Re: License File for Open Source Repositories

[Nadeau Thomas <[e-mail]>]

	I have no issues with the license text, but will suggest a clarification or
two. We have been using basically the same text for IETF models on the Yang repo on github for about 
2 years with no issues.   I’ll note that that we hashed through these in great detail with the 
netmod/conf community and arrived at how we operate. We also work with the IEEE/MEF/ODL communities
on the same repo, and everyone seems to get along happily with these rules in place. The license 
statement we have been using for about 2 years is available here if you are interested.

	https://github.com/YangModels/yang

	The first clarification I think is necessary is around how “repository” is
defined. In the case of github, that might be taken to mean the *entire* repository, which
practically speaking is not how things work, at least in our case because the repository 
holds files created by various organizations (and vendors for that matter). Instead, the approach we 
have taken is to require that each main/top-level subdirectory contain a license statement
that applies to all files and subdirectories therein. Committers explicitly agree to those terms
by virtue of checking in a file (or posting a comment/issue on that file).

	This also reveals a finer point about the license statement pertaining to comments.
Again, our statement defines comments as falling under whatever licensing terms are defined
for the file in question.  This is a gray area in our case due to having multiple files that fall under
multiple licenses. So for example, one comment about one file might refer to another file covered by 
another license.  Does that mean that now the first file falls under the licensing terms of the other
file?  Let me give you an example. We have IEEE models that do rely on advice given from Yang doctors 
either explicitly or via references to some of the guiding documents/RFCs that exist. In discussing the 
IEEE model, there might be a discussion around such a recommendation for how to build a model. In this 
case, is this IEEE model suddenly now under the IETF’s license (or the part of the model being discussed)?  
The working assumption by us is that it is not. However, this is something you might want to clarify.
