Internet-Draft           Domain Name Data Escrow              March 2011


1.  Introduction

   Registration Data Escrow is the process by which an Internet
   Registration Organization (e.g., a registry, registrar, etc.)
   periodically submits data deposits to a third party called an Escrow
   Agent.  These deposits comprise the minimum data needed by a third
   party to resume operations if the registration organization could not
   function and was unable or unwilling to facilitate an orderly
   transfer of service.  For a domain name registry or registrar the
   data to be deposited includes all the objects related to registered
   domain names, e.g., contacts, name servers, etc.

   The goal of data escrow is higher resiliency of registration
   services, for the benefit of Internet users.  The beneficiaries of a
   registration organization are not just those registering information
   there, but all relying parties that need to identify the owners of
   objects.

   In the context of domain name registries, registration data escrow is
   a requirement for the current generic top-level domains and it is
   expected to be for new registries.  Some country code top-level
   domain managers are also currently escrowing data.  There is also a
   similar requirement for ICANN's generic top-level domain accredited
   registrars.

   This document specifies a format and contents of Data Escrow deposits
   for Domain Name Registration Organizations.


2.  Terminology

   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 BCP 14, RFC 2119
   [RFC2119].

   DEPOSIT.  Deposits can be of three kinds: Full, Differential or
   Incremental.  For all kinds of Deposits, the Universe of Registry
   objects to be considered for data escrow are those objects necessary
   in order to offer the Registry Services.

   DIFFERENTIAL DEPOSIT.  Contains data that reflects all transactions
   involving the database that were not reflected in the last previous
   Full, Incremental or Differential Deposit, as the case may be.
   Differential deposit files will contain information from all database
   objects that were added, modified or deleted since the previous
   Deposit was completed as of its defined Timeline Watermark.

Internet-Draft           Domain Name Data Escrow              March 2011


   ESCROW AGENT.  The organization designated by the Registry or the
   Third-Party Beneficiary to receive and guard Data Escrow Deposits
   from the Registry.

   FULL DEPOSIT.  Contains the Registry Data that reflects the current
   and complete Registry Database and will consist of data that reflects
   the state of the registry as of a defined Timeline Watermark for the
   deposit.

   INCREMENTAL DEPOSIT.  Contains data that reflects all transactions
   involving the database that were not reflected in the last previous
   Full Deposit.  Incremental Deposit files will contain information
   from all database objects that were added, modified or deleted since
   the previous Full Deposit was completed as of its defined Timeline
   Watermark.  If the Timeline Watermark of an Incremental Deposit were
   to cover the Watermark of another (Incremental or Differential)
   Deposit since the last Full Deposit, the former Deposit MUST contain
   the transactions of the later Deposit.

   REGISTRY.  The organization providing Registry Services for a RCDN.

   REGISTRY-CLASS DOMAIN NAME (RCDN): Refers to a top-level domain (TLD)
   or any other domain name at any level in the DNS tree for which a
   Registry (either directly or through and affiliate company) provides
   Registry Services for other organizations or individuals.  For
   example: .COM, .ORG, .BIZ, .CO.JP, .ORG.MX.

   REGISTRY SERVICES.  Services offered by the Registry critical to the
   following tasks: the provisioning of domain names on receipt of
   requests and data from registrars; responding to registrar queries
   for status information relating to the DNS servers for the RCDN;
   dissemination of RCDN zone files; operation of the Registry DNS
   servers; and responding to queries for contact and other information
   concerning DNS registrations in the RCDN.  Any other products or
   services that only a Registry is capable of providing, by reason of
   its designation as the Registry.  Typical examples of Registry
   Services are: DNS resolution for the RCDN, WHOIS and EPP.

   THIRD-PARTY BENEFICIARY.  Is the organization that, under
   extraordinary circumstances, would receive the escrow Deposits the
   Registry transferred to the Escrow Agent.  This organization could be
   a backup Registry, Registry regulator, contracting party of the
   Registry, etc.

   TIMELINE WATERMARK.  Point in time on which to base the collecting of
   database objects for a Deposit.  Deposits are expected to be
   consistent to that point in time.

