User BNodes - why  not with UriRef ?
------------------------------------

                 Key: CLEREZZA-199
                 URL: https://issues.apache.org/jira/browse/CLEREZZA-199
             Project: Clerezza
          Issue Type: Improvement
            Reporter: Oliver Strässer
            Priority: Minor


It will be easier for the developer, if the user nodes are not BNodes . 
The clear node reference with an UriRef helps, if I want to connect GraphNodes in  a seperate
graph, with an user. 

example: 

Nodes with the type ClipFeed are stored in a graph called "http://tpf.localhost/clips.graph".
Now I want to save the creator of the feed - so that I can show the personal feeds of the
current logged in user. 
To reach that, its necessary to save the triple   " clipfeed - dcterms.creator - user resource"
in the content graph (all other properties of the clipfeed  are stored in the graph http://tpf.localhost/clips.graph)
if I wouldn't do that, the reference between the clipfeed and the BNode of the user is lost
 after a sytem restart (because the user is a BNode).

If the user node has an UriRef, I can save the Triple about the user in my own graph. 


If you need more examples - ask me - I have more...


So the question is: Why you don't save the user node with an UriRef example: http://tpf.localhost/user/df6f91c5-71e2-4b80-804f-2d09abda642a
- it's a small change with a big benefit
