Dear all, let me suggest a two-stage process:
- Up to the meeting in Nuremberg next December, we, i.e. Bernhard Schiemann and myself, are ready to volunteer in terms of collecting all recent OWL implementations of the CRM, making them available on a web page --- including documentation, if available, and starting a moderated Wiki about this subject. - In Nuremberg, we should have a special session on CRM/OWL in order to review what has been achieved so far and to set up an organizational and technical framework aiming at a coordinated standardized OWL implementation. We should find a coordinator for this task, who is also ready to take care of maintenance and updating to future versions of the CRM. - Everything related to the CRM is being hosted by FORTH and I don't see any need to change that. Up to December we will offer a quick solution on our website, but later on FORTH should take responsibility. So, please, send everything related to CRM/OWL to us (or, better, send a link). Of course, we got Aldo's code through the links he sent already, and I think Detlev Balzer's version is already avaiable on the FORTH web site (so there is no need for duplication, if there haven't been changes since then). And please let us know whether you are interested in a moderated Wiki as suggested by Mika. Best regards, -- Guenther On 6/15/07, Detlev Balzer <d...@dbalzer.net> wrote:
Dear all, this is great. So I'll throw in yet another OWL representation that I have done in 2004 (and which it is a bit aged by now), for discussion and comparison: http://cidoc.ics.forth.gr/OWL/releasenotes349.html I agree with Martin's suggestion to nominate a coordinator and I'd be happy if Günther Goerz would volunteer for this effort. -- Detlev P.S.: Apparently, this situation is not too unusual: The MPEG-7 community has managed to produce four or five OWL representations of ISO 15938-5 largely independent of each other. And all of these had even been described in journal and conference papers.
