Introduction This document describes a personal and organizational identifier 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 [XMLS-1] and [XMLS-2]. [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. XML is case sensitive. Unless stated otherwise, XML specifications and examples provided in this document MUST be interpreted in the character case presented to develop a conforming implementation. This document is being discussed on the "ietf-provreg" mailing list. To join the list, send a message to with the words "subscribe ietf-provreg" in the body of the message. There is a web site for the list archives at http://www.cafax.se/ietf-provreg. Hollenbeck Expires July 24, 2002 [Page 3] Internet-Draft EPP Contact mapping January 24, 2002 2. Object Attributes An EPP contact object has attributes and associated values that can be viewed and modified by the sponsoring client or the server. This section describes each attribute type in detail. The formal syntax for the attribute values described here can be found in the "Formal Syntax" section of this document and in the appropriate normative references. 2.1 Contact and Client Identifiers All EPP contacts are identified by a server-unique identifier. Contact identifiers are character strings with a specified minimum length, a specified maximum length, and a specified format. Contact identifiers use the "clIDType" client identifier syntax described in [EPP]. 2.2 Status Values A contact object MUST always have at least one associated status value. Status values can be set only by the client that sponsors a contact object and by the server on which the object resides. A client can change the status of a contact object using the EPP command. Each status value MAY be accompanied by a string of human-readable text that describes the rationale for the status applied to the object. A client MUST NOT alter status values set by the server. A server MAY alter or override status values set by a client subject to local server policies. Status values that can be added or removed by a client are prefixed with "client". Corresponding status values that can be added or removed by a server are prefixed with "server". Status values that do not begin with either "client" or "server" are server-managed. Status Value Descriptions: clientDeleteProhibited, serverDeleteProhibited Requests to delete the object MUST be rejected. clientTransferProhibited, serverTransferProhibited Requests to transfer the object MUST be rejected. clientUpdateProhibited, serverUpdateProhibited Hollenbeck Expires July 24, 2002 [Page 4] Internet-Draft EPP Contact mapping January 24, 2002 Requests to update the object (other than to remove this status) MUST be rejected. linked The contact object has at least one active association with another object, such as a domain object. Servers SHOULD provide services to determine existing object associations. ok This is the nominal status value for an object that has no pending operations or prohibitions. pendingDelete A delete request has been received for the object, but the object has not yet been purged from the server database. pendingTransfer A transfer request has been received for the object, and completion of the request is pending. Transform commands other than MUST be rejected while an object is in this state. "ok" status MAY only be combined with "linked" status. "linked" status MAY be combined with any status. "pendingDelete" status MUST NOT be combined with either "clientDeleteProhibited" or "serverDeleteProhibited" status. "pendingTransfer" status MUST NOT be combined with either "clientTransferProhibited" or "serverTransferProhibited" status. All other status value combinations are valid. 2.3 Individual and Organizational Names Individual and organizational names associated with a contact are represented using character strings. These strings have a specified minimum length and a specified maximum length. Individual and organizational names MAY be provided in both UTF-8 [RFC2279] and a subset of UTF-8 that can be represented in 7-bit ASCII depending on local needs. 2.4 Address Every contact has associated postal address information. A postal address contains OPTIONAL street information, city information, OPTIONAL state/province information, an OPTIONAL postal code, and a country identifier. Address information MAY be provided in both UTF-8 Hollenbeck Expires July 24, 2002 [Page 5] Internet-Draft EPP Contact mapping January 24, 2002 and a subset of UTF-8 that can be represented in 7-bit ASCII depending on local needs. 2.4.1 Street, City, and State or Province Contact street, city, and state or province information is represented using character strings. These strings have a specified minimum length and a specified maximum length. 2.4.2 Postal Code Contact postal codes are represented using character strings. These strings have a specified minimum length and a specified maximum length. 2.4.3 Country Contact country identifiers are represented using two-character identifiers specified in [ISO3166]. 2.5 Telephone Numbers Contact telephone number structure is derived from structures defined in [E164a]. Telephone numbers described in this mapping are character strings that MUST begin with a plus sign ("+", ASCII value 0x002B), followed by a country code defined in [E164b], followed by a dot (".", ASCII value 0x002E), followed by a sequence of digits representing the telephone number. An optional "x" attribute is provided to note telephone extension information. 2.6 Email Addresses Email address syntax is defined in [RFC2822]. This mapping does not prescribe minimum or maximum lengths for character strings used to represent email addresses. 2.7 Dates and Times Date and time attribute values MUST be represented in Universal Coordinated Time (UTC) using the Gregorian calendar. The extended date-time form defined in [DATE-TIME] MUST be used to represent date- time values as XML Schema does not support truncated date-time forms. 