Hello Lucian

as far as I know, there is no such export tool, but there is
tracker-import which can import ttl files. Writing a client using
tracker-sparql that writes to a ttl file shouldn't be too complex.
However, you can't run unrestricted predicate queries using traker (so
no SELECT ?s ?p ?o WHERE {?s ?p ?o}), not sure if selecting first all
the rdfs:Resource, and then SELECT ?p ?o WHERE { <uri> ?p ?o } would be
enough.
