Subject [jira] [Commented] (CLEREZZA-540) GraphNode provider service
Date Sat, 21 May 2011 17:32:47 GMT

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.

refresh caches pertinent to a resource  on demand.
