[ITK Community] [Insight-developers] Remote modules License

[Brian Helba]

Hi all,

Part B of the license in question (
http://www.rad.upenn.edu/sbia/software/license.html ) is what applies to
taking their code and using it as part of an ITK remote module. It appears
at first glance to be a permissive open-source license, but I think someone
certainly needs to examine a diff between it and Apache 2.0.

I'm wondering about a possible complication from Part A, which is a
contributor license agreement (CLA) for contributing code back upstream. If
improvements to the library in question are made by ITK, it would be best
if those could be easily contributed back upstream; if we can't do this,
then the library gets forked and it's much more difficult to incorporate
updated versions from upstream. From the text of Part A, it looks as though
any of ITK's modifications, being Apache 2.0 is enough per se to meet the
requirements of their CLA. However, if their CLA requires an individual to
sign any documents (it doesn't appear to) or for some entity to provide the
code with a warranty (which section 6 does) beyond Apache 2.0's "no
warranty whatsoever", there could be problems.

Perhaps I'm being too pedantic, but it's an angle that I think should be
evaluated. For a remote module, I think ITK could include it regardless,
but it would be good to know the answers to these questions.

Brian
