I tend to agree that we should modify ii. It is generally better that
ontologies are built by small terms (including single-member teams).
But then generally, I think, maintence should allow a more open process. (01)
We tried to define a metric for intelligibility of ontology elements here:
I think 'transparent' in iii. is intended to mean: the ontology
development process is publicly documented e.g. by being carried out
through use of email fora which are web-accessible to all. This is
the policy maintained for example by the OBO Foundry (http://obofoundry.org).
