[Xesam] Nepomuk/Desktop/Shared ontologies - svn layout as discussed at the GCDS last week

It was Sebastian Trüg who said at the right time 13.07.2009 16:10 the 
following words:

converting a XML to N3/turtle is easy, doable online:

I suggest to use a BSD/CC combined header file (as ontologies are not 
sourcecode but a bit documentation,
dual-licensing them under BSD/CC-BY should be fine and keep everyone 
happy for the future).

Copyright is always to the individual who created the files, if the 
individual publishes the file under BSD/CC, then the name of the 
individual is kept.
We had a long discussion about copyright, and Sebastian said that it is 
unrealistic to require people to transfer copyright (or relicensing 
rights) to OSCAF, so the individuals write their own name into the files.

I think I already wrote the license headers, but can't find them, so 
again, I wrote the license header we should use here:
https://sourceforge.net/apps/trac/oscaf/wiki/License

if you disagree, change this wikipage and send us the reason why.
