Internet-Draft            Registry Data Escrow                 July 2010


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 contracted third party called
   an Escrow Agent.  These deposits comprise all the data needed to
   resume operations if the registration organization could not function
   as a result of a catastrophe or a financial situation.  For a domain
   name registry or registrar the data to be deposited would include all
   the objectes related to registered domain names, e.g., contacts, name
   servers, etc.

   The purpose of data escrow is to permit quick resumption of
   registration service by another registration organization after a
   catastrophe.  The goal is higher resiliency of registration services,
   for the benefit of Internet users.  The beneficiaries of a registry
   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
   such a requirement for ICANN's generic top-level domain accredited
   registrars.

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


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.

   ESCROW AGENT.  The organization contracted 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 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 directl or through and affiliate company) provides
   Registry services to 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 receipt of data from registrars concerning
   registrations of domain names and name servers; provision to
   registrars of status information relating to the DNS servers for the
   RCDN; dissemination of RCDN zone files; operation of the Registry DNS
   servers; and dissemination of 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.

3.  Problem Scope

   Since a few years ago, the issue of Registry continuity has been
   carefully considered in the gTLD and ccTLD space.  Various
   organizations have made 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 also anticipated that more Registries will
   be implementing Escrow especially with the advent of the new gTLD
   program.

   Now, it would seem benefitial to have a standardized specification
   for Registry Data Escrow that can be used by any Registry to submit
   its Deposits and, in case, to use those deposits to operate Registry
   Services for a RCDN that has to be transitioned of Registry operator.

   A solution to the problem at hand SHALL clearly identify the format
   and contents of the Deposits a Registry has to make, such that
   another different Registry would be able to rebuild the Registry
   Services of the former, without its help, in a timely manner, with
   minimum harm to the 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 those objects of
   such delicate confidentiality that it is best to leave them out of
   the Deposits, 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 whether
   to use Registry Data Escrow are outside of scope of this document.

4.  General Conventions

4.1.  Dates

   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 with no offset from the zero meridian, as
   specified in [RFC3339].

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 Domain 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.
   Format is based on EPP [RFC5730] and related RFCs by Scott
   Hollenbeck.

5.1.  Root element <escrowDeposit>

   The container or root element for a Registry Data Escrow deposits is
   <escrowDeposit>.  This element contains the following child elements:
   summary, contents and deletes.  This element also contains que
   following attributes:

Internet-Draft            Registry Data Escrow                 July 2010


   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 by a differential deposit "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.

   Example of root element object:

   <?xml version="1.0" encoding="UTF-8" standalone="no"?>
   <rde:escrowDeposit
       xmlns:rde="urn:ietf:params:xml:ns:rde-1.0"

       </rde:contents>
       <rde:deletes>
          ...
       </rde:deletes>
   </rde:escrowDeposit>

5.2.  Child <summary> element

   This element contains the following child elements:

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

   o  A <contentsCount> element contains four child elements:
      <contactCount>, <hostCount>, <domainCount> and <registrarCount>
      that identify the number of objects contained in the "contents"
      section.  This element MAY also contain and extension element
      allowing extending the format.

   o  A <deletesCount> element ontains four elements: <contactCount>,
      <hostCount>, <domainCount> and <registrarCount> that identify the
      number of objects contained in the "deletes" section.  This
      element MAY also contain and extension element allowing extending
      the format.

   Example of <summary> element object:

           <rde:contentsCount>
               <rde:contactCount>1234</rde:contactCount>
               <rde:hostCount>123456</rde:hostCount>
               <rde:domainCount>123456</rde:domainCount>
               <rde:registrarCount>123</rde:registrarCount>
           </rde:contentsCount>
           <rde:deletesCount>

           </rde:deletesCount>
       </rde:summary>
       ...
   </rde:escrowDeposit>

5.3.  Child <contents> element

   This section of the deposit contains the actual objects in the
   deposit.  It MAY contain: contacts, hosts, domains and registrars as
   defined in Section 6.  This element MAY also contain and extension
   element allowing extending the format.

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

5.4.  Child <deletes> element

   This section SHOULD only be present in deposits of type Incremental
   or Differential.  It contains the list of objects that were delete
   since the base previous deposit.  Each object in this section
   contains an ID for the object deleted.  For domains and hosts it will
   be the fully qualified domain name.

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

   Elements that MAY appear in this section are: delContact, delHost,
   delDomain and/or delRegistrar.  It MAY also contain and extension
   element allowing extending the format.

6.  Object Description

   This section describes the base objects defined in EPP: domains,
   hosts and objects with the addition of registrars.

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 delDomain 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]).

   Example of domain object:

6.2.  RDE Host Object

   The RDE host object is based on the EPP host name mapping in
   [RFC5732].  There are two elements used in this format related to
   hosts: the host object per se, used inside the <contents> element and
   the delHost object used inside the <deletes> element.

6.2.1.  <host> object

   The RDE domain object is based on the EPP host <info> response for an
   authorized client (see Section 3.1.2. of [RFC5732]).

   Example of <host> object:

   ...
   <rde:host
       xmlns:rdeHost="urn:ietf:params:xml:ns:rdeHost-1.0">

6.3.  RDE Contact Object

   The RDE contact object is based on the EPP contact name mapping in
   [RFC5733].  There are two elements used in this format related to
   contacts: the contact object per se, used inside the <contents>
   element and the delContact object used inside the <deletes> element.

6.3.1.  <contact> object

   The contact object is based on the EPP contact <info> response for an
   authorized client (see Section 3.1.2. of [RFC5733]).

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 delRegistrar 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.

   o  A <company> element that contains the name of the company.

   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
      contains the following child elements:

      *  An OPTIONAL <org> element that contains the name of the
         organization with which the registrar is affiliated.

      *  A <addr> element that contains address information associated
         with the registrar.  The <addr> element contains the following
         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.

         +  An OPTIONAL <pc> element that contains the registrar's
            postal code.

         +  A <cc> element that contains the registrar's country code.

   o  An OPTIONAL <voice> element that contains the registrar's voice
      telephone number.

   o  An OPTIONAL <fax> element that contains the registrar's facsimile
      telephone number.

   o  A <email> element that contains the registrar's email address.

   o  A <url> element that contains the registrar's URL.

   o  One or more OPTIONAL <contact> elements that contain identifiers
      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.

   Example of <registrar> object:

7.  Formal Syntax

   Five 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.
