Extensible Provisioning Protocol (EPP) and Registration Data Access Protocol (RDAP) Status Mapping
draft-ietf-regext-epp-rdap-status-mapping-04

Abstract

This document describes the mapping of the Extensible Provisioning Protocol (EPP) statuses with the statuses registered for use in the Registration Data Access Protocol (RDAP). This document identifies gaps in the mapping, and registers RDAP statuses to fill the gaps to ensure that all of the EPP RFC statuses are supported in RDAP.

Table of Contents

1. Introduction

This document maps the statuses defined in the Extensible Provisioning Protocol (EPP) RFCs to the list of statuses registered for use in the Registration Data Access Protocol (RDAP), in the RDAP JSON Values Registry [rdap-json-values].

The RDAP JSON Values Registry is described in section 10.2 of [RFC7483] and is available in the RDAP JSON Values Registry [rdap-json-values].

The EPP statuses used as the source of the mapping include section 2.3 of the Extensible Provisioning Protocol (EPP) Domain Name Mapping [RFC5731], section 2.3 of the Extensible Provisioning Protocol (EPP) Host Mapping [RFC5732], section 2.2 of the Extensible Provisioning Protocol (EPP) Contact Mapping [RFC5733], and section 3.1 of Domain Registry Grace Period Mapping for the Extensible Provisioning Protocol (EPP) [RFC3915].

Each EPP status MUST map to a single RDAP status to ensure that data in the Domain Name Registries (DNRs) that use EPP can be accurately presented in RDAP.

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].

2. EPP to RDAP Status Mapping

Below is an alphabetically sorted list of EPP statuses from the EPP RFCs ([RFC5731], [RFC5732], [RFC5733], and [RFC3915]) mapped to the RDAP statuses registered in the RDAP JSON Values Registry [rdap-json-values], with the format <EPP Status> '=' <RDAP Status>, where a blank <RDAP Status> indicates a gap in the mapping.

The RDAP JSON Values Registry [rdap-json-values] does have a set of prohibited statuses including "renew prohibited", "update prohibited", "transfer prohibited", and "delete prohibited", but these statuses do not directly map to the EPP prohibited statuses. EPP provides status codes that allow distinguishing the case that an action is prohibited because of server policy from the case that an action is prohibited because of a client request. The ability to make this distinction needs to be preserved in RDAP.

Each of the EPP status values that don't map directly to an RDAP status value is described below. Each EPP status value includes a proposed new RDAP status value and a description of the value. The RDAP status value is derived from the EPP status value by converting the EPP camel case representation to lower case with a space character inserted between word boundaries.

addPeriod = add period;
This grace period is provided after the initial registration of the object. If the object is deleted by the client during this period, the server provides a credit to the client for the cost of the registration.
autoRenewPeriod = auto renew period;
This grace period is provided after an object registration period expires and is extended (renewed) automatically by the server. If the object is deleted by the client during this period, the server provides a credit to the client for the cost of the auto renewal.
clientDeleteProhibited = client delete prohibited;
The client requested that requests to delete the object MUST be rejected.
clientHold = client hold;
The client requested that the DNS delegation information MUST NOT be published for the object.
clientRenewProhibited = client renew prohibited;
The client requested that requests to renew the object MUST be rejected.
clientTransferProhibited = client transfer prohibited;
The client requested that requests to transfer the object MUST be rejected.
clientUpdateProhibited = client update prohibited;
The client requested that requests to update the object (other than to remove this status) MUST be rejected.
pendingRestore = pending restore;
An object is in the process of being restored after being in the redemption period state.
redemptionPeriod = redemption period;
A delete has been received, but the object has not yet been purged because an opportunity exists to restore the object and abort the deletion process.
renewPeriod = renew period;
This grace period is provided after an object registration period is explicitly extended (renewed) by the client. If the object is deleted by the client during this period, the server provides a credit to the client for the cost of the renewal.
serverDeleteProhibited = server delete prohibited;
The server set the status so that requests to delete the object MUST be rejected.
serverRenewProhibited = server renew prohibited;
The server set the status so that requests to renew the object MUST be rejected.
serverTransferProhibited = server transfer prohibited;
The server set the status so that requests to transfer the object MUST be rejected.
serverUpdateProhibited = server update prohibited;
The server set the status so that requests to update the object (other than to remove this status) MUST be rejected.
serverHold = server hold;
The server set the status so that DNS delegation information MUST NOT be published for the object.
transferPeriod = transfer period;
This grace period is provided after the successful transfer of object registration sponsorship from one client to another client. If the object is deleted by the client during this period, the server provides a credit to the client for the cost of the transfer.

The resulting mapping after registering the new RDAP statuses is:

3. IANA Considerations

3.1. JSON Values Registry

The following values should be registered by the IANA in the RDAP JSON Values Registry described in [RFC7483]:

4. Security Considerations

The status values described in this document can be subject to server-side information disclosure policies that restrict display of the values to authorized clients. Implementers may wish to review [RFC7481] for a description of the RDAP security services that can be used to implement information disclosure policies.
