Hm, maybe this is where we are thinking differently: I’m thinking of profile-based negotiation as selecting a version of a dataset based on the profile it is designed to support. Here you mention selecting only the metadata that comes with the dataset. Suppose we have two profiles that use two different controlled value lists for the same variable. In my view, selecting profile 1 means that I will get different data than profile 2. The metadata will be different, too, but the fact that the actual values returned differ seems important.

That sample has different metadata for different audiences (legacy XML format, current SOSA RDF etc.) but we certainly want the same URI for the sample. Currently we're using query string args to separate out the profiles but would like to support HTTP profile negotiation for smarter machine clients.
