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).
 
UPDATE:
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.
