Subject [jira] [Commented] (CLEREZZA-540) GraphNode provider service
Date Sat, 21 May 2011 16:38:47 GMT

    [ https://issues.apache.org/jira/browse/CLEREZZA-540?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13037413#comment-13037413

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

I think I meant the WebProxy which has been deleted here and moved elsewhere.

http://svn.apache.org/viewvc/incubator/clerezza/trunk/parent/rdf.storage.web/src/main/scala/WebProxy.scala?view=markup&pathrev=1124453

So clearly this is something that has arisen out of the need for a WebProxy. The WebProxy
was made into a TcProvider, in issue
CLEREZZA-531 after a long debate linked to there on what the names of graphs should be. It
seems that this ad-hoc graph naming is leading to this spagetti monster here which checks
the following providers:

- UserManager: the only implementation of UserManager requires a TcManager
- WebIdGraphsService: also requires a TcManager
- PlatformConfig: requires TcManager
- ContentGraphProvider: requires TcManager
- TcManager

So it looks like each time we create a new object type we are going to increase the if-then
statements in this class.

> 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.
> Note: it ois left to possible subsequent issues to connect this to the ability manually
refresh caches pertinent to a resource  on demand.
