Thank you very much for the references.
A first work dates back to 2006:
Vrandecic D., Gangemi A., “Unit Tests for Ontologies”, M. Jarrar (ed.) Proceedings of OnToContent, OTM Conference, Montpellier, Springer, 2006.
The work presented here is very interesting as is the link in the paper pointing to the Protégé plug-in. Is the unit testing work still active in your lab and implemented in software?
Thank you for the link. I find design patterns useful for development and engineering work and am glad to find the website. Some of the concepts seem similar to those presented in John Sowa's top-level-categories. Is there an effort to reconcile the patterns with other work in philosophy or knowledge representation?
