Hi Martynas,
there seems to be a small mismatch between the IRI spec and the RDF
Spec. We are investigating this ourselves. In general it seems that some
parsers are switching like Rapper/Libraptor from version 2.0.14 to
2.0.15, but others are not.
So there is no real common ground here. The error you have posted is not
an error RDF error as RDF 'should' conform to NFC, but it is not an
error, if it doesn't:
https://www.w3.org/TR/rdf11-concepts/#section-Graph-Literal
I am actually wondering why it says NFKC and not NFC, which is the default.
We are investigating it since a couple of months, but it involves a lot
of research on spec details and there is no fast progress. Different
parser seem to adjust their behaviour. If you are lucky, you can turn
off the Jena Riot fatal exceptions with options, some versions had this
hard coded.
Maybe, you could post your riot version, this would help ...
All the best,
Sebastian

Hi,
trying to parse the RDF document from
http://dbpedia.org/resource/Tim_Berners-Lee:
org.apache.jena.riot.RiotException: [line: 146, col: 35] Bad IRI:
<http://ja.dbpedia.org/resource/ティム・バーナーズ＝リー> Code: 47/NOT_NFKC in
PATH: The IRI is not in Unicode Normal Form KC.
I would expect there to be a validator somewhere in the pipeline that
should catch this sort of errors, but evidently there is not?
Happy Holidays.
Martynas
