Thanks Andy. This is exactly what I was looking for.
When connecting to a SPARQL endpoint, I'm doing:
DatasetAccessor accessor = DatasetAccessorFactory.createHTTP("http://....";);
And it seems, that I could do the same for a Dataset:
String directory = "";
Dataset dataset = TDBFactory.createDataset(directory);
DatasetAccessor accessor = DatasetAccessorFactory.create(dataset);
Regardless if it's a SPARQL Endpoint or a local dataset, it seems that I
can use methods like accessor.add(nameURI, m);
Before, per my previous email, when connecting to a Dataset, I was being
explicit with the transactions: begin, commit, end etc.
If I connect to a Dataset through a DatasetAccessor, should I also begin,
commit, etc the dataset?
Thanks!
