Why introduce a non-canonical NIR identifier and yet another sameAs link? There's no need to include a complete description when you resolve the identifier, a seeAlso IR link would suffice (wouldn't it?)

Hi Francois-Paul,

how about that solution:

You publish the "cheap" data about your entity under 
http://example.org/e0, which is the "official" URI of that entity:
ex:e0 owl:sameAs ex:e0expensive
ex:e0 :cheapProp ...

And under http://example.org/ex:e0expensive, you publish
ex:e0expensive owl:sameAs ex:e0
ex:e0expensive :expensiveProp ...

So people following links in LOD will always land at a page without the 
expensive properties, and those who really want to know can follow the 
sameAs link.

Does that solve your problem?

Best,
Heiko

A property, let's call it :expensiveProp, has this class as domain, and you know that computing or publishing the corresponding triples is expensive. In such a case, you don't want to produce these triples each time one of your entities is accessed. You want to include in the representation of your entity only a link to that information.
