draft-jurkovikj-http-semantic-validator
Semantic Validators for HTTP
This document defines the Semantic-ETag HTTP response header field
and two associated conditional request header fields. Unlike the
standard ETag field, which identifies a selected representation,
Semantic-ETag identifies a server-defined semantic equivalence class
for the underlying resource state. This enables origin servers to
support representation-independent validation and optimistic
concurrency control across different representations, such as HTML,
JSON, and Markdown views of the same logical resource.
This document does not update or replace the semantics of the ETag
header field defined in RFC 9110.
