Internet-Draft          EPP Domain Name Mapping        November 10, 2000


1. Introduction

  This document describes an internet domain name mapping for version
  1.0 of the Extensible Provisioning Protocol (EPP).  This mapping is
  specified using the Extensible Markup Language (XML) 1.0 as described
  in [XML] and XML Schema notation as described in [XML-SD] and [XML-
  SS].

  The referenced XML Schema documents recently progressed from Working
  Draft status to Candidate Recommendation status.  The references to
  these documents and the URIs used to refer to XML Schema namespaces
  MUST be changed once XML parsers that support the updated
  specifications are available.

  [EPP] provides a complete description of EPP command and response
  structures.  A thorough understanding of the base protocol
  specification is necessary to understand the mapping described in this
  document.

  It is important to note that XML is case sensitive.  XML
  specifications and examples provided in this document MUST be
  interpreted in the exact character case presented to develop a
  conforming implementation.

  This document is being discussed on the "rrp" mailing list.  To join
  the list, send a message to <majordomo@NSIRegistry.net> with the words
  "subscribe rrp" in the body of the message.  There is a web site for
  the list archives at <http://www.NSIRegistry.net/maillist/rrp>.

2. Object Attributes

  An EPP domain object has attributes and associated values that may be
  viewed and modified by the sponsoring client or the server.  This
  section describes each attribute type in detail.

2.1 Domain Name and Host Names

  The syntax for domain and host names described in this document MUST
  conform to [RFC952] as updated by [RFC1123].  These conformance
  requirements MAY change as a result of progressing work in developing
  standards for internationalized domain names.  A server MAY restrict
  allowable domain names to a particular top level domain, second level
  domain, or other domain for which the server is authoritative.

2.2 Client Identifiers

  All EPP clients are identified by a server-unique identifier.  Client
  identifiers use the contact identifier syntax described in [EPP-C].

2.3 Status Values

  A domain name always has at least one associated status indicator.
  Status indicators MAY be set only by the client that sponsors a known
  domain object and by the server on which the object resides.  A client
  MAY change the status of a domain object using the EPP <update>
  command.

  Client-Managed Status Values:

  CLIENT-HOLD

  The domain MUST NOT be published in a zone for DNS resolution.

  CLIENT-LOCK

  The domain MUST NOT be modified through any action of the EPP
  <create>, <transfer>, or <update> commands, though the <update>
  command MAY be used to change the status value.  The <renew> command
  MAY be applied to avoid exceeding the end of the domain validity
  period.  Child objects MUST NOT be added or removed.

  Server-Managed Status Values:

  NEW

  The domain has been delegated, can be modified, and has not been
  published in a zone.

Internet-Draft          EPP Domain Name Mapping        November 10, 2000


  ACTIVE

  The domain has been delegated, can be modified, and appears in a zone.

  INACTIVE

  The domain has not been delegated, can be modified, and does not
  appear in a zone.

  HOLD

  The domain MUST NOT be published in a zone for DNS resolution.

  LOCK

  The domain MUST NOT be modified through any action of the EPP
  <create>, <transfer>, or <update> commands, though the <update>
  command MAY be used to change the status value.  The <renew> command
  MAY be applied to avoid exceeding the end of the domain validity
  period.  Child objects MUST NOT be added or removed.

  PENDING-TRANSFER

  A transfer request has been received for the domain, and processing of
  the request is pending.

  PENDING-DELETE

  A delete request has been received for this domain.  The domain has
  been removed from the zone, but has not yet been purged from the
  server database.

2.4 Domain Contacts

  The syntax for domain contact identifiers is described in [EPP-C].  A
  server MAY support a contact object service to allow contact objects
  to be associated with domain objects.

2.5 Dates and Times

  Date and time attribute values MUST be represented in Universal
  Coordinated Time (UTC). Both extended and truncated date and time
  forms defined in [ISO8601] MAY be used.

