well the new language would be for new features as well as replacing old ones. Like you said we want more power to be exposed however that will take time. I also want to widgetise everything so we can reuse them in other tools like a tracker powered file manager > > Just a quick question, I suppose I could look this up anyway :) but > doesn't the FTS module use the old ontologies?

That would make tracker look much slower than it is?

We can store as linked list in rdf - should not be hard jamie _______________________________________________ tracker-list mailing list [email protected] http://mail.gnome.org/mailman/listinfo/tracker-list
