or
      dynamic and implies that clients cannot modify indirect group
      membership through the "Group" resource but MAY modify direct
      group membership through the "Group" resource which MAY influence
      indirect memberships.  If the SCIM service provider exposes a
      Group resource, the "value" sub-attribute MUST be the "id" and the
      "$ref" sub-attribute must be the URI of the corresponding "Group"
      resources to which the user belongs.  Since this attribute has a
      mutability of "readOnly", group membership changes MUST be applied
      via the Group Resource (Section 4.2).  The attribute has a
      mutability of "readOnly".

   entitlements
      A list of entitlements for the user that represent a thing the
      user has.  An entitlement MAY be an additional right to a thing,
      object, or service.  No vocabulary or syntax is specified and
      service providers and clients are expected to encode sufficient
      information in the value so as to accurately and without ambiguity
      determine what the user has access to.  This value has no
      canonical types though type may be useful as a means to scope
      entitlements.

   roles
      A list of roles for the user that collectively represent who the
      user is; e.g., "Student, Faculty".  No vocabulary or syntax is
      specified though it is expected that a role value is a String or
      label representing a collection of entitlements.  This value has
      no canonical types.

   x509Certificates
      A list of certificates associated with the resource (e.g., a
      User).  Each certificate is a DER encoded X.509 (see Section 4
      [RFC5280]), which MUST be base 64 encoded per Section 4 [RFC4648].

4.2.  Group Resource Schema

   SCIM provides a schema for representing groups, identified using the
   following schema URI: "urn:ietf:params:scim:schemas:core:2.0:Group".

   Group resources are meant to enable expression of common group or
   role based access control models, although no explicit authorization
   model is defined.  It is intended that the semantics of group
   membership and any behavior or authorization granted as a result of
   membership are defined by the service provider, and are considered
   out of scope for this specification.

   The following singular attribute is defined in addition to the common
   attributes defined in SCIM core schema:

   displayName
      A human readable name for the Group.  REQUIRED.

   The following multi-valued attribute is defined in addition to the
   common attributes defined in SCIM Core Schema:

   members
      A list of members of the Group.  While values MAY be added or
      removed, sub-attributes of members are "immutable".  The "value"
      sub-attribute must be the "id" and the "$ref" sub-attribute must
      be the URI of a SCIM resource, either a "User", or a "Group".  The
      intention of the "Group" type is to allow the service provider to
      support nested groups.  Service providers MAY require clients to
      provide a non-empty members value based on the "required" sub
      attribute of the "members" attribute in the "Group" resource
      schema.

4.3.  Enterprise User Schema Extension

   The following SCIM extension defines attributes commonly used in
   representing users that belong to, or act on behalf of a business or
   enterprise.  The enterprise user extension is identified using the
   following schema URI:
   "urn:ietf:params:scim:schemas:extension:enterprise:2.0:User".

   The following Singular Attributes are defined:

   employeeNumber
      A string identifier, typically numeric or alpha-numeric, assigned
      to a person, typically based on order of hire or association with
      an organization.

   costCenter

      Identifies the name of a cost center.

   organization
      Identifies the name of an organization.

   division
      Identifies the name of a division.

   department
      Identifies the name of a department.

   manager
      The user's manager.  A complex type that optionally allows service
      providers to represent organizational hierarchy by referencing the
      "id" attribute of another User.

      value  The "id" of the SCIM resource representing the user's
         manager.  RECOMMENDED.

      $ref  The URI of the SCIM resource representing the User's
         manager.  RECOMMENDED.

      displayName  The displayName of the user's manager.  This
         attribute is OPTIONAL and mutability is "readOnly".

5.  Service Provider Configuration Schema

   SCIM provides a schema for representing the service provider's
   configuration identified using the following schema URI:
   "urn:ietf:params:scim:schemas:core:2.0:ServiceProviderConfig"

   The service provider configuration resource enables a service
   provider to discover SCIM specification features in a standardized
   form as well as provide additional implementation details to clients.
   All attributes have a mutability of "readOnly".  Unlike other core
   resources, the "id" attribute is not required for the service
   provider configuration resource.

