software_ version
Registry Context
software_version is a version identifier for the client software identified by software_id. It should change whenever that software is updated.
Technical Summary
RFC 7591 defines software_version as a string identifying the version of the client software associated with software_id. Its value should change on any update to that software. Values are compared using string equality; no other comparison semantics are defined.
When Used
Used as client metadata in dynamic client registration requests and responses. It can be communicated directly in a registration request, included as a claim in a software statement, or supplied in both locations.
Normative Requirements
Authorization servers
RFC 7591 - Section 2
give the software_version claim in a trusted software statement precedence over the directly supplied client metadata value.
Condition: when software_version is present both in the registration request body and in a software statement trusted by the authorization server
If the same client metadata name is present in both locations and the software statement is trusted by the authorization server, the value of a claim in the software statement MUST take precedence.
Unspecified actor
RFC 7591 - Section 2
change the software_version value.
Condition: on any update to the client software identified by the same software_id
The value of the "software_version" SHOULD change on any update to the client software identified by the same "software_id".
RFC 7591 - Section 2
implement and use the software_version client metadata field.
Condition: unless another applicable specification states otherwise
The implementation and use of all client metadata fields is OPTIONAL, unless stated otherwise.
Validation Guidance
Verify that software_version is represented as a JSON string when present.
Warn when client software is known to have been updated under the same software_id but software_version has not changed.
Compare software_version values using string equality only; do not infer ordering or compatibility from their contents.
When trusted software-statement and direct request values conflict, use the software-statement value.
