Firstly, thank you for the prompt and useful reply to my previous
post.
I am exposing my d2rq-generated ontologies with the built-in Ensemble.
All work bar one, and this one generates a message in the browser, but
this is clearly an exception handler for this trace in the log file.
Please can you advise? I thought was looking for rdfs:label, but this
all looks OK from inside TBC.
Peter
