Re: Expensive links in Linked Data

OK, I see.

Then a possible idea could be splitting the dataset into a cheap dataset 
and one (or more) expensive datasets, interlinked by sameAs links. If 
you include a VoID description [1] of all datasets with each of the 
datasets, you can inform the user about what properties to expect when 
following the links.

Best,
Heiko

Though she can see that there is the link to the "expensive resource", she doesn't know the meaning of the link (it is just an owl:sameAs): she doesn't know what this is about. (Note also that there could be several expensive properties)
