I am proud to announce the first release of the
shared-desktop-ontologies package. This package contains the core
ontologies such as RDF or RDFS and all Nepomuk ontologies that are used
in KDE, Strigi, and Tracker.

https://sourceforge.net/projects/oscaf/files/

I hope that soon all projects will remove their local copies of the
ontology files and depend on our shared ontology package.

Be aware that kdelibs will start depending on this package shortly.

Cheers,
Sebastian Trueg,
for the OSCAF team
