well, my first attempt lead to reindexing my files with baloo
I diden't want that because I would really like to stick with GNOME.
dolphin can't (at least on first sight) use the tracker store.
I was hoping I could keep tracker as backend and use dolphin to browse
and search and (most important for me) to edit tags.

even in this very short time I started to really like dolphin.

of course you may :-)

I very much like the idea of a semantic desktop.

Having all your data dynamically grouped or structured by different
(combineable) criteria, e.g., (self attached or automatically extracted)
tags, timeline, type, location, etc. is really the way I would like to
organise myself.

unfortunately the (as of today) useable tools, that go in that direction
are still quite far away from this vision.

SWAP is just one of so many academic projects ...
by chance I had a tiny part in this one ;-)

Another project I worked with, used to calculate a semantic distance
between documents and graphically arranged them according to this
distance. So if you selected a document, the "closest relatives" based
on a changeable set of criteria were grouped near it, others further
away in a hyperbolic tree http://en.wikipedia.org/wiki/Hyperbolic_tree.
This one was an internal project at Dresdner Bank, so it is not
available to the public.

So that was a little trip on my motivation behind this discussion ...
