| Internet-Draft | RDAP Status Set Extension | July 2026 |
| Gould, et al. | Expires 21 January 2027 | [Page] |
This document describes an Registration Data Access Protocol (RDAP) extension for including status sets assigned to RDAP object classes, such as the Domain Object Class and the Nameserver Object Class in [RFC9083]. There can be many overlapping reasons for each of the "status" member values, such as implementing a lock service, complying with a court order, or addressing domain abuse. A status set defines an object representing the reason for setting a "status" value, so clients and servers can effectively manage the overlapping reasons of individual "status" values using the status sets. This RDAP extension supports returning the assigned client and server status sets with additional data members, such as the mapped "status" values and when the status set was assigned.¶

This document describes an Registration Data Access Protocol (RDAP) extension for including status sets assigned to RDAP object classes, such as the Domain Object Class and the Nameserver Object Class in [RFC9083]. There can be many overlapping reasons for each of the "status" member values, such as implementing a lock service, complying with a court order, or addressing domain abuse. A status set defines an object representing the reason for setting a "status" value, can effectively manage the overlapping reasons of individual "status" values using the status sets. This RDAP extension supports returning the assigned client and server status sets with additional data members, such as the "type", the mapped "status" values, whether the status set is inherited either from the parent object (domain) or to child objects (nameservers), and whether the status set is directly assigned.¶
This document is complementary to the Extensible Provisioning Protocol (EPP) Status Set Extension [I-D.gould-regext-epp-status-set], but registry operators do not need to implement that extension in their EPP server in order to implement this RDAP extension.¶
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.¶
The example RDAP responses don't include all of the RDAP response members, but are only representative of the members that are relavant to this extension.¶
Servers implementing this extension MUST include the string "statusSet" in the "rdapConformance" ([RFC9083]) array of all relevant RDAP responses. The registration of the "statusSet" extension identifier is described in Section 6.¶
The status set information is conveyed via a new top-level object member named "statusSet_data" within the object class that the status sets are assigned to. A status set is an object that defines the reason for the "status" member values for an RDAP object class, such as the Domain Object Class and the Nameserver Object Class in [RFC9083]. The status set can also be used as a marker status set when there are no mapped "status" member values that can drive additional business logic and publishing use cases. An object can have many assigned status sets, and the status sets can include an overlapping set of "status" member values. The "status" member value will be assigned to the object if there is at least one set set assigned to the object with the mapped "status" member value. The "status" member value will be unassigned from the object when all status sets are unassigned with the mapped "status" member value. For example, both the "Registrar Lock" status set and the "Auth Token Lock" status set are mapped to the "client update prohibited" "status" member value, where if either of the status sets are assigned to the object, the "client update prohibited" "status" member value will be assigned. The "client update prohibited" "status" member value will be unassigned if both "Registrar Lock" status set and "Auth Token Lock" status sets are unassigned. The "statusSet_data" member includes a list of status set objects containing the following members:¶

This extension supports the Point Versioning defined in [I-D.ietf-regext-rdap-versioning] with a Point Extension Version Identifier of "statusSet-0.1". When there are interface changes to the extension, the Point Extension Version Identifier will be incremented, which may not match the draft version number. When the draft becomes a working group document and passes Working Group Last Call (WGLC), the Point Extension Version Identifier will be changed to "statusSet-1.0".¶
IANA is requested to register the following value in the RDAP Extensions Registry:¶
Status set data may include legal and policy implications. Servers MUST ensure that disclosure of this information complies with applicable data protection laws and policies.¶
