The Tracker developers have shown to be particularly ignorant of any
RDF/SPARQL related subjects in the past. See for example the messages I've
sent to the "Proposing Tracker for inclusion into GNOME 2.18" thread [1] on
desktop-devel-list one and a half years ago: [2--7]. The messages linked to
are all by me, but you may also find the comments by Ross Burton useful. The
thread is quite large so don't even try to read all of it... :)
