Jeni's Musings

I'm a bit hesitant about serializing Named Graphs in everyday Web documents. I heavily use Named Graphs to track provenance, by loading each document into its own Named Graph internally. If I would allow documents to contain several Named Graphs, then essentially someone could fool my store by claiming that this is the graph representing some other document. Does this mean I need to move to Quintuples for my internal data model?

That's why I prefer solutions that remain within the standard RDF data model, and I advocate the solution of creating classes representing the time-scoped relationship in your vocabulary.

Jiri Prochazka and I have written up a little draft RDFS extension that might help with mapping such relationship classes into the pure triple form: Property Reification Vocabulary.

But anyway, this is an important and interesting topic and it's good to see this well thought out proposal.
