sorry, maybe that was incorrect,  I took the word validators from third tab
on this
page

 http://pedantic-web.org/

I personally have limited experience with RDF
but  I remember once one of the RDF elements (fields? properties?) was
supposed to be a URI
but the RDF generator we used did not specify it had to be uri, so we
entered a word (literal?)
and validation failed, when a valide URI was entered, the RDF validated
I am sure the pedantic people will have compiled a catalogue of reasons why
validation fails?


hope I address your questions