   The following Singular Attributes are defined in addition to the
   common attributes defined in Core Schema:

   documentationUrl
      An HTTP addressable URL pointing to the service provider's human
      consumable help documentation.

   patch

   The following multi-valued attribute is defined in addition to the
   common attributes defined in core schema:

   authenticationSchemes
      A complex type that specifies supported Authentication Scheme
      properties.  This attribute defines the following canonical values
      to represent common schemes: "oauth", "oauth2",
      "oauthbearertoken", "httpbasic", and "httpdigest".  To enable
      seamless discovery of configuration, the service provider SHOULD,
      with the appropriate security considerations, make the
      authenticationSchemes attribute publicly accessible without prior
      authentication.  REQUIRED.

      name  The common authentication scheme name; e.g., HTTP Basic.
         REQUIRED.

      description  A description of the Authentication Scheme.
         REQUIRED.

      specUrl  An HTTP addressable URL pointing to the Authentication
         Scheme's specification.  OPTIONAL.

      documentationUrl  An HTTP addressable URL pointing to the
         Authentication Scheme's usage documentation.  OPTIONAL.

6.  ResourceType Schema

   The "ResourceType" schema specifies the meta-data about a resource
   type.  Resource type resources are READ-ONLY and identified using the
   following schema URI:
   "urn:ietf:params:scim:schemas:core:2.0:ResourceType".  Unlike other
   core resources, all attributes are REQUIRED unless otherwise
   specified.  The "id" attribute is not required for the resource type
   resource.

   The following Singular Attributes are defined:

   id
      The resource type's server unique id.  Often this is the same
      value as the "name" attribute.  OPTIONAL

   name
      The resource type name.  When applicable service providers MUST
      specify the name specified in the core schema specification; e.g.,
      "User" or "Group".  This name is referenced by the
      "meta.resourceType" attribute in all resources.

      The resource type's human readable description.  When applicable
      service providers MUST specify the description specified in the
      core schema specification.

   endpoint
      The resource type's HTTP addressable endpoint relative to the Base
      URL of the service provider; e.g., "Users".

   schema
      The resource type's primary/base schema URI; e.g.,
      "urn:ietf:params:scim:schemas:core:2.0:User".  This MUST be equal
      to the "id" attribute of the associated "Schema" resource.

   schemaExtensions
      A list of URIs of the resource type's schema extensions.
      OPTIONAL.

      schema  The URI of an extended schema; e.g., "urn:edu:2.0:Staff".
         This MUST be equal to the "id" attribute of a "Schema"
         resource.  REQUIRED.

      required  A Boolean value that specifies whether the schema
         extension is required for the resource type.  If true, a
         resource of this type MUST include this schema extension and
         include any attributes declared as required in this schema
         extension.  If false, a resource of this type MAY omit this
         schema extension.  REQUIRED.

7.  Schema Definition

   This section defines a way to specify the schema in use by resources
   available and accepted by a SCIM service provider.  For each
   "schemas" URI value, this schema specifies the defined attribute(s)
   and their characteristics (mutability, returnability, etc).  For
   every schema URI used in a resource object, there is a corresponding
   "Schema" resource.  "Schema" resources have mutability of "readOnly"
   and are identified using the following schema URI:

   urn:ietf:params:scim:schemas:core:2.0:Schema

   Unlike other core resources the "Schema" resource MAY contain a
   complex object within a sub-attribute and all attributes are REQUIRED
   unless otherwise specified.

   The following Singular Attributes are defined:

   id

Internet-Draft           draft-scim-core-schema                 May 2015


      The unique URI of the schema.  When applicable service providers
      MUST specify the URI specified in the core schema specification;
      e.g., "urn:ietf:params:scim:schemas:core:2.0:User".  Unlike most
      other schemas, which use some sort of a GUID for the "id", the
      schema "id" is a URI so that it can be registered and is portable
      between different service providers and clients.

   name
      The schema's human readable name.  When applicable service
      providers MUST specify the name specified in the core schema
      specification; e.g., "User" or "Group".  OPTIONAL.

   description
      The schema's human readable description.  When applicable service
      providers MUST specify the description specified in the core
      schema specification.  OPTIONAL.

   The following multi-valued attribute is defined:

   attributes
      A complex type with the following set of sub-attributes that
      defines service provider attributes and their qualities:

      name  The attribute's name.

      type  The attribute's data type.  Valid values are: "string",
         "boolean", "decimal", "integer", "dateTime", "reference", and
         "complex".  When an attribute is of type "complex", there
         SHOULD be a corresponding schema attribute "subAttributes"
         defined listing the sub-attribtues of the attribute.

      subAttributes  When an attribute is of type "complex",
         "subAttributes" defines set of sub-attributes. "subAttributes"
         has the same schema sub-attributes as "attributes".

      multiValued  Boolean value indicating the attribute's plurality.

      description  The attribute's human readable description.  When
         applicable service providers MUST specify the description
         specified in the core schema specification.

      required  A Boolean value that specifies if the attribute is
         required.

