interlinking LODD datasets @ OAEI 2010

Hi,

I am preparing a data interlinking track for the 2010 edition of the 
Ontology Alignment Evaluation Initiative. It's the second year we will 
evaluate instance matchers [1]. This year we would like to try finding 
links between LODD datasets. The participating systems should be fully 
automatic, unlike semi-automatic tools like Silk.
I'm writing here to ask about which datasets you think are the most 
interesting for such a challenge, which ones have the best quality 
linksets that we could use as gold standards to evaluate matchers.

Cheers

François