  Every domain name has an associated validity period.  The validity
  period is determined when a domain object is created, and it MAY be
  extended by the action of the EPP <renew> and <transfer> commands.  If
  the end of the validity period is reached without explicit client

  action to extend the period, a server MAY extend the period
  automatically for one additional year or it MAY place the domain on
  HOLD status.  A domain name MUST NOT be deleted automatically upon
  expiration of the validity period.

2.6 Authorization Identifiers

  Authorization identifiers are associated with domain name objects to
  facilitate authorization of transfer requests.  Authorization
  identifiers use the transaction identifier syntax described in [EPP].

3. EPP Command Mapping

  A detailed description of the EPP syntax and semantics can be found in
  [EPP].  The command mappings described here are specifically for use
  in provisioning and managing internet domain names via EPP.

3.1 EPP Query Commands

  EPP provides three commands to retrieve domain information: <info> to
  retrieve detailed information associated with a domain, <ping> to
  determine if a domain is known to the server, and <transfer> to
  retrieve domain transfer status information.

3.1.1 EPP <info> Command

  The EPP <info> command is used to retrieve information associated with
  a domain.  In addition to the standard EPP command elements, the
  <info> command MUST contain a <domain:info> element that identifies
  the domain namespace and the location of the domain schema.  The
  <domain:info> element MUST contain the following child elements:

  - A <domain:name> element that contains the fully qualified domain
  name for which information is requested.

  Example <info> command:

  C:<?xml version="1.0" standalone="no"?>
  C:<epp xmlns="urn:iana:xmlns:epp"
  C:     xmlns:xsi="http://www.w3.org/1999/XMLSchema-instance"
  C:     xsi:schemaLocation="urn:iana:xmlns:epp epp.xsd">
  C:  <command>
  C:    <info>
  C:      <domain:info xmlns:domain="urn:iana:xmlns:domain"
  C:       xsi:schemaLocation="urn:iana:xmlns:domain domain.xsd">
  C:        <domain:name>example.com</domain:name>
  C:      </domain:info>
  C:    </info>
  C:    <trans-id>
  C:      <date>2000-06-08</date>
  C:      <client-id>ClientX</client-id>
  C:      <code>ABC-12345-XYZ</code>
  C:    </trans-id>
  C:  </command>
  C:</epp>

  If the domain is known to the server, the EPP <response-data> element
  MUST contain a child <domain:info-data> element that identifies the
  domain namespace and the location of the domain schema.  The

Internet-Draft          EPP Domain Name Mapping        November 10, 2000


  <domain:info-data> element SHALL contain the following child elements:

  - A <domain:name> element that contains the fully qualified name of
  the domain.

  - A <domain:client-id> element that contains the identifier of the
  sponsoring client.

  - One or more <domain:status> elements that contain the current status
  descriptors associated with the domain.  See the <update> command
  description for a list of valid status values.

  - If supported by the server, one or more <domain:contact> elements
  that contain identifiers for the registrant, administrative,
  technical, and billing contacts.

  - Zero or more <domain:server> elements that contain the fully
  qualified names of the name servers to which the domain is delegated.

  - Zero or more <domain:child-server> elements that contain the fully
  qualified names of the child name servers known under this parent
  domain.

  - A <domain:created-by> element that contains the identifier of the
  client that created the domain name.

  - A <domain:created-date> element that contains the date and time of
  domain creation.

  - A <domain:expiration-date> element that contains the date and time
  identifying the end of the domain's registration period.

  - A <domain:last-updated-by> element that contains the identifier of
  the client that last updated the domain name.  This element MUST NOT
  be present if the domain has never been modified.

  - A <domain:last-updated-date> element that contains the date and time
  of the most recent domain modification.  This element MUST NOT be
  present if the domain has never been modified.

  - A <domain:last-transfer-date> elements that contains the date and
  time of the most recent successful transfer.  This element MUST NOT be
  provided if the domain has never been transferred.

