Re: Expensive links in Linked Data

F-P, there's a bunch of work on describing expected computed triples in a Linked Data context; see Linked Open Services, Linked Data Services, RESTdesc, etc.

Thanks,

no, this doesn't solve the problem. A user gets ex:e0 (the "cheap" resource). 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)

Best,
