Elie Roux updated JENA-1377:
----------------------------
Description:
Model.isIsomorphicWith() treats language tags in a case-sensitive way, which is
against BCP47 spec. It is easily shown with an example:
Model m1 = ModelFactory.createDefaultModel();
Resource r = m1.getResource("http://example.com/resource";);
Property p = m1.getProperty("http://example.com/property";);
m1.add(r, p, m1.createLiteral("example", "zh-Latn-pinyin")); //
canonical
Model m2 = ModelFactory.createDefaultModel();
r = m2.getResource("http://example.com/resource";);
p = m2.getProperty("http://example.com/property";);
m2.add(r, p, m1.createLiteral("example", "zh-latn-pinyin")); //
lower case
System.out.println(m1.isIsomorphicWith(m2));
prints false, while it clearly should print true. Related bug (which is not
really a bug per se, just a trigger for this one:
https://github.com/jsonld-java/jsonld-java/issues/199
See also https://issues.apache.org/jira/browse/COMMONSRDF-51 for some
consideration of the language tag case.
