Including the BSD-3 style license in releases wouldn't be a problem, as it's compatible with Apache License 2. As there are substantial changes, I believe PPMC would prefer to put the ASF header on top of the file (ie. 2 headers) [72 hours lazy consensus if there are no concerns].

HI, > In addition, Justin stated that converting the code from one program language > to another one should **NOT** be considered as a major modification. INAL but my understanding is that translation from one language to another is considered a fairly trivial task and may not be novel enough for a copyright to apply and it would not considered an original work. > So it seems more appropriate to remove the ASF header and just keep the Numpy > license header and claim it at the top level LICENSE, or do we need to vote > on the two options as Bob stated below, thanks! I think the safest think to do would be to leave the original header on and remove the ASF one.Version control will show what lines have been modified if anyone is stressed in the history.

RE: [DISCUSS] When to add Apache Headers to Third Party Code [WAS] Re: [MENTORS] PPMC case-by-case decision for major modifications of third-party work guidance
Thanks a lot for your valuable input Bob, John, Justin, Leonard. As it’s still not finalized on how to handle such dual license issue from the discussion. In addition, Justin stated that converting the code from one program language to another one should **NOT** be considered as a major modification.

Here is Justin's email that request the Apache Headers removed [1] - file copyright NumPy Developers [6] this file look to incorrectly have an ASF header on it 6. ./src/operator/numpy/np_einsum_path_op-inl.h We want to make the choice that will be most sustainable for the project and most correct for the situation. Based on the emails I linked in the prior email it does seem like the cases where dual headers are appropriate is when there are Major Modifications. In the case of np_einsum_path_op-inl.h The file is derived from the implementation in Numpy [2]. If the implementation in Numpy changes will this file change? If so then the community will be tasked with continuing to re-port the changes over that is always based on Numpy so it may be more appropriate to just keep the Numpy license. Will MXNet likely evolve this file in a way that it's no longer resembles the Numpy implementation (Major Modification)? If so it may be better to keep the Apache Header as going forward the file will represent the work of the MXNet community not that of Numpy. Hopefully the above helps clarify my perspective on how to determine case by case. I don't see the dual license state as the simpler case in all situations. I don't believe you would have to get the original committer to relicense the file to you in order to remove the additional license. I believe the PPMC has all the authority it needs to change the file. I'd be interested to hear if this is a position that the rest of the Mentors/Incubator agree with. I know Hen has been involved in some of the conversations in support of dual licenses. Has this ever required escalation to an actual Lawyer in Legal?

Re: [DISCUSS] When to add Apache Headers to Third Party Code [WAS] Re: [MENTORS] PPMC case-by-case decision for major modifications of third-party work guidance
For clarity the "additional license" in this case is the Apache License Header that a contributor added above the numpy license. I agree that the original license should remain if the file is considered derived in anyway. The podling was asking if they had authority to make the change to remove the Apache License or if they needed to reach out to the original contributor to re-license the code. I believe they have that authority with or without the contributor's permission. - Bob On 6/15/2020 7:39 AM, Justin Mclean wrote: > HI, > >> * If there’s no any different opinion or objection, keep either origin >> Numpy license or ASF license but not dual, which depends on how MXNet’s >> source file evolves when the origin Numpy files changes? > IMO only if there are significant changes to the file, if in doubt I’d keep > the original license. > >> And the PPMC has all the authority to change the file like removing the >> additional license if needed. > I would say they don’t unless the 3rd party agrees or the overwhelming > majority of the code is no longer under the original license. > > Thanks, > Justin > - > To unsubscribe, e-mail: general-unsubscr...@incubator.apache.org > For additional commands, e-mail: general-h...@incubator.apache.org > signature.asc Description: OpenPGP digital signature

We would only change the license from the NumPy license to ALv2 if an SGA or ICLA is received from all contributors historically on this file. No matter how drastic of modifications the MxNet community makes to it, it would always be NumPy licensed; so if you did want to avoid including the license in your releases you would either need to rely on the file as an external dependency or completely reimplement the functionality not deriving it from this file. Whether or not the MxNet community imports upstream changes or not is up to them, but either way you have a derived work here.

RE: [DISCUSS] When to add Apache Headers to Third Party Code [WAS] Re: [MENTORS] PPMC case-by-case decision for major modifications of third-party work guidance
Hi Bob, Leonard, Thanks for the elaboration/guideline on the dual license issue. May I have the conclusion as below based on Bob’s direction/suggestion: * If there’s no any different opinion or objection, keep either origin Numpy license or ASF license but not dual, which depends on how MXNet’s source file evolves when the origin Numpy files changes? And the PPMC has all the authority to change the file like removing the additional license if needed. Please correct me if I mis-understand anything, and help to determine the best appropriate way to handle such case. Thanks!

If so then the community will be tasked with continuing to re-port the changes over that is always based on Numpy so it may be more appropriate to just keep the Numpy license.

Reading through the threads you referenced, there does not seem to be a strong consensus in the ASF about how to handle this situation. For example, quoting Roman Shaposhnik [2] in support of just putting 2 License Headers for simplicity: Hm. This is tricky, now that I re-read the language of the ASF license header I'm not sure anymore. I *think* the language there should allow you to slap said header on a compatible license code.

I *think* (but I'd love for old-timers to chime in and correct me) that #3-5 were written from though-shall-not-fork-communities perspective. Can we follow this approach (keep 2 License headers) for simplicity (assuming removal of ASF header will require extra steps)? With respect to einsumfunc.py [5] vs np_einsum_op.cc [6] if this is in fact a port where the behavior was copied/derived directly from numpy I could see that as supporting Justin's case that the Apache header should be removed.
