For the happiness of search engine crawlers and people which will land
on this thread: it was suggested to me it is possible to directly ask
Tracker about properties mapped on the running ontology, with a query
like:

SELECT ?p ?d ?r
    WHERE { ?p a rdf:Property ; rdfs:domain ?d ; rdfs:range ?r }

Quite obvious, after all...

Anyway, my previous request still remain in place: given the method to
automatically guess datatype for a named property, it would be quite
convenient expose in the TrackerSparqlBuilder's API such a function and
avoid manual implementation for all developers needing this level of
abstraction.
