It wholly depends on what the data in the triple store or file contains. Variable ?predicate
will match the predicate of the triple, and that predicate might be a datatype property or an object property in OWL, or neither of those if you're not querying an OWL ontology. Likewise, ?object
will match an RDF resource or a literal, again depending on what the data says.
