Hey list, I want to improve provenance of RDF data in my app, and I'm mostly looking at named graphs since reification seems not be used that much.
One point of view is logical divisions: - read-only core ontologies - user ontologies - user instance data I could make a named graph for each of them. The other is that I'd like to have metadata about every added/updated triple so the app could say "User X updated resource Y with value of Z on date W". In this case basically every triple should have its own unique URI - i.e. be a named graph with a single statement? It seems that I could implement either the first case or the second with named graphs, but not both, which I would prefer. How would you go about it - has anyone worked on use cases like this? Should I still consider reification - and maybe use it together with named graphs? Thanks, Martynas semantic-web.dk
