Here is my use case: We have a lot of documents each of which consists of several hundred statements. Every document has some metadata such as when it was last revised. This information can easily be indicated when such a document is stored in a single file, using rdf:about="". The other solution of course would be to reify all statements, which is definitely not practical (which is not to say that reification isn't useful for making assertions about individual statements). The important point is that I can no longer make use of this metadata after loading the data into an RDF database (e.g. retrieve a set of statements or search only statements that are available under a license that allows non-commercial use), unless the database supports some kind of context. I would be quite surprised if I were the only person on this planet with this problem... > context can be done in a way that is RDF-friendly and useful without > needing quads though - check the good Mr. Beckett's approach in > Redland: For all I can tell he *is*, in principal, using quads, isn't he? graph.add(triple, identifier)
