It may be that there are various notions of "profile" in play here. I'll
check in with Ed! If there are interesting quantities of data out there
expressed in DCAT-based patterns (potentially captured via shex/shacl
shapes) and if they're written in a form we extract (json-ld etc) then
there's certainly potential.  Can you give examples of any pages (rather
than the underlying specs) with the kind of dataset-describing profile you
have in mind? Re fora, I'm happy having a mail thread here until the WG
chairs nudge us to move along elsewhere :)
