I renamed this thread as the topic had drifted somewhat...

Sharing *is* related to ownership... so I have a dilemma for y'all at 
this Christmas.

If  building ontologies is hard work, (which it is by all accounts), 
then I wont do it unless I can see a benefit.

Pat assumed that it is a developers interest to share ontologies 
maximally, as that is the way that people benefit; but I want to offer 
a counter:

If I am a large customer (how about the largest customer in the world 
for a start) then it *is* in my interest to ensure that my suppliers 
are on board with me by using the same ontology. Vice-versa of course 
for large vendors.

However, it is definitely *not* in my interest to help my competitors. 
So, I will want to shut them out of the benefits of my hard work.

One way to do this is by differential licencing: I make it easy for my 
partners to licence my stuff and hard for my competitors to do so.

If you think this cannot happen, consider the situation in a sister 
organization wrt orchestration :). The differential licencing situation 
is potentially so severe in that case that I strongly recommend my 
employer to steer well away.

Now, what is the most productive stance to take on this? Should we 
throw up our hands in horror and bemoan the power of monopolies? Or 
should we embrace it; as a way of harnessing a powerful force for 
progressing interoperability across organizations?

P.S. To paraphrase Churchill:

young(X) & !socialist(X) => ! have_heart(X).
old(X) & !tory(X) => !have_head(X).
