Introduction This document describes a Validate mapping for version 1.0 of the Extensible Provisioning Protocol (EPP) [RFC5730]. This EPP mapping specifies a flexible schema by which EPP clients and servers can reliably validate contact and eligibility data. With the increased number of restrictions on contacts and required data points (license, ids, etc.) to register a domain name, a way to validate the data points prior to issuing a transform command is becoming more important. Carney & Snitker Expires February 4, 2018 [Page 2] Internet-Draft Validate August 2017 1.1. Conventions Used in This Document 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 RFC 2119 [RFC2119]. XML is case sensitive. Unless stated otherwise, XML specifications and examples provided in this document MUST be interpreted in the character case presented in order to develop a conforming implementation. In examples, "C:" represents lines sent by a protocol client and "S:" represents lines returned by a protocol server. Indentation and white space in examples are provided only to illustrate element relationships and are not a REQUIRED feature of this protocol. 2. Object Attributes A EPP validation object has attributes and associated values that can be viewed by the client. This section describes each attribute type in detail. 2.1. Key Value Key Value provides a flexible mechanism to share data between the client and the server. The element defines the data, with two required simple attributes, key and value, and an optional contactType attribute for specificity in the response, more details below. o An example . o An example . 3. EPP Command Mapping A detailed description of the EPP syntax and semantics can be found in [RFC5730]. The command mappings described here are specifically for the Validate Extension. 3.1. EPP Query Commands EPP provides three commands to retrieve object information: to determine if an object is known to the server, to retrieve detailed information associated with an object, and to retrieve object transfer status information. Carney & Snitker Expires February 4, 2018 [Page 3] Internet-Draft Validate August 2017 3.1.1. EPP Command The EPP command is used to validate a list of contact information. The command MUST contain a element that identifies the validate namespace. The element contains the following child elements: o one or more element(s) for each contact that is to be validated that contains the contact type of the contact to be validated. The element MUST contain the following child elements: o one element. o zero or more elements. The element MUST contain the following child elements: o one element. o an OPTIONAL element. o an OPTIONAL element. o an OPTIONAL element. o an OPTIONAL element. o an OPTIONAL element. o an OPTIONAL element. The following is an example command. C: C: 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 Carney & Snitker Expires February 4, 2018 [Page 4] Internet-Draft Validate August 2017 C: US C: C: C: +1.7035555555 C: +1.7035555556 C: jdoe@example.com C: C: 2fooBAR C: C: C: C: C: C: C: C: C: C: C: sh8013 C: C: C: C: C: sh8014 C: C: John Doe C: Example Inc.

The element MUST contain a element for each element contained in the command. The element MUST contain the following child elements: o one element. o one element. o zero or more elements.

EPP Command Info semantics do not apply to validate objects, so there is no mapping defined for the EPP command. 3.1.3. EPP Command Transfer semantics do not apply to validate objects, so there is no mapping defined for the EPP command. Carney & Snitker Expires February 4, 2018 [Page 7] Internet-Draft Validate August 2017 3.2. EPP Transform Commands EPP provides five commands to transform objects: to create an instance of an object with a server, to remove an instance of an object from a server, to extend the validity period of an object, to manage changes in client sponsorship of an object, and to change information. 3.2.1. EPP Command Create semantics do not apply to validate objects, so there is no mapping defined for the EPP command. 3.2.2. EPP Command Delete semantics do not apply to validate objects, so there is no mapping defined for the EPP command. 3.2.3. EPP Command Renew semantics do not apply to validate objects, so there is no mapping defined for the EPP command. 3.2.4. EPP Command Transfer semantics do not apply to validate objects, so there is no mapping defined for the EPP command. 3.2.5. EPP Command Update semantics do not apply to validate objects, so there is no mapping defined for the EPP command. 4. Formal Syntax One schema is presented here that is the EPP Validate schema. 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. 4.1.

Security Considerations The mapping extensions described in this document do not provide any security services beyond those described by EPP [RFC5730] and protocol layers used by EPP. The security considerations described in these other specifications apply to this specification as well. 6. IANA Considerations 6.1. XML Namespace This document uses URNs to describe XML namespaces and XML schemas conforming to a registry mechanism described in [RFC3688]. The following URI assignment is requested of IANA: URI: ietf:params:xml:ns:validate-1.0 Registrant Contact: See the "Author's Address" section of this document. XML: See the "Formal Syntax" section of this document. Carney & Snitker Expires February 4, 2018 [Page 11] Internet-Draft Validate August 2017 7. Implemntation Status Note to RFC Editor: Please remove this section and the reference to [RFC6982] 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 [RFC6982]. The description of implementations in this section is 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 [RFC6982], "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. To Be Filled In Add implementation details once available. 8. Acknowledgements The authors wish to thank the following persons for their feedback and suggestions: o Kevin Allendorf of GoDaddy Inc. o Jody Kolker of GoDaddy Inc. o James Gould of Verisign Inc 9. Change History 9.1. Change from 00 to 01 Corrected some formatting issues Carney & Snitker Expires February 4, 2018 [Page 12] Internet-Draft Validate August 2017 9.2. Change from 00 to 01 After review and broad feedback, extensive changes have been made transforming the original document from a standalone extension command to using the command and response framework. Stubbed in an Implementation section for later documentation. 9.3. Change from carney-regext 01 to ietf-regext 00 Updated miscellaneous verbiage to reflect the change from an extension and changed to ietf naming as REGEXT WG will assume this work. 10.