Internet-Draft           Domain Name Data Escrow              March 2011


3.  Problem Scope

   Starting a few years ago, the issue of Registry continuity has been
   carefully considered in the gTLD and ccTLD space.  Various
   organizations have carried out a risk analysis and developed Business
   Continuity Plans to deal with those risks, should they materialize.

   One of the solutions considered and used, especially in the gTLD
   space, is Registry Data Escrow as a way to ensure the Continuity of
   Registry Services in the extreme case of Registry failure.

   So far, almost every Registry that uses Registry Data Escrow has its
   own specification.  It is anticipated that more Registries will be
   implementing Escrow especially with the advent of the new gTLD
   program, compounding this issue.

   Therefore, it would seem beneficial to have a standardized
   specification for Registry Data Escrow that can be used by any
   Registry to submit its Deposits.

   A solution to the problem at hand SHALL clearly identify the format
   and contents of the Deposits a Registry has to make, such that a
   different Registry would be able to rebuild the Registry Services of
   the former, without its help, in a timely manner, with minimum
   disruption to Registrants, Registrars and Internet users.

   Since the list and details of Registry Services vary from Registry to
   Registry, the solution SHALL provide mechanisms that allow its
   extensibility to accommodate variations and extensions of the
   Registry Services.

   Given the confidentiality and importance of some of the information
   that is handled in order to offer the Registry Services, the solution
   SHALL define confidentiality and integrity mechanisms when handling
   the Registry data.

   The solution SHALL NOT include in the specification transient objects
   that can be recreated by the new Registry, particularly those of
   delicate confidentiality, e.g., DNSSEC KSK/ZSK private keys.

   Details that are a matter of policy SHOULD be identified as such for
   the benefit of the implementers.

   Legal issues around Data Escrow and the overall question of the use
   of Registry Data Escrow are outside of scope of this document.

Internet-Draft           Domain Name Data Escrow              March 2011


4.  General Conventions

4.1.  Date and Time

   Numerous fields indicate "dates", such as the creation and expiry
   dates for domains.  These fields SHALL contain timestamps indicating
   the date and time in UTC as specified in [RFC3339], with no offset
   from the zero meridian.

4.2.  Country names

   Country identifiers SHALL be represented using two character
   identifiers as specified in [ISO-3166-1].

4.3.  Telephone numbers

   Telephone numbers (both voice and fax) SHALL be formatted based on
   structures defined in [ITU-E164].  Telephone numbers described in
   this specification are character strings that MUST begin with a plus
   sign ("+", ASCII value 0x002B), followed by a country code defined in
   [ITU-E164], followed by a dot (".", ASCII value 0x002E), followed by
   a sequence of digits representing the telephone number.

4.4.  IP addresses

   IP addresses syntax MUST conform either to, Internet Protocol
   [RFC0791], for IPv4 addresses, or IP Version 6 Addressing
   Architecture [RFC4291], for IPv6 addresses.


5.  Protocol Description

   The following is a format for Data Escrow deposits as produced by an
   Internet Registry.  Only the format of the objects deposited is
   defined, nothing is prescribed about the way to transfer such
   deposits between the Registry and the Escrow Agent or vice versa.
   The format is based on EPP [RFC5730] and related RFCs by Scott
   Hollenbeck.

   The protocol intends to be object agnostic allowing the "overload" of
   abstract elements using the "substitutionGroup" attribute to define
   the actual elements of an object to be escrowed.

5.1.  Root element <deposit>

   The container or root element for a Registry Data Escrow deposits is
   <deposit>.  This element contains the following child elements:
   watermark, deletes, contents, and extension.  The latter is explained



Arias & Noguchi        Expires September 15, 2011               [Page 6]


Internet-Draft           Domain Name Data Escrow              March 2011


   in Section 8.  This element also contains the following attributes:

   o  A "type" attribute that MUST be used to identify the kind of
      deposit: FULL, INCR (Incremental) or DIFF (Differential).

   o  An "id" attribute that MUST be used to uniquely identify the
      escrow deposit.  Each registry is responsible for maintaining its
      own escrow deposits identifier space to ensure uniqueness.

   o  An OPTIONAL "prevId" attribute that can be used to identify the
      previous incremental, differential or full escrow deposit.  This
      attribute MUST be used in Differential Deposits ("DIFF" type).

   o  An OPTIONAL "resend" attribute that is used to identify resend
      attempts in case of previous failure.  The first time a deposit is
      attempted to be sent, the attribute MUST be zero; The second
      attempt to send (first resend attempt) the attribute MUST be set
      to one; and so on.  This would be used when for example, the
      previous deposit was not received complete, it failed verification
      at the receiving party, etc.

