List of suggestions:

We collected the suggestions from the License Review Mailing List as follows:


From: Carlo Piana <carlo at piana.eu>


I have one observation and one criticism.

The observation is that this looks like a couple of licenses like the BSD+patents. While arguably the text is more streamlined and modern, building on the experience in licensing that we have accrued since the BSD times, I wonder if there is such desperate need for yet another license. Except perhaps one in Chinese.

 

The criticism is founded on a long debated issue about whether multi-language licenses are a good idea. As you know, GNU GPL family decided that the only ever authoritative version is the English one, and I tend to agree with the rationale underneath. It is tremendously difficult to exactly match the same meaning across multiple languages, and my experience in dissecting legal instruments of the EU -- limiting to those few languages I am reasonably confident perusing -- is that it is very difficult to find a single meaning. Often one should find it comparing different versions and with the help of the recitals, and yet it is very difficult to reach a final point.

 

Moreover, you state in your introduction that the rule is (roughly) "either is normative". But that rule is nowhere expressed in the license itself. I am afraid this would then be totally left to the local court, in case. Yet, a license lives not only in court, but also in the current interpretation of those using it, who would not have the benefit of a third party picking up one version or the other.

 

Frankly, I see little merit in creating confusion by using two languages on equal footing. On the other hand, the fact that the license is non-copyleft reduces the concerns on possible negative consequences.

 

I wonder if those concerns have also been tackled in your legal analysis, and what the answer were, in case.

 

I totally love the name of the license.


From: Josh Berkus <josh at berkus.org>


I think Carlo was arguing that this license should state that the Chinese version is authoritative.  Certainly that would make sense to me.

 


From: Carlo <carlo at piana.eu>


Thanks Josh for spotting the point. Pretty much so. **One** version should be authoritative, IMHO. Which one, that's up to the author of the license to decide.

 

Suppose one contributor picks the English and another, for an unrelated project, the Chinese, and the two differ substantially due to a glitch in the translation. And a third party combines them. It's a minor hiccup here, as it's no copyleft, yet it's unnecessary added entropy. Which one applies? You would have two inbound and most of all two outbound

licenses in a superstate, with the same name and different legal consequences.

 

Again, not a big issue, rather a matter of elegance and "ecology".

 


From: Simon Phipps <webmink at opensource.org>


Please collect all the suggestions the list offer and then make a revised submission with a new version number that includes all the changes you intend to make, with an explanation of each change in the submission email (ideally with citations!). That way we have a single email to refer to in the final approval process.

 


From: Pamela Chestek <pamela at chesteklegal.com>


Would it be possible to make one version authoritative is some countries and the other authoritative in the rest of the world? You could says something like "the Chinese version is the official version in China, Hong Kong, etc. and the English version is the official version in the other countries of the world." If you said that the Chinese version was authoritative everywhere, and then litigate the license in the US, the Chinese version will need to be translated to English. You might then end up with a /different/ translation than the version written in English.

 

But you would want it very clear how it was divided. I would not say something like "Chinese-speaking countries" because then you get into arguments about what that means - is the United States a Chinese-speaking country because it has a sizable Chinese-speaking population? (We have no official language in the United States.)

 

Just suggesting it - does this create problems I'm not seeing?

 


From: Simon Phipps <simon at webmink.com>


Wouldn't the copyright holder's preference be the best selection? Given the two versions are essentially equivalent it doesn't matter which is selected as long as one is.

 

So maybe change the usage instructions to include a statement of which language is normative, then change the license text to state Chinese is normative unless otherwise specified in the copyright statement in the source code, so there's a default.

 


From: Pamela Chestek <pamela at chesteklegal.com>


Hmm, except that it gets sticky where each individual contributor to the same project chooses differently. That would be impossible to sort out in a lawsuit.

 

So I'm back to just picking Chinese as the controlling language.

 

This demonstrates why it's so hard to write a good license and why they can get very lengthy.

 


From: Josh Berkus <josh at berkus.org>


Do we have someone in the OSI who can review the Chinese language license?

 


From: Simon Phipps <webmink at opensource.org>


Our process requires that a notarised English translation is provided for review. In this case certification that the English version is legally equivalent would be sufficient, which we can probably assume from the status of the submitter.

 

Note that making a single version normative (if that is what the submitter chooses to do) merely indicates that where there is disputed interpretation during litigation of otherwise equivalent texts, the normative version is used by the court. It should not affect our deliberations about the overall license if both versions are certified equivalent.

 

 

Modification (compared to Mulan PSL v1):

The main concern was, we provide both Chinese version and English version of Mulan PSL v1, but what if there is disputed interpretation between both versions? To solve this problem, we add a statement in the license terms, stating that while there is any conflict between the Chinese version and the English version, the Chinese version prevails. We highly appreciate the suggestions from Carlo Piana, Josh Berkus, Simon Phipps and Pamela Chestek!

 

6。语言

     “本许可证”以中英文双语表述，中英文版本具有同等法律效力。如果中英文版本存在任何冲突不一致，以中文版为准。

6. Language

This license is written in both Chinese and English, and the Chinese version and English version shall have the same legal effect. In the case of divergence between the Chinese and English versions, the Chinese version shall prevail.

 

Rationale:

1. Mulan PSL v2 is expressed in both Chinese and English, which have the same legal effect. It is convenient for open source participants to read and use. 

2. In order to solve the existing litigation problems, Mulan PSL v2 clarifies the authorization of copyright, patent and trademark, and provides better legal protection. 

3. For the sake of simplicity and  <javascript:;> understandability, Mulan PSL v2 was revised jointly by technical experts and legal experts to simplify the terms and optimize the expression as much as possible on the premise of clarifying the behavior constraints of both parties in the License. Mulan PSL v2 is easy for users to follow.

 

Distinguish (from other OSI-approved permissive licenses):

Mulan PSL v2 differs from BSD 3-clause License and Apache License V2.0 in terms of statement obligation, copyright license, patent license and patent retaliation.

1. Statement obligation. Mulan PSL v2 only requires that the licensed software to be distributed with a copy of this License and copyright, patent, trademark and disclaimer statements in the software.

2. Copyright license. Original licensor, subsequent contributor, and Affiliates of those licensors provide the Copyright license.

3. Patent license. Original licensor, subsequent contributor, and Affiliates of those licensors provide the patent license.

4. Patent retaliation: If a user or its Affiliates directly or indirectly (including through an agent, patent licensee or assignee) institute patent litigation (including a cross claim or counterclaim in a litigation) or other patent enforcement activities against any individual or entity by alleging that the Software or any Contribution in it infringes patents, then any patent license granted to the user or its Affiliates under this License for the Software shall terminate as of the date such litigation or activity is filed or taken.

Legal Review:

Mulan PSL v2 was drafted by software experts and lawyers from colleges, research institutions,  <javascript:;> enterprises and open source communities. It has been reviewed by lawyers specialized in the field of intellectual property and open source software.

Both the Chinese and English versions of Mulan PSL v2 have the same legal effect. Users can select the appropriate version in their jurisdiction. In the event of conflicts between the Chinese version and English version, the Chinese version shall prevail. Mulan PSL v2 meets OSI’s definition of “Open Source” of OSI and OSI’s requirements. The rationale of the license is to create a license with easy compliance, better compatibility, comprehensive patent protection, and Chinese (not just English) friendly.
