Henry Story commented on CLEREZZA-540:
--------------------------------------

You wrote at the top for this issue:

"Implement a platform service that returns GraphNodes for URIs. The GraphNode 
is the resource identified by that uri with as BaseGraph sources considered 
authoritative for that resource. "

I then spent one hour compiling things again, getting things to work, changing 
code, debugging, all happily looking forward to using this feature, only then 
to find that it does not do what you said it would above. It says "BaseGraph 
sources considered AUTHORITATIVE for that resource." Considered authoritative 
by whome? Ok, for some local resources I understand that mergers could be done 
but only in particular circumstances, otherwise it is going to get to be very 
difficult to understand what is going on. If you want graphs that are mergers 
of other graphs then there is work that has been done in that space such as the 
Work on Networked Graphs 
http://blogs.oracle.com/bblfish/entry/opening_sesame_with_networked_graphs

But I don't consider  node contexts to be the right solution at all. They are 
useful for sure, and I have used them recently happily. But that is not where 
one gets authoritative graphs from. Authoritative comes from Author, ie creator 
of, and that can only be aplied to a graph or sets of graphs.

Anyway I descrive above a URI I fetched, and you give me 10 times more 
resources back. I don't want those! They are not authoritative.
