Hi Tomas,
Since your project includes Semantic MediaWiki specifically, SMW actually
has a repository for just such a thing - see here:
http://smw.referata.com/wiki/Category:Packages
As you can see, only one such "package" has ever been created - you can see
its homepage here:
http://wiki.creativecommons.org/CcTeamspace
It was created in 2008, and is significantly out of date. Still, it was
done nicely, and it's a good example for how such things can be put
together. (And it did get a good amount of use in its first few years.)
