[jira] [Created] (ANY23-1) Error on prefix conflict in sesame
RDFWriter
Error on prefix conflict in sesame RDFWriter
--------------------------------------------
Key: ANY23-1
URL: https://issues.apache.org/jira/browse/ANY23-1
Project: Apache Any23
Issue Type: Bug
Reporter: Lewis John McGibbney
It seems there are no checks whether the RDFWriter receives different URIs associated to the same prefixes. This can introduce errors and must be further investigated.

Hi Peter, unfortunately no I don't have an example. The issue was exported from the google code issue tracker and I did not initially open it so don't have accurate information on it. I'll try t work towards finding the bug though, a use case is essential here.

[jira] [Commented] (ANY23-1) Error on prefix conflict in sesame

Peter Ansell commented on ANY23-1:
----------------------------------
I would say that this is not a valid bug unless someone has a concrete example. Internally the org.openrdf.model.URI interface is not able to attach itself to prefixes. Basically, once the URI object is created it is independent of the prefixes in the document that it was derived from. To persist the syntactic-sugar-prefixes, you need to manually copy them into the writer. The writer then writes the URI using its prefix map, which could be different to the one that was used to parse in the document which created the prefix, but will be consistent, and will not introduce errors in the RDF triples that you could source from the representation.

----------------------------------
Do you have an example of this? Is there a Sesame bug open about this issue as it sounds quite serious.
