Introduction This document describes the technical details of the interfaces provided by the Internet Corporation for Assigned Names and Numbers (ICANN) to Registrars and Data Escrow Agents to fulfill the data escrow requirements of the Registrar Accreditation Agreement [ICANN-RAA-2013] and the Registrar Data Escrow Specifications [ICANN-RDE-SPEC]. Extensible Markup Language (XML) 1.0 as described in [W3C.REC-xml-20081126] is used in this specification. Lozano & Alvarez Expires September 21, 2022 [Page 2] Internet-Draft ICANN Registrar Interfaces Mar 2022 The provisioning of credentials and authentication methods used in the interfaces is outside of this document's scope. 1.1. Terminology The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in BCP 14 [RFC2119] [RFC8174] when, and only when, they appear in all capitals, as shown here. 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. 1.2. Date and Time Numerous fields indicate "date and time", such as the creation and receipt dates for data escrow deposits. These fields SHALL contain timestamps indicating the date and time in UTC as specified in [RFC3339], with no offset from the zero meridian. 1.3. Common elements used in this specification Common elements used in this specification are explained in this section. o : The base URL used in the reporting interfaces examples must be replaced with the URL indicated by ICANN. o This document uses the term of "Differential" deposit as defined in the Registry Data Escrow Specification (see, [RFC8909]), while the Registrar Data Escrow Specifications [ICANN-RDE-SPEC] refers to the same concept as "Incremental" deposit. o A-label and NR-LDH, as defined in [RFC5890]. 2. Interfaces for Registrar Data Escrow Notifications This section describes the interfaces provided by ICANN to the Registrars and Data Escrow Agents to fulfill their reporting requirements related to Registrar Data Escrow Specifications [ICANN-RDE-SPEC]. Lozano & Alvarez Expires September 21, 2022 [Page 3] Internet-Draft ICANN Registrar Interfaces Mar 2022 2.1. Registrar Reporting To notify that a data escrow deposit has been submitted to a Data Escrow Agent, the ICANN-accredited Registrar sends a object (see, [I-D.lozano-icann-registry-interfaces]) to ICANN. The following considerations apply for a object corresponding to a data escrow deposit for a Registrar repository: o The element in the object (see, [RFC9022]) MUST be present and have a value corresponding to the IANA Registrar ID assigned by ICANN. o A element MUST be included with the corresponding "rcdn" attribute in the object to indicate the total domains in the Registrar repository for each Registry Class Domain Name (e.g., example) with at least one domain name allocation at a specific point in time (watermark), regardless of the type of deposit: full or differential. * If the "https://www.icann.org/en/system/files/files/rde-specs- 09nov07-en.pdf" specification is being used as the , then the "uri" attribute in the elements for domain names MUST have a value of "urn:ietf:params:xml:ns:rdeDomain-1.0". o To indicate that a Registrar repository has no domain names, one element MUST be included with the "uri" attribute value of "urn:ietf:params:xml:ns:rdeDomain-1.0", no "rcdn" attribute, and a value of 0 (zero). The object for each deposit successfully sent to the Data Escrow Agent is sent using the PUT HTTP verb in the interface provided by ICANN at: /report/registrar-escrow-report// Where: * MUST be substituted with the IANA Registrar ID assigned by ICANN for which the report is being provided. * MUST be substituted with the identifier assigned to the report, which MUST be the same as the "id" attribute from the . Lozano & Alvarez Expires September 21, 2022 [Page 4] Internet-Draft ICANN Registrar Interfaces Mar 2022 Note: The interface supports overwriting the information of a particular report to support asynchronous interfaces between Registrars and Data Escrow Agents.

Data Escrow Agent Reporting The Registrar Data Escrow Specification requires that Registrar Data Escrow Agents deliver to ICANN a notification every time a successfully processed deposit is received from the Registrar regardless of the final status of the verification process, in addition to a failure notification if a scheduled deposit is not received from a Registrar. In order to satisfy this requirement, the Data Escrow Agent sends to ICANN a object as defined in Section 2 of [I-D.lozano-icann-registry-interfaces], to ICANN using the POST HTTP verb in the interface provided by ICANN at: /report/registrar-escrow-agent-notification/ Where: * MUST be substituted with the IANA Registrar ID assigned by ICANN for which the notification is being provided. A with DRFN (Deposit Receipt Failure Notice) status is used to notify that a data escrow deposit has not been processed for verification for a past date where a deposit was scheduled to be received from the Registrar. Lozano & Alvarez Expires September 21, 2022 [Page 6] Internet-Draft ICANN Registrar Interfaces Mar 2022 In addition to the considerations listed in Section 2.1 for the object of the notification, if the data escrow deposit does not include an , a unique value MUST be generated by the Data Escrow Agent to reference the deposit and it MUST be provided in the element. In the case of a with DVFN (Deposit Verification Failure Notice) status, the element MUST be present and include a object for each deposit verification error condition and specify in the corresponding "domainCount" attribute the number of domain names with such error conditions. Note: an error condition may be present several times in the same domain escrow record (e.g., the administrative, technical and billing contact contains invalid email syntax). In this case only one domain name is affected by the error condition, therefore the "domainCount" attribute value must be increased by one in the corresponding object. The following table defines the result codes and messages that a Data Escrow Agent could use to report verification issues found in a Registrar data escrow deposit. When using result codes 2102, 2103, 2104, 2105, 2106, 2107, 2108, 2109, or 2110, the "domainCount" attribute MUST be present.

Internationalization Considerations The interfaces described in this document use 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 declaration, use of UTF-8 is RECOMMENDED. 6. IANA Considerations No actions are required from IANA. 7. Implementation Status Note to RFC Editor: Please remove this section and the reference to RFC 7942 [RFC7942] before publication. This section records the status of known implementations of the protocol defined by this specification at the time of posting of this Internet-Draft, and is based on a proposal described in RFC 7942 [RFC7942]. The description of implementations in this section is Lozano & Alvarez Expires September 21, 2022 [Page 22] Internet-Draft ICANN Registrar Interfaces Mar 2022 intended to assist the IETF in its decision processes in progressing drafts to RFCs. Please note that the listing of any individual implementation here does not imply endorsement by the IETF. Furthermore, no effort has been spent to verify the information presented here that was supplied by IETF contributors. This is not intended as, and must not be construed to be, a catalog of available implementations or their features. Readers are advised to note that other implementations may exist. According to RFC 7942 [RFC7942], "this will allow reviewers and working groups to assign due consideration to documents that have the benefit of running code, which may serve as evidence of valuable experimentation and feedback that have made the implemented protocols more mature. It is up to the individual working groups to use this information as they see fit". 7.1.