   Example of root element object:


   <?xml version="1.0" encoding="UTF-8"?>
   <rde:deposit
       xmlns:rde="urn:ietf:params:xml:ns:rde-1.0"
       ...
       type="FULL"
       id="FULL-20101017001" prevId="FULL-20101010001">
       <rde:watermark>2010-10-18T00:00:00Z</rde:watermark>
       <rde:deletes>
          ...
       </rde:deletes>
       <rde:contents>
          ...
       </rde:contents>
   </rde:deposit>

5.2.  Child <watermark> element

   A <watermark> element contains the data-time correspondent to the
   Timeline Watermark of the deposit.

   Example of <watermark> element object:

Internet-Draft           Domain Name Data Escrow              March 2011


   <?xml version="1.0" encoding="UTF-8"?>
   <rde:deposit
       xmlns:rde="urn:ietf:params:xml:ns:rde-1.0"
       ...
       type="FULL"
       id="FULL-20101017001" prevId="FULL-20101010001">
       <rde:watermark>2010-10-18T00:00:00Z</rde:watermark>
       ...
   </rde:deposit>

5.3.  Child <deletes> element

   This element SHOULD only be present in deposits of type Incremental
   or Differential.  It contains the list of objects that were deleted
   since the base previous deposit.  Each object in this section SHALL
   contain an ID for the object deleted.

   This section of the deposit SHOULD NOT be present in Full deposits.
   When rebuilding a registry it SHOULD be ignored if present in a Full
   deposit.

   The specification for each object to be escrow SHALL identify the
   identificator to be used to reference the object to be deleted.

   Example of <deletes> element object:


   <?xml version="1.0" encoding="UTF-8"?>
   <rde:deposit
       xmlns:rde="urn:ietf:params:xml:ns:rde-1.0"
       ...
       <rde:deletes>
           <rdeObj1:delete>
               <rdeObj1:name>foo.test</rdeObj1:name>
               <rdeObj1:name>bar.test</rdeObj1:name>
           </rdeObj1:delete>
           <rdeObj2:delete>
               <rdeObj2:id>sh8013-TEST</rdeObj2:id>
               <rdeObj2:id>co8013-TEST</rdeObj2:id>
           </rdeObj2:delete>
       </rde:deletes>
       ...
   </rde:deposit>

5.4.  Child <contents> element

   This element of the deposit contains the actual objects in the
   deposit.  It SHALL be present in all type of deposits.  It contains
   the data for the objects to be escrowed.  The actual objects have to
   be specified individually.  This element MAY also contain an
   extension element allowing extending the format.

   In the case of Incremental or Differential deposits, the objects
   indicate whether the object was added or modified after the base
   previous deposit.  In order to distinguish between one and the other,
   it will be sufficient to check existence of the referenced object in
   the base previous deposit.

   When applying Incremental or Differential deposits, i.e., when
   rebuilding the registry from data escrow deposits, the order of the
   <deletes> and <contents> elements is important.  First, all the
   deletes MUST be applied and then the adds and updates, i.e., first
   apply what is in <deletes> and later what is in <contents>.

   Example of <contents> element object:


   <?xml version="1.0" encoding="UTF-8"?>
   <rde:deposit
       xmlns:rde="urn:ietf:params:xml:ns:rde-1.0"
       ...
       <rde:contents>
           ...
           <rdeObj1:contents>
               <rdeObj1:element1>
                   <rdeObj1:child1>Object1 specific.</rdeObj1:child1>
                   ...
               </rdeObj1:element1>
               <rdeObj2:element2 id="id12345">
                   <rdeObj2:field1>Object2 specific.</rdeObj2:field1>

6.  Object Description

   This section describes the base objects defined in EPP: domains,
   hosts and contacts with the addition of registrars, IDN Table
   References, IDNs and EPP parameters.