  - A <domain:auth-id> elements derived from either the original
  creation transaction or the most recent successful transfer
  transaction.  This element MUST NOT be provided if the querying client
  is not the current sponsoring client.

  S:</epp>

  An EPP error response MUST be returned if an <info> command could not
  be processed for any reason.

3.1.2 EPP <ping> Command

  The EPP <ping> command is used to determine if a domain name is known
  to the server.  In addition to the standard EPP command elements, the
  <ping> command MUST contain a <domain:ping> element that identifies
  the domain namespace and the location of the domain schema.  The
  <domain:ping> element MUST contain the following child elements:

  - One or more (up to a maximum of sixteen) <domain:name> elements that
  contain the fully qualified name of the queried domains.

  Example <ping> command:

  C:<?xml version="1.0" standalone="no"?>
  C:<epp xmlns="urn:iana:xmlns:epp"
  C:     xmlns:xsi="http://www.w3.org/1999/XMLSchema-instance"

  When a <ping> command has been processed successfully, the EPP
  <response-data> element MUST contain a child <domain:ping-data>
  element that identifies the domain namespace and the location of the
  domain schema.  The <domain:ping-data> element SHALL contain the
  following child elements:

  - One or more (up to a maximum of sixteen) <domain:name> elements that
  contain the fully qualified name of the queried domains and a "result"
  attribute whose value identifies the object as either "known" or

  An EPP error response MUST be returned if a <ping> command could not
  be processed for any reason.

3.1.3 EPP <transfer> Command

  The EPP <transfer> command provides a query operation that allows a
  client to determine real-time status of pending and completed transfer
  requests.  In addition to the standard EPP command elements, the
  <transfer> command MUST contain an "op" attribute with value "query",
  and a <domain:transfer-query> element that identifies the domain
  namespace and the location of the domain schema.  The
  <domain:transfer-query> element MUST contain the following child
  elements:

  - A <domain:name> element that contains the fully qualified name of
  the domain.

  When a <transfer> command has been processed successfully, a server
  MUST respond with an EPP <response-data> element that MUST contain a
  child <domain:transfer-data> element that identifies the domain
  namespace and the location of the domain schema.  The
  <domain:transfer-data> element SHALL contain the following child
  elements:

  - A <domain:name> element that contains the fully qualified domain
  name used in the query.

  - A <domain:request-client> element that contains the identifier of
  the client that initiated the transfer request.

  - A <domain:action-client> element that contains the identifier of the
  client that SHOULD respond to the transfer request.

  - A <domain:transfer-status> element that contains the state of the
  most recent transfer request.  Valid values are "PENDING", "APPROVED",
  "REJECTED", "AUTO-APPROVED", "AUTO-REJECTED", and "CANCELLED".

  - A <domain:request-date> element that contains the date and time that

  the transfer was requested.

  - A <domain:action-date> element that contains the date and time of a
  required or completed response.  For a PENDING request, the value
  identifies the date and time by which a response is required before an
  automated response action MUST be taken by the server.  For all other
  status types, the value identifies the date and time when the request
  was completed.

  - An OPTIONAL <domain:expiration-date> element that contains the end
  of the domain's validity period if the <transfer> command caused or
  causes a change in the validity period.

  An EPP error response MUST be returned if a <transfer> query command
  could not be processed for any reason.

3.2 EPP Transform Commands

  EPP provides five commands to transform domain object information:
  <create> to create an instance of a domain object, <delete> to delete
  an instance of a domain object, <renew> to extend the validity period
  of a domain object, <transfer> to manage domain object sponsorship
  changes, and <update> to change information associated with a domain
  object.

3.2.1 EPP <create> Command

  The EPP <create> command provides a transform operation that allows a
  client to create a domain object.  In addition to the standard EPP
  command elements, the <create> command MUST contain a <domain:create>
  element that identifies the domain namespace and the location of the
  domain schema.  The <domain:create> element MUST contain the following
  child elements:

  - A <domain:name> element that contains the fully qualified domain
  name of the object to be created.

