Hi Stephen,
There’s not really enough information in the error you’ve given below for me to
work out your problem. It looks like your posted text is cut-off.
I’m assuming you get no error when parsing the ontology itself, i.e. this line:
> g.parse('definitions/HR_Reference_Ontology.xml')

The way you’ve posed the query to the graph is correct:

The loop loos correct too:

So, it looks like the only issue you have is that there’s an error with your
SPARQL query. If you can post your query here, perhaps we can have a look at
it. Just note though, actually working through your SPARQL query is a little
off-topic for rdflid questions as it’s really about SPARQL, not the rdflib
library.
Regards,
Nick
