</pimo:Tag>

I'm not sure if the above code fits with the specifications but it is
more or less what I have in mind. Also, I'm very interested to know if
I'm using the proper model. Reading the other replies and other
websites I've realized that there is a world of applications using
semantic web technologies (soprano in KDE, Tracker in GNOME, etc...).
One milestone of this program would be to implement a sparql endpoint
to share information.

I would like to share more ideas. Tags are not the main problem in my
project. Topics, Collections and other Things keep me very busy too.
But I'll leave them for next mails.
