Hi Lars, everyone,
In the past two weeks there's been a discussion about Linked Data Profiles on the W3C public linked open data list:
https://lists.w3.org/Archives/Public/public-lod/2015May/thread.html ("Profiles in Linked Data")
It looks relevant, and it's a very long thread!
Lars, you have started it, would it be possible for you to report on it in one of the coming bi-weekly calls of the RDF AP group?
At the call today, we were quite curious to hear whether you think there's something we should do!
