hexBinary whitespace issue
--------------------------
Key: JENA-170
URL: https://issues.apache.org/jira/browse/JENA-170
Project: Jena
Issue Type: Bug
Components: ARQ, Jena, RDF/XML
Environment: 2.6.4
Reporter: Henry Story
As I understand, initial and final white spaces in xsd:hexBinary in xml should
be ignored
http://www.w3.org/TR/2001/REC-xmlschema-2-20010502/#hexBinary
because of the whitespace facet.
With Jena 2.6.4 this is not the case, as shown by the test below.
I found that in Clerezza when using the graph api, so this is a problem even
when one does not use SPARQL.
Removing the white space solves the proble.
xsd:hexBinary is already a very fragile encoding. Making it this fragile is
bound to lead to issues in communication.
The same is true with the N3 encoding.
