Internet-Draft Registry Fee Extension for EPP November 2013 1. Introduction Historically, domain name registries have applied a simple fee structure for billable transactions, namely a basic unit price applied to domain <create>, <renew>, <transfer> and RGP restore commands. Given the relatively small number of EPP servers to which EPP clients have been required to connect, it has generally been the case that client operators have been able to obtain details of these fees out-of-band by contacting the server operators. Given the imminent expansion of the DNS namespace, and the proliferation of novel business models, it is now desirable to provide a method for EPP clients to query EPP servers for the fees and credits associated with certain commands and specific objects. This document describes an extension mapping for version 1.0 of the Extensible Provisioning Protocol (EPP) [RFC5730]. This EPP mapping provides a mechanism by which EPP clients may query the fees and credits associated with various billable transactions. 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. "fee" is used as an abbreviation for "urn:ietf:params:xml:ns:fee-0.3". The XML namespace prefix "fee" is used, but implementations MUST NOT depend on it and instead employ a proper namespace-aware XML parser and serializer to interpret and output the XML documents. The XML namespace prefix above contains a version number, specifically "0.3". This version number will increment with successive versions of this document, and will reach 1.0 if and when this document is published as an RFC. This permits clients to distinguish which version of the extension a server has implemented. 2. EPP Command Mapping A detailed description of the EPP syntax and semantics can be found in [RFC5730].

Internet-Draft Registry Fee Extension for EPP November 2013 2.1. EPP Query Commands This extension does not add any elements to the EPP <check> or <poll> commands or responses. 2.1.1. EPP <info> Command This extension defines additional elements for the EPP <info> command. The command frame MAY contain an <extension> element which contains a <fee:info> element with the following child elements: o A <fee:currency> element that contains the currency the fee is charged in. This must be a three-character currency code from [ISO4217] (Note: ISO 4217 provides the special "XXX" code which may be used if the server uses a non-currency based system for assessing fees, such as a system of credits). o A <fee:action> element identifying the command. The element values supported by the server is a matter of repository policy, but MUST include as a minimum the following values: * "create" indicating a <domain:create> command; * "renew" indicating a <domain:renew> command; * "transfer" indicating a <domain:transfer> command; If the server supports the Registry Grace Period Mapping [RFC3915], then the server MUST also support the "restore" value. The <fee:action> element MAY have an OPTIONAL "phase" attribute specifying a launch phase as described in [draft-tan-epp-launchphase]. The <fee:action> element may also contain an OPTIONAL "subphase" attribute identifying the custom or sub-phase as described in [draft-tan-epp-launchphase]. o A <fee:period> element that contains the number of units to be added to the registration period of the domain object.

The <fee:infData> MUST contain the following child elements: o A <fee:currency> element that contains same currency code that appeared in the original <fee:check> element. o A <fee:action> element that contains same action that appeared in the original <fee:check> element. This element MAY have the OPTIONAL "phase" and "subphase" elements, which MUST match the same attributes in the original <fee:check> element. o A <fee:period> element that contains same unit that appeared in the original <fee:check> element. o A <fee:fee> element that contains the fee associated with the specified transaction. If the domain name requested in the command is invalid, sponsored by another client, or otherwise ineligible for registration, the server MAY choose to omit the <fee:infData> element and return an error instead.

The security considerations described in these other specifications apply to this specification as well. 4. IANA Considerations This document uses URNs to describe XML namespaces and XML schemas conforming to a registry mechanism described in [RFC3688]. Two URI assignments were requested and have been registered by the IANA. Registration request for the digital signature namespace: URI: urn:ietf:params:xml:ns:fee-0.3 Registrant Contact: See the "Author's Address" section of this document. XML: None. Namespace URIs do not represent an XML specification.
