Agenda

Licensing Terms for Gazelle Project

1. Apache 2.0 or Eclipse License?

• Considered differences between two licenses:
  • Apache 2.0 is more "permissive" in the sense that it poses minimal restrictions on redistribution and distribution of derivative works: Requires attribution only
  • Eclipse license is more restrictive (or "viral") in that it requires all derivative versions ("additions" and "modifications") to be released under the same Eclipse license
    • Eclipse does make allowance for "modules" that are distinct from "the Program" and that can be release under separate licensing terms
    • Would introduce the problem of sorting out what contributions were the Program vs modules: Everything on INRIA forge constitutes the Program?
  • Even the "attribution only" model might prevent some contributors from putting their code on the forge (eg, NIST)
  • Difficult to determine whether additional restrictions of Eclipse license would pose an obstacle to contributors, but this does seem possible
• Voted on the current committee members' preference between the two proposed licenses:
  • Apache 2.0 was the preferred license selected (Apache 2.0: 2 votes; Eclipse: 1 vote; 3 abstentions)
  • Action: Chris will announce outcome to the committee list and invite any objections/alternatives before moving forward with contributor agreements, etc. based on the license

Contributor Agreements

Reviewed David Monteau's INRIA draft agreements for:

1. Corporate Contributors
2. Other Entities
3. Individuals

• Question whether it is essential to have separate agreements for corporations vs. other organizations: need to review the differences
• Question about whether allowing individual contributors is advisable
  • Their contributions might have to be removed from the code base if there were a dispute with their emplyer
  • Individual contributors would not be eligible for membership on the Testing and Tools Committee: governance specifies that all committee members have to serve as representatives of IHE member organizations
• Apache 2.0 licensing agreement includes its own contributor agreements: Assuming decision to go with Apache 2.0 license is confirmed, committee should consider using the Apache contributor agreements
• Action: Committee should review INRIA agreements and compare with Apache 2.0 agreements

Committee Governance

Deferred to April 28 tcon
