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 [1] http://lists.w3.org/Archives/Public/public-rdf-wg/2012Sep/0249.html [2] http://jamesrdf.blogspot.ca/2012/10/provenance-and-traceability-in.htmlReceived on Thursday, 4 October 2012 15:18:49 UTC
