Ontology alignment evaluation initiative

Hi,

The OAEI 2009 campain [1] might be of interest to some of us. It 
proposes an evaluation of ontology matchers. Particularly, this year has 
an instance matching track [2] proposing to find equivalent instances in 
various RDF testbeds.

Cheers,
François