2.8 Authorization Information Authorization information is associated with contact objects to facilitate transfer operations. Authorization information is assigned when a contact object is created, and it might be updated in the Hollenbeck Expires July 24, 2002 [Page 6] Internet-Draft EPP Contact mapping January 24, 2002 future. This specification describes password-based authorization information, though other mechanisms are possible. Hollenbeck Expires July 24, 2002 [Page 7] Internet-Draft EPP Contact mapping January 24, 2002 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 contact objects via EPP. 3.1 EPP Query Commands EPP provides three commands to retrieve contact information: to determine if a contact object can be provisioned within a repository, to retrieve detailed information associated with a contact object, and to retrieve contact object transfer status information. 3.1.1 EPP Command The EPP command is used to determine if an object can be provisioned within a repository. It provides a hint that allows a client to anticipate the success or failure of provisioning an object using the command. Object availability and provisioning conditions are a matter of server policy. In addition to the standard EPP command elements, the command MUST contain a element that identifies the contact namespace and the location of the contact schema. The element contains the following child elements: - One or more elements that contain the server-unique identifier of the contact objects to be queried. Hollenbeck Expires July 24, 2002 [Page 8] Internet-Draft EPP Contact mapping January 24, 2002 Example command: C: C: C: C: C: C: sh8013 C: sah8013 C: 8013sah C: C: C: ABC-12345 C: C: When a command has been processed successfully, the EPP element MUST contain a child element that identifies the contact namespace and the location of the contact schema. The element contains one or more elements that contain the following child elements: - A element that identifies the queried object. This element MUST contain an "avail" attribute whose value indicates object availability at the moment the command was completed. A value of "1" or "true" means that the object is available. A value of "0" or "false" means that the object is not available. - An OPTIONAL element that MAY be provided when an object is not available for provisioning. If present, this element contains server-specific text to help explain why the object is unavailable. This text MUST be represented in the response language previously negotiated with the client; an OPTIONAL "lang" attribute MAY be present to identify the language if the negotiated value is something other than the default value of "en" (English).

In addition to the standard EPP command elements, the command MUST contain a element that identifies the contact namespace and the location of the contact schema. The element contains the following child elements: Hollenbeck Expires July 24, 2002 [Page 10] Internet-Draft EPP Contact mapping January 24, 2002 - A element that contains the server-unique identifier of the contact object to be queried. Example command: C: C: C: C: C: C: sh8013 C: C: C: ABC-12345 C: C: When an command has been processed successfully, the EPP element MUST contain a child element that identifies the contact namespace and the location of the contact schema. The element contains the following child elements: - A element that contains the server-unique identifier of the contact object. - A element that contains the Repository Object IDentifier assigned to the contact object when the object was created. - One or more elements that describe the status of the contact object. - One or two elements that contain postal address information. Two elements are provided so that address information can be provided in both internationalized and localized forms. If an internationalized form is provided, it MUST be listed first and 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 is provided, element content MAY be represented in unrestricted UTF-8. The element contains the following child elements: Hollenbeck Expires July 24, 2002 [Page 11] Internet-Draft EPP Contact mapping January 24, 2002 - A element that contains the name of the individual or role represented by the contact. - An OPTIONAL element that contains the name of the organization with which the contact is affiliated. - A element that contains address information associated with the contact. A element contains the following child elements: - One, two, or three OPTIONAL elements that contain the contact's street address. - A element that contains the contact's city. - An OPTIONAL element that contains the contact's state or province. - An OPTIONAL element that contains the contact's postal code. - A element that contains the contact's country code. - An OPTIONAL element that contains the contact's voice telephone number. - An OPTIONAL element that contains the contact's facsimile telephone number. - A element that contains the contact's email address. - A element that contains the identifier of the sponsoring client. - A element that contains the identifier of the client that created the contact object. - A element that contains the date and time of contact object creation. - A element that contains the identifier of the client that last updated the contact object. This element MUST NOT be present if the contact has never been modified. - A element that contains the date and time of the most recent contact object modification. This element MUST NOT be present if the contact object has never been modified. Hollenbeck Expires July 24, 2002 [Page 12] Internet-Draft EPP Contact mapping January 24, 2002 - A elements that contains the date and time of the most recent successful contact object transfer. This element MUST NOT be provided if the contact object has never been transferred. - A element that contains authorization information associated with the contact object. This element MUST NOT be provided if the querying client is not the current sponsoring client.

