Reasoning with Stardog-groovy

[Daniel Stieglitz]

What's the best way to enable/use Stardog's reasoning capabilities through stardog-groovy? According to the documentation I need to enable a reasoning level, and then I assume I can add axions and queries should return inferred results. Is this correct?

Hi Dan,

At the moment, the best way is probably to initialize the
ext.groovy.Stardog with the ext.spring.DataSource. You can configure
the DataSource with a ReasoningType.

I'll add the same option directly to the ext.groovy.Stardog constructor.

Hi Al

Thanks for the reply, what I ended up doing was looking up what you did in the Stardog class and re-writing that logic with a raw connection, reasoning enabled. Works like a charm:

   def doReasoningQuery(queryString) {

        Connection c = ConnectionConfiguration

                .to(db_name)

                .url(stardog_url)

                .credentials(db_user, db_pass)  // credentials to use while connecting

                .reasoning(ReasoningType.QL)    // now lets specify that we want a db w/ QL reasoning

                .connect();

        def q = c.query(queryString)

        TupleQueryResult r = q.executeSelect();

        while (r.hasNext()) {

            println r.next();

        }

        r.close();

    }
