Re: ldp-ISSUE-11 (Server-managed properties): Do we need to define server-managed properties or do we leave them to applications? [Linked Data Platform core]

I wonder if this does not raise the issue that one should at some point in the spec distinguish what the server says and what the content says. I think HTTP headers is what the server is saying about the content. I think it is clear that the HTTP headers is the space for the server to make statements, such as last modified and who made the edit - as the server can factually know this. The content on the other hand is something said by the content creator. Now the question is then is in true that the following equivalence is true in n3

 { { <> dc:author ?a } = ?doc } <=> { ?doc dc:author ?a } }
