The W3C Data Exchange Working Group [1] has issued first drafts of two
potential standards relating to profiles.

The first is a small ontology for profile resources [2]. This ontology
is based on the case where an application profile is made up of one or
more documents or resources, such as both human-readable instructions
and a SHACL validation document. The ontology links those into a single
graph called a "profile" and states the role of each resource.

The second is a companion to an (in-progress) IETF proposal [3] that
would support requesting web resources that are conformant with a
profile.[4]

If you have an interest in profiles please look at and comment on these
proposals. Instructions for commenting are included in the documents
themselves.

Thank you,
