the Nepomuk ontologies and query system are being standardized and will be=

replacing the role(s) that xesam was trying to fill. it's rather complete=20
system (from the semantics side of things) and has a _lot_ of work put into=

by a number of very dedicated and knowledgeable individuals. KDE is already=

been instrumenting several of our applications to feed into Nepomuk, not le=
ast=20
of which is akonadi fro PIM (email/calendaring/contacts/etc). if it all=20
possible, it would be great to zeitgeist be able to work with the Nepomuk=20
ontologies and stores.

that said, it'd be pretty cool to see a zeitgeist widget written in Qt/KDE.=
 so=20
to your original question:

"I was wondering where I should start in making the widget so I thought id=
=20
ask."

from a UI POV, you could dive in with PyQt/PyKDE (iirc zeitgeist is written=
 in=20
Python, correct?) and should be able to get up and going in very little tim=
e.

if you would like a place to house it, we can certainly get you svn access,=
=20
though i imagine it could be hosted with the rest of zeitgeist even easier.

as for loggers ... that will be a bit more complicated i think as it will=20
really require instrumenting a large number of applications, each with thei=
r=20
own internals. this is, in part, why we chose to go with Nepomuk: it gives =
us=20
a common target, it's platform neutral, it's a complete solution that other=
s=20
can also tap into and it is the result of an EU funded project so there's g=
ood=20
science behind it.

i would guess that it's much, much less work (and far more likely to succee=
d=20
with upstream) to simply allow Zeitgeist to use Nepomuk stores than it woul=

be to go around and write loggers for enough applications for it to be=20
interesting to use. you can then just let the app devs provide support for=

their own apps via Nepomuk :)
