We/Jena have to manage the transition anyway as persistent data is affected by RDF 1.1 (for simple literals => xsd:strings). RDF.rb also maintains the language as originally provided and normalizes when doing comparisons. That means that when adding two literals that differ only in the case of the language, the first one added to a repository wins. The various serializers just reproduce what was originally input, unless output is set to normalize, in which case the language is set to lower-case. Language-tagged literals are always given the rdf:langString datatype, per RDF 1.1. > Andy > >> >> - Sandro >> >> >> > >
