Storing Metadata [was: Dataset Syntax - checking for consensus]

Hi all,

I was watching the thread on on Dataset Syntax[1] and wanted to share
how we store metadata in Callimachus. When a graph is imported into
Callimachus it is given a "local" URI, a URI that resolves to the
Callimachus server. The metadata about who uploaded and when it was
uploaded is stored in another metadata graph (we call it an activity
graph now). I wrote up some examples of these graphs in a blog post
titled Provenance and Traceability in RDF with Callimachus[2]. Check out
the last example for a metadata graph that describes importing another
graph.

Hope this helps,
James