      canonicalValues  A collection of suggested canonical values that
         MAY be used.  Example: "work" and"home".  In some cases service
         providers MAY choose to ignore unsupported values.  The use of
         canonicalValues is OPTIONAL.

      caseExact  A Boolean value that specifies if the String attribute
         is case sensitive.  The server SHALL use case sensitivity when
         evaluating filters.  For attributes that are case exact, the
         server SHALL preserve case for any value submitted.  If the
         attribute is case insensitive, the server MAY alter case for a
         submitted value.  Case sensitivity also impacts how attribute
         values MAY be compared against filter values (see section
         3.4.2.2 [I-D.ietf-scim-api]).

      mutability  A single keyword indicating the circumstances under
         which the value of the attribute can be (re)defined:

         readOnly  The attribute SHALL NOT be modified.

         readWrite  The attribute MAY be updated and read at any time.
            DEFAULT.

         immutable  The attribute MAY be defined at resource creation
            (e.g., POST) or at record replacement via request (e.g., a
            PUT).  The attribute SHALL NOT be updated.

         writeOnly  The attribute MAY be updated at any time.  Attribute
            values SHALL NOT be returned (e.g., because the value is a
            stored hash).  Note: an attribute with mutability of
            "writeOnly" usually also has a returned setting of "never".

      returned  A single keyword that indicates when an attribute and
         associated values are returned in response to a GET request or
         in response to a PUT, POST, or PATCH request.  Valid keywords
         are:

         always  The attribute is always returned regardless of the
            contents of the "attributes" parameter.  For example, "id"
            is always returned to identify a SCIM resource.

         never  The attribute is never returned.  This may occur because
            the original attribute value is not retained by the service
            provider (e.g., such as with a hashed value).  A service
            provider MAY allow attributes to be used in a search filter.

         default  The attribute is returned by default in all SCIM
            operation responses where attribute values are returned.  If
            the GET request "attributes" parameter is specified,
            attribute values are only returned if the attribute is named
            in the attributes parameter.  DEFAULT.

         request  The attribute is returned in response to any PUT,
            POST, or PATCH operations if the attribute was specified by

            the client (for example, the attribute was modified).  The
            attribute is returned in a SCIM query operation only if
            specified in the "attributes" parameter.

      uniqueness  A single keyword value that specifies how the service
         provider enforces uniqueness of attribute values.  A server MAY
         reject an invalid value based on uniqueness by returning HTTP
         Response code 400 (Bad Request).  A client MAY enforce
         uniqueness on the client-side to a greater degree than the
         service provider enforces.  For example, a client could make a
         value unique while the server has uniqueness of "none".  Valid
         keywords are:

         none  The values are not intended to be unique in any way.
            DEFAULT.

         server  The value SHOULD be unique within the context of the
            current SCIM endpoint (or tenancy) and MAY be globally
            unique (e.g., a "username", email address, or other server
            generated key or counter).  No two resources on the same
            server SHOULD possess the same value.

         global  The value SHOULD be globally unique (e.g., an email
            address, a GUID, or other value).  No two resources on any
            server SHOULD possess the same value.

      referenceTypes  A multi-valued array of JSON strings that indicate
         the SCIM resource types that may be referenced.  Valid values
         are:

         +  A SCIM resource type (e.g., "User" or "Group"),

         +  "external" - indicating the resource is an external resource
            (e.g., such as a photo), or

         +  "uri" - indicating that the reference is to a service
            endpoint or an identifier (e.g., such as a schema urn).

         This attribute is only applicable for attributes that are of
         type "reference" (Section 2.3.7).

9.  Security Considerations

9.1.  Protocol

   SCIM data is intended to be exchanged using SCIM Protocol.  It is
   important when handling data to implement the security considerations
   outlined in Section 7 of [I-D.ietf-scim-api].

9.2.  Password and Other Sensitive Security Data

   Passwords and other attributes related to security credentials are of
   extreme sensitive nature and require special handling when
   transmitted or stored.  While SCIM Protocol uses clear-text passwords
   for setting and equality testing purposes, password values MUST NOT
   be stored in clear-text form.

   Administrators should undertake industry best practices to protect
   the storage of credentials and in particular SHOULD follow
   recommendations outlines in Section 5.1.4.1 [RFC6819].  These
   requirements include but are not limited to:

   o  Provide injection attack counter measures (e.g., by validating all
      inputs and parameters),

   o  No cleartext storage of credentials,





Hunt, et al.            Expires November 12, 2015              [Page 79]


Internet-Draft           draft-scim-core-schema                 May 2015


   o  Store credentials using an encrypted protection mechanism (e.g.
      hashing), and

   o  Where possible, avoid passwords as the sole form of
      authentication, and consider use of asymmetric cryptography based
      credentials.

