-------------------------------------
Summary: RDF/XML parser incorrectly disallows some Unicode
characters
Key: JENA-394
URL: https://issues.apache.org/jira/browse/JENA-394
Project: Apache Jena
Issue Type: Bug
Components: RDF/XML
Affects Versions: Jena 2.10.0
Reporter: Richard Cyganiak
Attachments: katakana-middle-dot.xml
The Unicode character 'KATAKANA MIDDLE DOT' (U+30FB) in the local part of a
property name causes a parse exception in the RDF/XML parser. This seems to be
incorrect, as the character is allowed in IRIs and is allowed in XML local
names, as far as I can tell.
Example file:
<?xml version="1.0" encoding="utf-8" ?>
<rdf:RDF xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#";
xmlns="http://example.com/ns#";>
<rdf:Description rdf:about="#this">
<隣接自治体・行政区 rdf:resource="#that"/>
</rdf:Description>
</rdf:RDF>
The offending character is the “dot” in the middle of the property name.
