Yes, there is. I may have come across in the minutes as an "OWL 
skeptic", since I was the only one opposing the view that the group 
should spend time on it but really, I'm not. It is just that we've used 
some pretty simple reasoning in a commercial solution, and we didn't 
really get the performance we wanted and thus concluded it is still 
hard to sell, and therefore other matters should be prioritized. 

I think that the whole range of ontologies, from the informal SKOS 
thesauri to the formal rigorous OWL Big-O ontologies makes sense for 
different things, but that one should be aware of strengths and 
weaknesses for each application, and that some things may take a couple 
of years to "get there".