9.3.  Privacy

   The SCIM Core schema defines attributes that are sensitive and may be
   considered personally identifying information (PII).  These privacy
   considerations should be considered for extensions as well as the
   schema defined in this specification.

   For the purposes of this specification personally identifying
   information is defined as any attribute that MAY be used as a unique
   key to identify a person (e.g., User).  Since other information MAY
   be used in combination to identify an individual, all attributes in
   SCIM are considered "sensitive" personal information.  Consult
   regional jurisdictions to see if there are special considerations for
   the handling of personal and PII information.

   Information should be shared on an as-needed basis.  A SCIM client
   should limit information to what it believes a service provider
   requires, and a SCIM service provider, should only accept information
   it needs.  Clients and service providers should take into
   consideration that personal information is being conveyed across
   technical (e.g., protocol and applications), administrative (e.g.
   organizational, corporate), and jurisdictional boundaries.  In
   particular information security and privacy must be considered.

   Security service level agreements for the handling of these
   attributes are beyond the scope of this document, but are to be
   carefully considered by implementers and deploying organizations.

   Please see the Privacy Considerations section of [I-D.ietf-scim-api],
   for more protocol specific considerations for handling of SCIM
   information.

   SCIM defines attributes such as "id" and "externalId" and SCIM
   resource URIs which causes new PII information to be generated which
   is important to the way SCIM protocol identifies and locates
   resources.  Where possible, it is suggested that service providers
   take the following remediations:

   o  Where possible, assign and bind identifiers to specific tenants
      and/or clients.  When multiple tenants are able to reference the
      same resource, they should do so via separate identifiers (id or

      externalId).  This ensures that separate domains linked to the
      same information can not perform identifier correlation.

   o  In the case of "externalId", if multiple values are supported, use
      access control to restrict access to the client domain that
      assigned the "externalId" value.

   o  Ensure that access to data is appropriately restricted to
      authorized parties with a need-to-know.

   o  When persisted, the appropriate protection mechanisms are in place
      to restrict access by unauthorized parties including
      administrators or parties with access to backup data.

10.  IANA Considerations

10.1.  Registration of SCIM URN Sub-namespace & SCIM Registry

   IANA is requested to add an entry to the 'IETF URN Sub-namespace for
   Registered Protocol Parameter Identifiers' registry and create a sub-
   namespace for the Registered Parameter Identifier as per [RFC3553]:
   "urn:ietf:params:scim".

   To manage this sub-namespace, IANA is requested to create the "SCIM"
   Registry which shall be used to manage entries within the
   "urn:ietf:params:scim" namespace.  The registry description is as
   follows:

   o  Registry name: SCIM

   o  Specification: [this document]

   o  Repository: [see Section 10.2]

   o  Index value: values [see Section 10.2]

10.2.  URN Sub-Namespace for SCIM

   SCIM schemas and SCIM messages utilize URIs to identify the schema in
   use or other relevant context.  This section creates and registers an
   IETF URN Sub-namespace for use in the SCIM specifications and future
   extensions.

10.2.1.  Specification Template

   Namespace ID:

      The Namespace ID "scim" is requested.

      Date: [[insert final submission date]]

   Declared registrant of the namespace:

      Registering organization
         The Internet Engineering Task Force

      Designated contact
         A designated expert will monitor the SCIM public mailing list,
         "scim@ietf.org".

   Declaration of Syntactic Structure:

      The Namespace Specific String (NSS) of all URNs that use the
      "scim" NID shall have the following structure:

   urn:ietf:params:scim:{type}:{name}{:other}

      The keywords have the following meaning:

      type
         The entity type which is either "schemas" or "api".

      name
         A required US-ASCII string that conforms to the URN syntax
         requirements (see [RFC2141] ) and defines a major namespace of
         a schema used within SCIM (e.g., "core", which is reserved for
         SCIM specifications).  The value MAY also be an industry name
         or organization name.

      other
         Any US-ASCII string that conforms to the URN syntax
         requirements (see [RFC2141] ) and defines the sub-namespace
         (which MAY be further broken down in namespaces delimited by
         colons) as needed to uniquely identify a schema.

   Relevant Ancillary Documentation:

      None

   Identifier Uniqueness Considerations:

      The designated contact shall be responsible for reviewing and
      enforcing uniqueness.