6.1.  RDE Domain Object

   The RDE domain object is based on the EPP domain name mapping in
   [RFC5731].  There are two elements used in this format related to
   domains: the domain object per se, used inside the <contents> element
   and the <rdeDomain:delete> object used inside the <deletes> element.

6.1.1.  <domain> object

   The domain element is based on the EPP domain <info> response for an
   authorized client (see Section 3.1.2. of [RFC5731]) with some
   additions, including the data from an EPP <transfer> Query Response,
   see Section 3.1.3. of [RFC5731], and data from the EPP <secDns:
   create> command, see Section 5.2.1. of [RFC5910].

   Example of a domain object:

6.4.  RDE Registrar Object

   The RDE registrar object is based on the EPP contact name mapping
   previously described.  There are two elements used in this format
   related to registrars: the registrar object per se, used inside the
   <contents> element and the <rdeRegistrar:delete> object used inside
   the <deletes> element.

6.4.1.  <registrar> object

   The <registrar> element contains the following child elements:

   o  An <id> element that contains the Registry-unique identifier of
      the registrar object.  This <id> has a superordinate relationship
      to a subordinate <clID>, <crID> or <upID> of domain, contact and
      host objects.

   o  An OPTIONAL <icannId> element that contains the ID assigned by
      ICANN.

   o  One or two <postalInfo> elements that contain postal- address
      information.  Two elements are provided so that address
      information can be provided in both internationalized and
      localized forms; a "type" attribute is used to identify the two
      forms.  If an internationalized form (type="int") is provided,
      element content MUST be represented in a subset of UTF-8 that can
      be represented in the 7-bit US-ASCII character set.  If a
      localized form (type="loc") is provided, element content MAY be
      represented in unrestricted UTF-8.  The <postalInfo> element

         child elements:

         +  One, two, or three OPTIONAL <street> elements that contain
            the registrar's street address.

         +  A <city> element that contains the registrar's city.

         +  An OPTIONAL <sp> element that contains the registrar's state
            or province.

      for the human or organizational social information objects
      associated with the registrar object.

   o  A <crDate> element that contains the date and time of registrar-
      object creation.

   o  A <upDate> element that contains the date and time of the most
      recent RDE registrar-object modification.  This element MUST NOT
      be present if the rdeRegistrar object has never been modified.

   o  An OPTIONAL <authInfo> element that contains authorization
      information associated with the registar object to allow access to
      registry systems.  This specification describes password-based
      authorization information, though other mechanisms are possible.

6.5.  RDE IDN Table Reference

   The RDE Internationalized Domain Names (IDN) Table reference is a
   pseudobject that is used to provide a short reference to the IDN
   Table used in IDN registrations.  The <idnTableRef> element has an
   "id" attribute that is used to uniquely identify an IDN Table stored
   externally.

   The <idnTableRef> has only one child element, <url> that contains the
   URL of the IDN table that is being referenced.

   Example of <idnTableRef> object:


  ...
  <rdeIDN:idnTableRef id="cl-es">
      <rdeIDN:url>

6.6.  RDE IDN object

6.6.1.  IDN variants Handling

   Depending on the Registration Policy in place in the Registry; for a
   particular IDN, there may be multiple variant domains either
   registered, reserved or blocked:

   1.  If the IDN is considered to be the preferred variant, base or
       primary IDN upon which the IDN variants are formed, the IDN SHALL
       be tagged as "canonical".

   2.  If the IDN variant is actually registered, bundled with its
       canonical domain name in the Registry system, the variant SHALL
       be tagged as "registered".

   3.  If only the holder of the canonical domain name is allowed to
       register the IDN variant but it is not actually registered, the
       variant SHALL be tagged as "reserved".

   4.  If the IDN variant is considered undesirable for registration,
       the variant SHALL be tagged as "blocked".

   IDN variants tagged as "reserved" or "blocked" SHOULD be escrowed if

   explicitly declared and known.

