Andy Seaborne commented on JENA-319:
------------------------------------
I think this is a good point for JENA-189 (Jena3 /technical).
None of the API calls resolve IRIs nor require absolute IRIs. It's historical
- addNamedModel simply follows what all the API calls do.
The same happens with
SELECT * { <s> ?p ?o }
SPARQL parsing will resolve <s>, but createResource("s") does not.
Resolving isn't complete straight forward (or cheap). API calls can be
expected to be much higher frequence than SPARQL queries.
Requiring absolute IRIs in the first place as a policy is one design to follow
and personally, I favour using an IRI object, not strings, which requires
absolute IRIs. Resolution relative to the current local directory isn't very
webby.

> If dataset.addNamedModel(uri, m) is called and 'uri' does not have a colon
> the query select * { graph <uri> { ?s ?o ?p }} does not return any results
> even though select ?g { graph ?g { ?s ?o ?p }} will return the uri as ?g.
> JUnit based test case attached.
