Fedora 13 as semantic desktop?

  Nautilus + Tracker tags integration
  After viewing this video I tried enabling Fedora (Gnome) to have these semantic desktop features.
  yum install nautilus-python tracker-search-tool tracker
  After restarting nautilus I enabled nautilus sidebar but didn't see this feature there. Is this a bug or am I doing something wrong?
  You can read about this feature more in this article: A Metadata Enabled GNOME
  I also posted a bugzilla bug report regarding this issue and there is also a Fedora forum post also (not posted by me).
After reading blog post from Debarshi some things got much more clear, so what we need is newer version of tracker in Fedora, this could be a cool new feature. Fedora 13 should have semanatic desktop features if it is possible, all Fedora users would surely appreciate that.
