Greetings, I have a set of N-Quad statements that relate to different graphs. How do I go about exporting all those statements into a single JSON-LD object?
For instance, I would expect that something like: <http://one.example/subject3> <http://one.example/predicate3> < http://one.example/object3> <http://example.org/graph3> . _:subject1 <http://an.example/predicate1> "object1" < http://example.org/graph1> . _:subject2 <http://an.example/predicate2> "object2" < http://example.org/graph2> . would end up as the following JSON-LD (disclaimer: I'm not 100% sure this is correct, JSON-LD wise): [ { "@context": { "predicate3": "http://one.example/predicate3"; }, "@id": "http://example.org/graph3";, "@graph": [ { "@id": "http://one.example/subject3";, "predicate3": "http://one.example/object3"; } ] }, { "@context": { "predicate1": "http://an.example/predicate1"; }, "@id": "http://example.org/graph1";, "@graph": [ { "@id": "_:b0", "predicate1": "object1" } ] }, { "@context": { "predicate2": "http://an.example/predicate2"; }, "@id": "http://example.org/graph2";, "@graph": [ { "@id": "_:b0", "predicate2": "object2" } ] } ] So far, the approach I took was to load the n-quads using: RDFDataMgr.read(dataset, in, RDFLanguages.NQUADS); and then iterate through the graph names, to get each model with: Model model = dataset.getNamedModel(name); Something like model.write(out, RDFLanguages.strLangJSONLD); works well to convert the data to JSON-LD, however it does not add any graph info (@graph). While I could probably stitch those parts together, I was hoping for a cleaner way to do this. In particular, I tried to create a new model by uniting 2 models at a time but it did not quite work (although I do see @graph added)... Can anyone shed some light on the best approach for this? Cheers, Hubert PS: my apologies if it's already been discussed before but I did not find anything on this particular topic in the list archive.
