[jira] [Commented] (JENA-132) N3 / TURTLE serializers ignore relative URI

["Andy Seaborne (Commented) (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/JENA-132?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13123693#comment-13123693 ] 

Andy Seaborne commented on JENA-132:
------------------------------------

The output from the TTL writer is correct RDF - it just has not used the base URI to abbreviate the data.  It's the same triples.

The output files from the TTL writer are a failthful representation of the triples and are fully portable (i.e. the RDF will be read the same where ever the file is read from). Some people would argue this is the better behaviour to the relative URIs generated by the RDF/XML-ABBREV writer.

A contribution to enable the writing of relative URIs by the TTL writer would be good.

Reclassified as a feature request.
