Dear Guenther,
Thank you very much for your message. Once you have invested already in
that work, would you like to further coordinate the effort? Who else?
I would not like to coordinate this.
I think the most effective way to deal with it is, as you say, to present
the alternatives, discuss the alternatives in a physical meeting in a way
that non-techies can follow what the intellectual consequences are,
and create a version for public comment for the site.
Since OWL is quite expressive and there is a growing OWL user community,
I suggest as an ISSUE to discuss, if we should maintain an "official"
OWL interpretation of the CRM.
Best,
Martin
