Hi Tom,

sure, in an ideal world we could just point to the rdf data in other
sources. Unfortunately, we're not quite there yet...

Integrating data includes data cleansing, schema mapping etc., and if we'd
just publish the mapping and cleansing rules instead of the cleaned data,
then the rdf client would need to execute those rules. I doubt that would
really work...

Yes, of course. It was just an example since currently owl:sameas statements
are included into the datasets and hence licensed under the same license as
the dataset itself. 

It would seem a bit strange to me to put every sameas triple into a separate
document and link from the "data"-rdf to that sameas-document. That's why I
asked to a solution to publish the sameas triple in the same document along
with the "data", but attribute a different license. 

Cheers,
Georgi
