I have some Java code in which I have added triples to the database as part of
a named model. Using SQL, I have confirmed that column quads.g contains a
reference to the name that I have provided. I can also query that model in Java
and retrieve the triples. For example, I have the following query in a file.
select ?s
where { ?s rdf:type :Individual }
It is not clear how to do the same query using sdbquery. By default, when I run
this query it returns no results. I assume that is because the query is only
against the default graph. How do I instruct the query to include the named
model? I tried using the FROM NAMED construct in the query itself, but I get
the following exception:
com.hp.hpl.jena.sdb.SDBException: Queries with dataset descriptions (FROM/FROM
NAMED) not supported
Ideally, I would like to specify the model being used on the command line or be
able to identify the named model in the configuration file and refer to it. Is
there a way to use named models with sdbquery???
