validation error

Hopefully this is the right place to point out that there's a 
validation error in tap.rdf[1]. In particular, the 4th line 
(xmlns:thiskb="") causes an error of:
     Prefixed namespace bindings may not be empty.

Which can be seen by pasting the following into the W3C's RDF 
Validator[2]:
    <rdf:RDF
     xmlns:thiskb=""
     xmlns:a="http://tap.stanford.edu/2002/05/GetDataSchema"
