Of course. If you can read a file, then you have that file in
your computer. At which point you can do anything to it you
want.
It makes sense to me to attempt to define
degrees of opennes in ontology in the same way that perhaps a gpl or
creative commons license defines what can a person do with content and
other products of the mind (attribute, reproduce, distribute,
commercialise, rip, repurpose, change, or not). If Ontology, or some
parts therof, or some versions thereof, can be considered
'intellectual property' of sorts (some people dont like that
term at all) then everything that applies to a creative commons
license or gpl is likely to apply to open ontology, and the
repositories that follow
All true, no doubt. Ontologies in that respect are just like any
other text or image. I don't mean that this issue is irrelevant, but
that there is nothing particular to ontologies as such which is
relevant here.
Pat, maybe ontologies cannot be compiled
and executed, yet, but reasoners, when properly constructed
(....) control and provide inputs to executable
programmes, right?
They can, yes. What is your point?

That you can read it, exactly. In contrast to
most bought software, where what you get is not
the code in readable form, but a compiled
executable, which you can run but NOT read.

And then its not open source. Its the source that
is open, not the code. But this distinction
doesnt apply to ontologies since (AFAIK) they
don't get compiled to executables.
