Peter: (01)
This might be a topic to take offline. I don't know if the conveners of
the Ontolog Forum ever actually made an enumerated list of acceptable
licenses to define "open" or have passed judgement on them. (02)
IMHO, MPL is fine but there are a host of others. (03)
The only caveat I see here is that the license is declared at the
"project" level. Assuming a hereditary model, that should cover all
pieces of the project but seasoned developers usually place the license
statement in each class or resource such as done here: (04)
http://svn.apache.org/viewvc/webservices/commons/tags/axiom/1.2.13/src/main
/assembly/bin.xml?view=markup (05)
I'd be willing to help on this if you wanted. (06)
