This is nice of you. 

Rather than sampling the data, I have zipped it and posted it on my
personal web site at  http://ghazzaoui.org:443/Mulgara/ 

There are two sets of data. The difference between them is that one uses
literals like this: 

         "cel00010"^^<http://www.w3.org/2001/XMLSchema#string> . 

Whereas the other does not specify the literals' types: 

         "cel00010" .

The original data that was given to me includes explicit types for all
strings and integers and doubles, but I wanted to try without just to
see if that was causing the problem. 

As for the iTQL that I posted up there, the file names should be
self-explanatory but please do ask me if you have any doubts.

Hi Ramez,

OK, I'll have a go at it here as well.

So I know we are trying the same operations, could I get you to send  
me a small sample of your data please?  I have a copy of your rules,  
but I'd just like some of your base information that you expect to run  
the rules on and get an inference from.  It does no good if I succeed  
with my own data if it doesn't match the data that is causing problems  
for you.