  - An OPTIONAL <domain:period> element that contains the initial
  registration period of the domain, measured in years.  If not
  specified, the initial registration period MUST be one year.  The
  minimum allowable value is one (1) year.  The maximum allowable value
  is ninety-nine (99) years.  A server MAY support a lower maximum
  value.

  - Zero or more (up to a maximum of thirteen) <domain:server> elements
  that contain the fully qualified host name of a known host object to
  provide resolution services for the domain.  A host object MUST be
  known to the server before a domain can be delegated to the host.  A
  server MUST provide host object services to provide domain name
  services.  The EPP mapping for host objects is described in [EPP-H].

  - Zero or more (up to a maximum of four) <domain:contact> elements
  that contain the registrant, administrative, technical, and billing
  contact identifiers to be associated with the domain.  A contact
  identifier MUST be known to the server before the contact can be
  associated with the domain.  Only one contact identifier of each type
  MAY be specified.  A server MAY provide contact object services when
  providing domain name object services.  The EPP mapping for contact
  objects is described in [EPP-C].

  It is important to note that the transaction identifier associated

  with successful creation of a domain object becomes the authorization
  identifier required to transfer sponsorship of the domain object.  A
  client MUST retain all transaction identifiers associated with domain
  object creation and protect them from disclosure.  A client MUST also
  provide a copy of the transaction identifier information to the domain
  registrant, who will need this information to request a domain
  transfer through a different client.

  Example <create> command:

  C:<?xml version="1.0" standalone="no"?>

  C:      <code>ABC-12345-XYZ</code>
  C:    </trans-id>
  C:  </command>
  C:</epp>

  When a <create> command has been processed successfully, a server MUST
  respond with an EPP <response-data> element that MUST contain a child
  <domain:expire-data> element that identifies the domain namespace and
  the location of the domain schema.  The <domain:expire-data> element
  SHALL contain the following child elements:

  - A <domain:name> element that contains the fully qualified domain
  name that has been created.

  - A <domain:expiration-date> element that contains the end of the
  domain's validity period.

  An EPP error response MUST be returned if a <create> command could not
  be processed for any reason.

3.2.2 EPP <delete> Command

  The EPP <delete> command provides a transform operation that allows a
  client to delete a domain object.  In addition to the standard EPP
  command elements, the <delete> command MUST contain a <domain:delete>
  element that identifies the domain namespace and the location of the
  domain schema.  The <domain:delete> element SHALL contain the
  following child elements:

  - A <domain:name> element that contains the fully qualified domain
  name of the object to be deleted.

  A domain name MUST NOT be deleted if the domain is associated with
  child name servers.  For example, if domain "example.com" is known,
  and name server "ns1.example.com" is also known, then domain
  "example.com" MUST NOT be deleted until server "ns1.example.com" has
  been either deleted or renamed to exist in a different parent domain.

  The EPP <renew> command provides a transform operation that allows a
  client to extend the validity period of a domain object.  In addition
  to the standard EPP command elements, the <renew> command MUST contain
  a <domain:renew> element that identifies the domain namespace and the
  location of the domain schema.  The <domain:renew> element SHALL
  contain the following child elements:

  - A <domain:name> element that contains the fully qualified domain
  name of the object whose validity period is to be extended.

  - A <domain:current-expiration-year> element that contains the year in
  which the current validity period ends.  This value ensures that
  repeated <renew> commands do not result in multiple unanticipated
  successful renewals.

  - A <domain:period> element that contains the number of years to be
  added to the validity period of the domain.  The minimum allowable
  value is one (1) year.  The maximum allowable value is ninety-nine
  (99) years.  A server MAY support a lower maximum value.

  - A <domain:name> element that contains the fully qualified domain
  name of the object for which a transfer request is to be created,
  approved, rejected, or cancelled.

