Is there real world RDF-S/OWL instance data?

Dear All,

As an argument to stress the importance of the Semantic Web and as 
example data to evaluate tools it would be nice to have a library of 
real world RDF-S/OWL instance data available. My impression is, that 
there are many schemas around, but it's harder to find real life 
instance data. This might be due to copyright issues or the fact, that 
the borderline between classes/schema and instances/data is not always 
clearly marked and some projects rather use a representation as classes 
than a representation as instance data.

So, if you know of RDF-S/OWL instance data which is publicly available 
and shows an interesting application please let us know. I'm especially, 
interested in the impact of its usage. ;-)

The following is interesting Semantic Web data I know of:

* Wordnet - a lexical database for the English language [1]
* UNSPSC (Universal Standard Products and Services Classification) 
representation as classes [2]
* Wikipedia in RDF [3]
* Open Directory DMOZ in RDF [4]
* Open Bio-Medical Ontologies in OWL (rep. as classes) [5]
* FOAF - Friend of a Friend (many small instances available on the Web) [6]

I will summarize all statements and post it to the list again and maybe 
create some wikipage for persistent reference.