6.6.2.  <idn> object

   The <idn> element contains the following child elements:

   o  An <aName> element that contains the ASCII Compatible Encoding
      (ACE) of an IDN.

   o  An OPTIONAL <uName> element that contains the name of the IDN in
      Unicode character set.  It SHOULD be provided if available.

   o  A <type> element that indicates the type of variant this IDN is:
      registered, reserved, blocked or canonical; see Section 6.6.1

   o  An <idnTableId> element that references the IDN Table used for the
      IDN.  This corresponds to the "id" attribute of the <idnTableRef>
      element.

   o  An OPTIONAL <roid> element that contains the ROID of the
      corresponding domain object, if there is one.  It MUST be provided
      if the domain object exists.

   o  A <canonicalRoid> element that contains the ROID of the canonical
      domain name.  It MUST be provided if the IDN is NOT the canonical
      domain name.

   o  An OPTIONAL <extension> element that allows extending the IDN
      object.

   Example of <idn> object:


   ...
   <rdeIDN:idn>
       <rdeIDN:aName>xn--pingino-q2a.test</rdeIDN:aName>
       <rdeIDN:uName>pingueino.test</rdeIDN:uName>

6.7.  RDE EPP Parameters object

   An OPTIONAL <eppParams> element contains some EPP parameters that may
   be helpful when rebuilding a registry from the escrow deposits.  The
   element SHOULD be included in Deposits if the registry uses EPP.

   The syntax and content of the <eppParams> children elements is as
   explained in section 2.4 of [RFC5730].  The children of the
   <eppParams> are as follows:

   o  One or more <version> elements that indicate the EPP versions
      supported by the registry.

   o  One or more <lang> elements that indicate the identifiers of the
      text response languages supported by the registry's EPP server.

   o  One or more <objURI> elements that contain namespace URIs
      representing the objects that the registry's EPP server is capable
      of managing.

   o  An OPTIONAL <svcExtension> element that contains one or more
      <extURI> elements that contain namespace URIs representing object
      extensions supported by the registry's EPP server.

   o  A <dcp> element that contains child elements used to describe the
      server's privacy policy for data collection and management.  See
      section 2.4 of [RFC5730] for more details.

Internet-Draft           Domain Name Data Escrow              March 2011


7.  Formal Syntax

   Seven schemas are presented here.  The first schema is the base RDE
   schema.  The second schema defines domain object for RDE.  The third
   schema defines host object for RDE.  The fourth schema defines
   contact object for RDE.  The fifth schema defines registrar object
   for RDE.  The sixth schema defines the idnTableRef and IDN objects.
   The last schema defines the eppParams objects.

8.  Extension Guidelines

   TBD


9.  Internationalization Considerations

   Data Escrow deposits are represented in XML, which provides native
   support for encoding information using the Unicode character set and
   its more compact representations including UTF-8.  Conformant XML
   processors recognize both UTF-8 and UTF-16.  Though XML includes
   provisions to identify and use other character encodings through use
   of an "encoding" attribute in an <?xml?> declaration, use of UTF-8 is
   RECOMMENDED.


10.  IANA Considerations

   This document uses URNs to describe XML namespaces and XML schemas
   conforming to a registry mechanism described in [RFC3688].  Fourteen
   URI assignments have been registered by the IANA.

   Registration request for the RDE namespace:

      URI: urn:ietf:params:xml:ns:rde-1.0

      Registrant Contact: See the "Author's Address" section of this
      document.

      XML: None.  Namespace URIs do not represent an XML specification.

   Registration request for the RDE XML schema:

11.  Security Considerations

   This specification does not define the security mechanisms to be used
   in the transmission of the data escrow deposits, since it only
   specifies the minimum necessary to enable the rebuilding of a
   Registry from deposits without intervention from the original
   Registry.

   Depending on local policies, some elements or most likely, the whole
   deposit will be considered confidential.  As such the Registry
   transmitting the data to the Escrow Agent SHOULD take all the
   necessary precautions like encrypting the data itself and/or the
   transport channel to avoid inadvertent disclosure of private data.

   It is also of the utmost importance the authentication of the parties
   passing data escrow deposit files.  The Escrow Agent SHOULD properly
   authenticate the identity of the Registry before accepting data
   escrow deposits.  In a similar manner, the Registry SHOULD
   authenticate the identity of the Escrow Agent before submitting any
   data.

   Additionally, the Registry and the Escrow Agent SHOULD use integrity
   checking mechanisms to ensure the data transmitted is what the source
   intended.  Validation of the contents by the Escrow Agent is
   RECOMMENDED to ensure not only the file was transmitted correctly
   from the Registry, but also the contents are also "meaningful".
