Simon and I have been working on two Enterprise Ontologies lately. While we’ve both been involved in both of them, he took the lead in reducing what we’d learned to the model for one, and I the other.    Without prior agreement, we each took different routes to the process first design. I rounded up all the properties that had come up in the course of over a dozen interactive elicitation sessions, and decided to start there. I thought if I could rationalize them and reduce their number, surely that would be a route to elegance.
