Hello Guenther & others

We have also done an OWL-implementation of the CIDOC-CRM 4.2 for our own
use. We also have a separate version that includes the latest version of
FRBRoo. Obviously I would be interested to participate in a co-operative
effort to arrive to an official OWL rendering of CIDOC-CRM and FRBRoo.

It might be a good idea to publish draft versions of our efforts on a closed
wiki (=requiring login & authentication) and then have a mechanism for
on-line annotation.

We have used Protégé 3.2.1 in our work, so our version can be opened with
Protégé. One option could be to distribute Protégé-versions and collect
annotations in a wiki.

Best regards,
Mika

toDOLCE-Ultralight PLEASE RESPOND

Dear colleagues,

a while ago I wrote to Aldo whether he will continue to work on an OWL
version of the CRM aiming at an upgrade to version 4.2.  At that time
he answered that he was not planning to do that and he sent me the
results of his work on version 3.4.9 to use it for further development
if we like to. I  talked to Martin about that, expressing our interest
to pursue this issue further, but of course avoiding duplicate work.
Martin said that he was not aware of any other group --- including
FORTH ---- already implementing or planning to implement a new OWL
version in the near future. So, we looked for a student and finally
found one who started to work on with a new implementation of 4.2 in
OWL as a study project several months ago.  Now, he is nearly finished
and of course we will make the result of our work --- OWL code and
documentation (in German, sorry) --- available to the community as
soon as it is ready.  Furthermore, we are planning to present it at
the Nuremberg workshop.  So,  I was a bit surprised by Aldo's  last
message --- obviously communication in our community is sort of
suboptimal.  Of course, I strongly support any effort to integrate
everything what has been done so far. Perhaps we should use the
Nuremberg workshop to set up a subgroup aiming at the implementation
of a reference version 4.2+ in OWL; obviously there are several issues
we have to agree on: problems in the current 4.2 document,
representational alternatives, alignment with DOLCE, etc.
Furthermore, we should nominate a coordinator to avoid duplicate work
in the future.

Best regards,
-- Guenther
