Hello, I want to be able to load a set of ontologies into dataset in order to be able to have named graph support in my SPARQL queries against said dataset. Specifically, I would like to be able to use FROM, FROM NAMED, and GRAPH clauses in my SPARQL.
>From my investigation, it appears that full named graph support is only available with TDB datasets, but not available when creating a dataset using DatasetFactory. Specifically, against a DatasetFactory created dataset, using FROM in the query appears to have no affect at all, and even using FROM NAMED has no affect over simply having GRAPH in the query. Am I correct, or is there something I'm missing? Perhaps there is a specific implementation of DatasetGraph that I should be creating? I have sample code, but thought I'd simply ask the question in hopes that there's a simple answer, either way. Please let me know if the sample code will be useful. -- Cheers, Willie