In addition to the standard EPP command elements, the command MUST contain an "op" attribute with value "query", and a element that identifies the contact namespace and the location of the contact schema. The element MUST contain the following child elements: - A element that contains the server-unique identifier of the contact object to be queried. - A element that contains authorization information associated with the contact object. Hollenbeck Expires July 24, 2002 [Page 14] Internet-Draft EPP Contact mapping January 24, 2002 Example query command: C: C: C: C: C: C: sh8013 C: 2fooBAR C: C: C: ABC-12345 C: C: When a query command has been processed successfully, the EPP element MUST contain a child element that identifies the contact namespace and the location of the contact schema. The element contains the following child elements: - A element that contains the server-unique identifier for the queried contact. - A element that contains the state of the most recent transfer request. - A element that contains the identifier of the client that requested the object transfer. - A element that contains the date and time that the transfer was requested. - A element that contains the identifier of the client that SHOULD act upon the transfer request. - A 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 SHOULD be taken by the server. For all other status types, the value identifies the date and time when the Hollenbeck Expires July 24, 2002 [Page 15] Internet-Draft EPP Contact mapping January 24, 2002 request was completed. Example query response: S: S: S: S: S: Command completed successfully S: S: S: S: sh8013 S: pending S: ClientX S: 2000-06-06T22:00:00.0Z S: ClientY S: 2000-06-11T22:00:00.0Z S: S: S: S: ABC-12345 S: 54322-XYZ S: S: S: An EPP error response MUST be returned if a query command can not be processed for any reason. 3.2 EPP Transform Commands EPP provides four commands to transform contact object information: to create an instance of a contact object, to delete an instance of a contact object, to manage contact object sponsorship changes, and to change information associated with a contact object. This document does not define a mapping for the EPP command. 3.2.1 EPP Command The EPP command provides a transform operation that allows a Hollenbeck Expires July 24, 2002 [Page 16] Internet-Draft EPP Contact mapping January 24, 2002 client to create a contact object. In addition to the standard EPP command elements, the command MUST contain a element that identifies the contact namespace and the location of the contact schema. The element contains the following child elements: - A element that contains the desired server-unique identifier for the contact to be created. - One or two elements that contain postal address information. Two elements are provided so that address information can be provided in both internationalized and localized forms. If an internationalized form is provided, it MUST be listed first and 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 is provided, element content MAY be represented in unrestricted UTF-8. The element contains the following child elements: - A element that contains the name of the individual or role represented by the contact. - An OPTIONAL element that contains the name of the organization with which the contact is affiliated. - A element that contains address information associated with the contact. A element contains the following child elements: - One, two, or three OPTIONAL elements that contain the contact's street address. - A element that contains the contact's city. - An OPTIONAL element that contains the contact's state or province. - An OPTIONAL element that contains the contact's postal code. - A element that contains the contact's country code. - An OPTIONAL element that contains the contact's voice telephone number. - An OPTIONAL element that contains the contact's facsimile telephone number. Hollenbeck Expires July 24, 2002 [Page 17] Internet-Draft EPP Contact mapping January 24, 2002 - A element that contains the contact's email address. - A element that contains authorization information to be associated with the contact object. Example command: C: C: C: C: C: C: sh8013 C: C: John Doe C: Example Inc. C: C: 123 Example Dr. C: Suite 100 C: Dulles C: VA C: 20166-6503 C: US C: C: C: +1.7035555555 C: +1.7035555556 C: jdoe@example.tld C: 2fooBAR C: C: C: ABC-12345 C: C: When a command has been processed successfully, the EPP element MUST contain a child element that identifies the contact namespace and the location of the contact schema. The element contains the following child elements: - A element that contains the server-unique identifier Hollenbeck Expires July 24, 2002 [Page 18] Internet-Draft EPP Contact mapping January 24, 2002 for the created contact. - A element that contains the date and time of contact object creation. Example response: S: S: S: S: S: Command completed successfully S: S: S: S: sh8013 S: 1999-04-03T22:00:00.0Z S: S: S: S: ABC-12345 S: 54321-XYZ S: S: S: An EPP error response MUST be returned if a command can not be processed for any reason. 