Hello,
I work in the tech transfer office at the Princeton Plasma Physics Lab
(PPPL), a DOE National Laboratory, and I have recently taken up a
stewardship role over the lab's software portfolio. I am in the process of
ensuring we are compliant with our contractual obligations to the DOE in
how we obtain permission to copyright software, so there are a number of
"legacy" codes at the lab being open sourced in addition to anything newly
authored by our developers. My colleague Chris Wright has prepared a
preferred license for this process, a variant of Lawrence Berkeley National
Lab's BSD-3 license (https://opensource.org/license/bsd-3-clause-lbnl) with
PPPL's name substituted. We would like to have our license officially
approved by OSI to encourage its use when our developers decide to open
source through our office.
As it pertains to this review process, this license would be considered
"new" as it has been in use for only a few months.
The attached PPPL BSD-3 License complies with the Open Source Definition,
including clauses 3, 5, 6, and 9.
Anarrima (https://github.com/PrincetonUniversity/anarrima) has been made
publicly available with the PPPL BSD-3 License, and several other
PPPL-developed codes will be imminently open sourced with it.
The license steward is PPPL's Strategic Engagement and Applications
Development office (SEAD at pppl.gov).
The license name is Princeton Plasma Physics Lab BSD Variant License with
the identifier BSD-3-Clause-PPPL.
The gap filled by this additional license is PPPL's ability to assert
copyright on software authored by its staff and affiliates. When DOE-funded
software announcements are made in accordance with our government contract
at https://www.osti.gov/doecode/ the announcement requires the name and/or
link to the OSS License. Having the PPPL version of the BSD-3-Clause-PPPL
published on opensource.org will reduce confusion by enabling links to the
correct document.
It is most similar to LBNL's BSD-3 license (
https://opensource.org/license/bsd-3-clause-lbnl) with PPPL's name
substituted throughout.
The license has not been through legal review.
I am happy to address any further questions or comments regarding this
license.
Best,
Will Rarich
