That is my understanding of the term also. (02)

The first. Only the ISO has this absurd policy of
charging cash for standards; moreover, I would
not say that Matthew's interpretation of 'open'
is universally accepted. The W3C is not open in
this sense, for example. (04)

Certainly the latter. Lets take a stand on this.
It does not eliminate ISO participation, but it
does require them to make any relevant standards
freely available. They can do this, and have done
it in the past. Putting something into the OOR
should make it automatically available for access
and use without restriction; like the GNU
licences, it should not permit other copyright
restrictions to be 'passed through' its open

I have no problem with that part. We should
permit ontologies that were constructed by one
person in total privacy, or written on stone
tablets by God, as long as they are freely
available for public use without restriction.
This is what 'open' means in 'open cyc', for
