All this is true and better than before, but it is, in reality, not for _profile_ but for _vocabulary_ authors. These two are different: profile authors do not necessarily author profiles! This should be made crystal clear.

I understand that, and that is indeed good to have.

Sorry if give only very general guidelines here, apart from not being not really well, it is is also a bit late here. I just wanted to have this said...

So... I think there three different 'audience' to the page (and it is fine to have all this on one)

- Authors of vocabularies. Issues like stability of semantics, long term URI-s, etc.
- Authors of profiles in general. Issues like, for example, cache control in the HTTP headers, stuff like
- Authors of default profiles (like me:-). Specific URI-s, and expected refresh range. And it should be clear that we do not have yet a clear policy on how vocabulary prefixes or terms would get on those!
- Authors of RDFa files 

The last entry is your last entry on the wiki page, but I have the impression that it would make it clearer if the different entries were restructured along the first three items.

Just a thought. Again, I do not have time right now to get this things into a more specific form, and may not be realizable. So it is just a food for thoughts...


Good night!

Ivan
