RDF/XML parser fails to parse datatyped empty strings

Created: 05/Apr/05 11:44 AM Updated: 11/Apr/05 01:52 PM

Component/s:

RDF/XML parser

Affects Version/s:

1.0, 1.0.1, 1.0.2

Fix Version/s:

1.0.3

Description

Bug originally reported on the forum: http://www.openrdf.org/forum/mvnforum/viewthread?thread=525

Related error in RDF/XML specification reported on www-rdf-comments mailing list: http://lists.w3.org/Archives/Public/www-rdf-comments/2005AprJun/0000.html

The RDF/XML parser in Rio/Sesame fails to parse the following data fragment:

...
   <rdf:Description rdf:ID="ID1">
       <foo:prop rdf:datatype="http://www.w3.org/2001/XMLSchema#string"
       ></foo:prop>
   </rdf:Description>
   ...

Although the RDF/XML specification indicates that this is indeed an illegal piece of RDF/XML, the general consensus seems to be that this should represent an empty datatyped literal. The Turtle equivalent of the literal being ""^^xsd:string.
