Like Stan I was hoping for something that was more accessible that
allowed for open participation in the process. Even tools like web
protege are too complicated from what we need to achieve. A 300+ page
OMG metamodel specification is not a good place to start.
I was also thinking of something based on DCMI made available via a
simple editable tabular structure using the TDWG wiki. A Poor man's
RDFS to function as a common repository and cross reference for our
Ontologies. One concept per page using the wiki page graph to
establish relationships. Extraction from this place to Metamodel
compliant implementations or to application level schema should be
trivial. The aim being to turn the process around so that those of us
required to work at the more esoteric end of this spectrum are aware
of and building against community level requirements.
I personally believe this to be within our current capabilities and
certainly achievable before the next TDWG meeting.