3.2.2 EPP Command The EPP command provides a transform operation that allows a client to delete a contact object. In addition to the standard EPP command elements, the command MUST contain a element that identifies the contact namespace and the location of the contact schema. The element MUST contain the following child elements: - A element that contains the server-unique identifier of the contact object to be deleted. A contact object SHOULD NOT be deleted if it is associated with other Hollenbeck Expires July 24, 2002 [Page 19] Internet-Draft EPP Contact mapping January 24, 2002 known objects. An associated contact SHOULD NOT be deleted until associations with other known objects have been broken. A server SHOULD notify clients of object relationships when a command is attempted and fails due to existing object relationships. Example command: C: C: C: C: C: C: sh8013 C: C: C: ABC-12345 C: C: When a command has been processed successfully, a server MUST respond with an EPP response with no element. Example response: S: S: S: S: S: Command completed successfully S: S: S: ABC-12345 S: 54321-XYZ S: S: S: An EPP error response MUST be returned if a command can not be processed for any reason. Hollenbeck Expires July 24, 2002 [Page 20] Internet-Draft EPP Contact mapping January 24, 2002 3.2.3 EPP Command Renewal semantics do not apply to contact objects, so there is no mapping defined for the EPP command. 3.2.4 EPP Command The EPP command provides a transform operation that allows a client to manage requests to transfer the sponsorship of a contact object. In addition to the standard EPP command elements, the command MUST contain a element that identifies the contact namespace and the location of the contact schema. The element contains the following child elements: - A element that contains the server-unique identifier of the contact object for which a transfer request is to be created, approved, rejected, or cancelled. - A element that contains authorization information associated with the contact object. Every EPP command MUST contain an "op" attribute that identifies the transfer operation to be performed as defined in [EPP]. Example request command: C: C: C: C: C: C: sh8013 C: 2fooBAR C: C: C: ABC-12345 C: C: When a command has been processed successfully, the EPP element MUST contain a child element that Hollenbeck Expires July 24, 2002 [Page 21] Internet-Draft EPP Contact mapping January 24, 2002 identifies the contact namespace and the location of the contact schema. The element contains the same child elements defined for a transfer query response. Example response: S: S: S: S: S: Command completed successfully S: S: S: S: sh8013 S: pending S: ClientX S: 2000-06-08T22:00:00.0Z S: ClientY S: 2000-06-13T22:00:00.0Z S: S: S: S: ABC-12345 S: 54322-XYZ S: S: S: An EPP error response MUST be returned if a command can not be processed for any reason. 3.2.5 EPP Command The EPP command provides a transform operation that allows a client to modify the attributes of a contact object. In addition to the standard EPP command elements, the command MUST contain a element that identifies the contact namespace and the location of the contact schema. The element contains the following child elements: - A element that contains the server-unique identifier of Hollenbeck Expires July 24, 2002 [Page 22] Internet-Draft EPP Contact mapping January 24, 2002 the contact object to be updated. - An OPTIONAL element that contains attribute values to be added to the object. - An OPTIONAL element that contains attribute values to be removed from the object. - An OPTIONAL element that contains object attribute values to be changed. At least one , , or element MUST be provided. The and elements contain the following child elements: - One or more elements that contain status values to be associated with or removed from the object. When specifying a value to be removed, only the attribute value is significant; element text is not required to match a value for removal. A element contains the following OPTIONAL child elements. At least one child element MUST be present: - One or two elements that contain postal address information. Two elements are provided so that address information can be provided in both internationalized and localized forms. If an internationalized form is provided, it MUST be listed first and 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 is provided, element content MAY be represented in unrestricted UTF-8. The element contains the following child elements: - A element that contains the name of the individual or role represented by the contact. - A element that contains the name of the organization with which the contact is affiliated. - A element that contains address information associated with the contact. A element contains the following child elements: - One, two, or three OPTIONAL elements that contain the contact's street address. - A element that contains the contact's city. Hollenbeck Expires July 24, 2002 [Page 23] Internet-Draft EPP Contact mapping January 24, 2002 - An OPTIONAL element that contains the contact's state or province. - An OPTIONAL element that contains the contact's postal code. - A element that contains the contact's country code. - A element that contains the contact's voice telephone number. - A element that contains the contact's facsimile telephone number. - A element that contains the contact's email address. - A element that contains authorization information associated with the contact object.

