We recently added the tracker:id() function for this purpose. It's not part of any RDF or SPARQL spec and completely custom / specialized for Tracker use. So if you do use this, your queries aren't compatible with any other SPARQL or RDF product. It's so new that we have not documented it yet, it's also not available in any release yet (afaik).
