One thing that propably will confuse people here is that often when they
deal with there files/objects, the line between what might be a tag and
what might be a topic is very blurred. You may separate these two by
definition, but can you base a user interface on this kind of abstract
thinking? User interfaces should be very easy to grasp for everyone
after all.

You suggest that the names of the people on a photo might be tags. Many
people propably wouldn't intuitively consider names as "a property
observable by all". Often the names of the people on a photo may be the
only thing that just you know (for example two of your friends standing
on Trafalgar Square).

For many objects you just couldn't name just one topic. Often there's
not one main characteristics for an object, but many of them. If you
keep on thinking which one is the main characteristics, you get a
headache. Isn't the current Epiphany bookmark system largely based on
this observation?

Sorry, have to stop - I'm beginning to get a headache :-) It's good that
you are trying to clear these things up. I hope my short reply helped at