  - An OPTIONAL <domain:period> element that contains a number of years
  to be added to the registration period of the domain if the transfer
  is successful.  If not specified, the registration period MUST NOT be
  changed as a result of the transfer.  The minimum allowable value is
  one (1) year.  The maximum allowable value is ninety-nine (99) years.
  A server MAY support a lower maximum value.  This element MUST be
  consistently present or absent for all associated request, approval,
  rejection, or cancellation operations.

  Every EPP <transfer> command MUST contain an "op" attribute that
  identifies the transfer operation to be performed.  Valid values,
  definitions, and authorizations for all attribute values are defined
  in [EPP].

  Every EPP <transfer> command MUST also contain an authorization
  identifier as described in [EPP].  It is important to note that the
  transaction identifier associated with successful transfer of a domain
  object becomes the authorization identifier required to authorize
  subsequent transfers of sponsorship of the domain object.  A client
  MUST retain all transaction identifiers associated with successful
  domain object transfers and protect them from disclosure.  A client

  name of the object to be updated.

  - An OPTIONAL <domain:add> element that contains attribute values to

  - An OPTIONAL <domain:remove> element that contains attribute values
  to be removed from the domain object.

  Either a <domain:add> element or a <domain:remove> element MUST be
  provided.  The <domain:add> and <domain:remove> elements SHALL contain
  the following child elements:

  - Zero or more <domain:server> elements that contain the fully
  qualified host name of a known host object.  A host object MUST be
  known to the server before a server attribute can be added or removed
  from a domain object.  The EPP mapping for host objects is described
  in [EPP-H].

  - Zero or more (up to a maximum of four) <domain:contact> elements
  that contain the registrant, administrative, technical, and billing
  contact identifiers to be associated with the domain.  A contact
  identifier MUST be known to the server before the contact can be
  associated with the domain.  Only one contact identifier of each type
  MAY be specified.  A server MAY provide contact object services when
  providing domain name object services.  The EPP mapping for contact
  objects is described in [EPP-C].

  - One or two <domain:status> elements that contain status values to be
  applied to or removed from the domain object.

  It is important to note that the maximum number of domain attribute
  elements is subject to the number of values currently associated with
  the domain object.  For example, if a domain object currently has "n"
  server attribute elements, the maximum number of server attribute
  elements that can be added is 13 - "n".  Likewise, the maximum number
  of contact elements that can be added is 4 - "n", with the added
  restriction that only one contact of each type (registrant,
  administrative, technical, or billing) MAY be associated with a domain
  object.

5. Internationalization Considerations

  EPP is represented in XML, which provides native support for encoding
  information using the double-byte Unicode character set and its more
  compact representations including UTF-8.  Compliant XML processors are
  required to understand both UTF-8 and raw Unicode character sets; XML
  also includes a provision for identifying other character sets through
  use of an "encoding" attribute in an <?xml?> processing instruction.
  The complete list of character set encoding identifiers is maintained
  by IANA and is described in [CHARSET] and [RFC1700].

  All date-time values presented via EPP MUST be expressed in Universal
  Coordinated Time.  The XML Schema "date" format allows use of time
  zone identifiers to indicate offsets from the zero meridian, but this
  option MUST NOT be used within EPP.  Both extended and truncated date
  and time forms defined in [ISO8601] MAY be used.

  This document requires domain and host name syntax as specified in
  [RFC952] as updated by [RFC1123].  These conformance requirements MAY
  change as a result of progressing work in developing standards for
  internationalized domain names.

6. IANA Considerations

  XML schemas require a URI for unique identification.  Schemas MUST be
  registered to ensure URI uniqueness, but the IETF does not currently
  have a recommended repository for the registration of XML schemas.
  This document uses URNs to describe XML namespaces and XML schemas.
  IANA SHOULD maintain a registry of XML namespace and schema URI
  assignments.  Per policies described in [IANA], URI assignment
  requests SHOULD be reviewed by a designated expert, and values SHOULD
  be assigned only as a result of standards action taken by the IESG.

7. Security Considerations

  The object mapping described in this document does not provide any
  security services beyond those specified by [EPP].
