Having read the discussion last month about Named Graphs, I find myself still a bit confused.
I'm developing an OWL app which uses SDB as the repository. In the repository are many Models which are named graphs representing resources, and some Models which are ontologies (referenced by the resources, via the SDB DocumentManager). I tried connecting to this pre-existing store from TBS (Maestro Edition), and had a couple of odd results. First, if I create the .sdb file using the wizard under New / RDF/OWL Jena SDB Database Connection, I can access the default graph (if I don't fill in the "Named Graph URI" field, or any specific graph if I put its URI in the field, but there doesn't appear to be a way to access the database as a whole. For example, I'd like to be able to query for all graphs which contain a triple matching a pattern. The template for doing this (in the SPARQL by example presentation) doesn't work for me. Second, re-opening an existing .sdb file never seems to work. An exception is invariably thrown: "Could not load \TopBraid\SDBRepository.sdb or one of its imports. The most recent URI was http://localhost/dataStore No matching StoreCache entry found" Once I get this error I must restart TBS before I can look at the database again. Any guidance on what this means? Are there stricter requirements for the contents of the database than I am aware of, for example? (Things I must add to be TBS-compatible, for example. I note a reference in the .sdb file to a "config" model that I don't create...)
