xsd:anyURI is sameValueAs an xsd:string or simple literal
---------------------------------------------------------
Key: JENA-148
URL: https://issues.apache.org/jira/browse/JENA-148
Project: Jena
Issue Type: Bug
Components: Jena
Reporter: Andy Seaborne
Priority: Minor
Attachments: Jena_AnyURI_r1190400.patch
In the memory model xsd:anyURI matches in Graph.find an xsd;string with the
same lexical form.
"http://example/"^^xsd:anyURI matches "http://example/"^^xsd:string and
"http://example/";
This is because the value returned by Xerces is a Java string and isEqual in
XSDDatatype is based on equality of Xerces value regerdless of datatype to
account for derived types.
The proposed solution in the patch is to have a new XSD datatype that uses the
BaseDatatype isEquals machinery which makes equity "same datatype, same value".
Also applies to xsd:QName, xsd:IDREF, xsd:NOTATION
