Just to add: I would also object to ii, because it would exclude
locally developed ontologies that are precisely aligned with some foundation ontology
maintained in the OOR and therefore highly reusable and integratable with
I’m not sure what ‘transparent’ in iii. means.
I would include as a metric of an ontology how well documented it is. As
a crude first approximation, the average number of words in the comment field of
each ontology element might be calculated, to give potential users a guess as
to how difficult it will be to guess the intended meanings of the ontology elements.
The more documentation, the better. Of course, better organized
documentation is also better, but harder to find a metric for.

misrepresented your position.
We are discussing the scope of the OOR, thus the minimal requirements an
ontology has to meet.
Peter Yim and Ravi Sharma suggest the following:
(i) the ontology is based on open standards AND
(ii) an ontology that is created and maintained in a cooperative process
that is, in principle, open to everybody who wants to participate AND
(iii) an ontology that is created and maintained in a transparent
(iv) the ontology is accessible to all who can be identified or
authenticated (at least Read only) AND
(v) the ontology is available under a license that includes virtually no
restrictions on the use and distribution of the ontology.
[I assume that a standard is considered to be "open" if and only if
meets analogs of criteria (ii)-(v), FN]
Matthew West objects to (v).
Pat Hayes objects to (ii) and (iii).
For clarification, I don't object to (ii) and (iii),
but I do think that these should not be required. Insisting on any
conditions on the process that gave rise to the ontology adds a considerable
burden both to the cost of creating an ontology and to the task of checking its
credentials, and is completely irrelevant to the users of the ontology.
Very few, if any, extant published ontologies fully meet conditions (ii) and
(iii) above. Ontologies are not standards: they are more analogous to pieces of
software. No software has ever been created by a process satisfying condition
I agree: why should the effort of a lone wolf be kept
BTW, consider that there is no real lone wolf in the
ontology wilderness: all of us are actually working on the basis of previous
work, which is a (weak?) form of collaboration. What is otherwise scientific
