A conversational tool for handling SPARQL queries.
Examples:
List values = createSelectQueryContext(rdfService, queryString)
.bindVariableToUri("uri", uri)
.execute()
.toStringFields("partner")
.flatten();
QueryHolder qh = queryHolder(queryString)
.bindToUri("uri", uri));
List map = createSelectQueryContext(model, qh)
.execute()
.toStringFields();
The query context can come from either an RDFService or a Model.
The execute() method does not actually execute the query: it merely sets it
up syntactically.
If you don't supply any field names to toStringFields(), you get all of
them.
Any string value that returns a blank or empty string is omitted from the
results. Any row that returns no values is omitted from the results.
