Indeed ... actually this kind of endpoint is rather intended for 
machines sending queries under the hood than for humans.

You mean that IVOA data/identifiers should stand as "professional" 
references in their domain, and other data about the "same" objects 
should re-use those identifiers, right? In other words it would be up to 
http://dbpedia.org/page/Denebola to use IVOA identifiers than the other 
way round. Of course it makes more sense this way.

Well, not sure about that. Google will suck your data as soon as they 
are published whatever their format and quality, and manage to add them 
*using their own format* to Google sky if they wish to do so. Don't 
worry about them. They don't care about declared semantics, they think 
their own algorithms and heuristics are more powerful. The problem is 
that they are not open. Even if your data are reused by Google sky, you 
will never know how.
I would say linking to Wikipedia (through DBpedia) would be a proof of 
concept. Or as said above the other way round, for DBpedia to be able to 
link to IVOA.

No?
