:Hi *,
I am doing my first babysteps with jena/fuseki. What I would like to get
is a fuseki server running that connects to a mysql database and uses an
owl reasoner. After lots of fiddling and googling I got it to run for in
memory and tdb, but sdb still gives me problems. The triples are
inserted into mysql, but on the select I only get dog1 - so the
reasoning doesn't seem to work.
Below my INSERT, SELECT, expectation, results and my configuration.
Any hints what I did wrong in my config?
I'm not completely sure but

I think that needs to be ja:RDFDataset (see the TDB case) because the
assembler is possibly finding sdb:DatasetStore, making that the dataset
and so ignoring the ja:defaultGraph and hence the inference engine.