Internet-Draft           draft-scim-core-schema                 May 2015


   Identifier Persistence Considerations:

      Once a name has been allocated it MUST NOT be re-allocated for a
      different purpose.  The rules provided for assignments of values
      within a sub-namespace MUST be constructed so that the meaning of
      values cannot change.  This registration mechanism is not
      appropriate for naming values whose meaning may change over time.

      As the SCIM specifications are updated and the SCIM protocol
      version is adjusted, a new registration will be made when
      significant changes are made.  Example,
      "urn:ietf:params:scim:schemas:core:1.0 (externally defined, not
      previously registered)" and
      "urn:ietf:params:scim:schemas:core:2.0".

   Process of Identifier Assignment:

      Identifiers with namespace type "schema" (e.g.,
      "urn:ietf:params:scim:schemas" ) are assigned after the review of
      the assigned contact via the SCIM public mailing list,
      "scim@ietf.org" as documented in Section 10.3.

      Namespaces with type "api" (e.g., "urn:ietf:params:scim:api") and
      "param" (e.g., "urn:ietf:params:scim:param" ) are reserved for
      IETF approved SCIM specifications.

   Process of Identifier Resolution:

      The namespace is not currently listed with a Resolution Discovery
      System (RDS), but nothing about the namespace prohibits the future
      definition of appropriate resolution methods or listing with an
      RDS.

   Rules for Lexical Equivalence:

      No special considerations; the rules for lexical equivalence
      specified in [RFC2141] apply.

   Conformance with URN Syntax:

      No special considerations.

   Validation Mechanism:

      None specified.

   Scope:

10.3.  Registering SCIM Schemas

   This section defines the process for registering new SCIM schemas
   with IANA in the "SCIM" registry (see Section 10.1).  A schema URI is
   used as a value in the schemas attribute (Section 3) for the purpose
   of distinguishing extensions used in a SCIM resource.

10.3.1.  Registration Procedure

   The IETF has created a mailing list, scim@ietf.org, which can be used
   for public discussion of SCIM schema proposals prior to registration.
   Use of the mailing list is strongly encouraged.  The IESG has
   appointed a designated expert who will monitor the scim@ietf.org
   mailing list and review registrations.

   Registration of new "core" (e.g. in the namespace
   "urn:ietf:params:scim:schemas:core") and "API" schemas (e.g., in the
   namespace "urn:ietf:params:scim:api") MUST be reviewed by the
   designated expert and published in an RFC.  An RFC is REQUIRED for
   the registration of new value data types that modify existing
   properties.  An RFC is also REQUIRED for registration of SCIM schema
   URIs that modify SCIM schema previously documented in a existing RFC.
   URN's within the "urn:ietf:params:scim", but outside the above
   namespaces MAY be registered with a simple review (e.g. check for
   SPAM) by the designated expert on a first-come-first-served basis.

   The registration procedure begins when a completed registration
   template, defined in the sections below, is sent to scim@ietf.org and
   iana@iana.org.  Within two weeks, the designated expert is expected
   to tell IANA and the submitter of the registration whether the
   registration is approved, approved with minor changes, or rejected
   with cause.  When a registration is rejected with cause, it can be
   re-submitted if the concerns listed in the cause are addressed.
   Decisions made by the designated expert can be appealed to the IESG
   Applications Area Director, then to the IESG.  They follow the normal
   appeals procedure for IESG decisions.

   Once the registration procedure concludes successfully, IANA creates
   or modifies the corresponding record in the SCIM schema registry.
   The completed registration template is discarded.

   An RFC specifying new schema URI MUST include the completed
   registration templates, which MAY be expanded with additional
   information.  These completed templates are intended to go in the
   body of the document, not in the IANA Considerations section.  The
   RFC SHOULD include any attributes defined.

10.3.2.  Schema Registration Template

   A SCIM schema URI is defined by completing the following template:

   Schema URI:  Schema URI: A unique URI for the SCIM schema extension.

   Schema Name:  A descriptive name of the schema extension (e.g.,
      Generic Device)

   Intended or Associated Resource Type:  A value defining the resource
      type (e.g., "Device").

   Purpose:  A description of the purpose of the extension and/or its
      intended use.

   Single-value Attributes:  A list and description of single-valued
      attributes defined including complex attributes.

   Multi-valued Attributes:  A list and description of multi-valued
      attributes defined including complex attributes.

10.4.  Initial SCIM Schema Registry

   The IANA is requested to populate the "SCIM" registry with the
   following registries for SCIM schema URIs with pointers to
   appropriate reference documents.  Note: the Schema URI broken into
   two lines for readability.
