I wouldn't assume anything about Tracker's capabilities since they are quite a 
fast moving project.
They've switch to using Nepomuk ontologies and Sparql as the query language, 
they use the same library for extracting file metadata (streamanalyiers 
originally written for Strigi), they have a D-Bus based client which can 
retrieve mail related data from mail user agents supporting that D-Bus API. 
etc.

There are probably differences in resource usage, speed, maximum query 
complexity, etc. when compared to Nepomuk-KDE, but that would have to be 
evaluated in the context of the target scenario in order to see if these 
differences have any significance.

The value of Nepomuk-KDE for developers is probably mainly its high-level API 
so one doesn't have to build sqarql queries manually, the convenience APIs 
like ready to use widgets (e.g. rating widget) and data integration such as 
with Akonadi (e.g. allowing queries that find person related contacts, 
calendar entries, mails from/to/about, etc).

The last point (data integration) can of course also be achieved with Tracker 
provided somebody implements it, so the value right now is that it already has 
been implemented for Nepomuk-KDE.

Cheers,
Kevin