The formal syntax presented here is a complete schema representation of the object mapping suitable for automated validation of EPP XML instances. The BEGIN and END tags are not part of the schema; they are used to note the beginning and ending of the schema for URI registration purposes. BEGIN Extensible Provisioning Protocol v1.0 contact provisioning schema.

Internationalization Considerations EPP is represented in XML, which provides native support for encoding information using the Unicode character set and its more compact representations including UTF-8. Compliant XML processors are REQUIRED to understand both UTF-8 and UTF-16. Though XML includes provisions to identify other character set encodings through use of an "encoding" attribute in an declaration, EPP use with character sets other than UTF-8 is NOT RECOMMENDED. All date-time values presented via EPP MUST be expressed in Universal Coordinated Time using the Gregorian calendar. XML Schema allows use of time zone identifiers to indicate offsets from the zero meridian, but this option MUST NOT be used with EPP. The extended date-time form defined in [DATE-TIME] MUST be used to represent date-time values as XML Schema does not support truncated date-time forms. Humans, organizations, and other entities often need to represent social information in both a commonly understood character set and a locally optimized character set. This specification provides features allowing representation of social information in both a subset of UTF-8 for broad readability and unrestricted UTF-8 for local optimization. 6. IANA Considerations This document uses URNs to describe XML namespaces and XML schemas conforming to a registry mechanism described in [IETF-XML]. Two URI assignments are requested. Registration request for the contact namespace: URI: urn:ietf:params:xml:ns:contact-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 contact XML schema: URI: urn:ietf:params:xml:schema:contact-1.0 Registrant Contact: See the "Author's Address" section of this document.

Security Considerations An authorization token is REQUIRED to create a contact object. This token is used in transfer operations as an additional means of determining client authorization to perform the command. Failure to protect authorization tokens can result in unauthorized transfer operations. Both client and server MUST ensure that tokens are stored and exchanged with high-grade encryption mechanisms to provide privacy services. The object mapping described in this document does not provide any other security services or introduce any additional considerations beyond those described by [EPP] and protocol layers used by EPP. 8.

Revisions From Previous Version (Note to RFC editor: please remove this section completely before publication as an RFC.) -03 to -04 (WG last call updates): Fixed typos. Fixed the e164StringType to allow full-length numbers with country codes of less than three characters. Increased the maximum postalLineType length from 64 to 255. Changed type of email and telephone number types to "token" from "normalizedString" since these values should never contain certain acceptable normalizedString characters. Fixed schema to prevent multiple choices in updates, replacing with . Made mandatory for transfer queries. Added a sentence to section 3.2.2 to encourage server implementers to notify clients when a delete command fails due to existing object relationships. Modified the schema to collapse the and elements into a single element that may occur once or twice depending on context. Modified the schema to ensure that required string fields can't be specified as empty strings. Changed some lower-case "must"s, "may"s, etc. to avoid confusion with RFC 2119 directives. Updated the security considerations section to note the need to protect authorization tokens. Separated references into normative and informative subsections. Removed unneeded references to ISO 11180 and US-ASCII. Replaced reference to ISO 8601 with an IMPP I-D that will hopefully be an RFC soon.
