<br>
It has been over a year since the last discussion on this proposal; I would like to revive it again in view of the following:<br>
<br>
1. I have gotten some feedback from the FSF on the license. At the time of initial submission of the license, several on the list suggested that, given the special purpose of this license -- to provide a version of the BSD license that was both GPLv2 compatible
and included an express patent license, I should get confirmation from the FSF that it is indeed GPLv2 compatible. I have heard from the FSF and they have confirmed the present draft [appended and discussed below] is GPLv2 compatible.<br>
<br>
2. I have also gotten feedback from others on the last draft (on-list, and privately), as well as from the FSF, which has resulted in me reconsidering the last draft and tightening up and/or altering the text somewhat (not to change the substance, just to
change ambiguities or other drafting issues). So the latest version (reproduced below, as well as appended in color-coded format to show the origin of the text) is in this e-mail.<br>
<br>
A few drafting notes on this version:<br>
<br>
A. There are two provisions in this draft that are in square brackets ([]). Those represent provisions that I have added in response to the comments of others on this list, but which I haven't yet decided should be in the final version. The first provision
(that the licensed patent claims are those "already acquired or hereafter acquired") comes from GPLv3 -- but is not in any of the licenses (BSD, Apache, Eclipse) from which my license is derived. That provision is intended to make explicit that the license
is intended to cover patents acquired by the licensor after the grant has been made. I think that that is inherent in the grant language of Apache and Eclipse (and the Apache FAQs say it is explicitly), but the language does have the benefit of making it
explicit and part of the license text itself. The second provision is an explicit disclaimer of all other licenses beyond those expressly granted. That language comes from Eclipse, with modification. I'm now of the mind to keep in the bracketed provisions,
given that I think being express/explicit is better, even if there is an argument that these provisions are somewhat unnecessary given the unbracketed language already covers the concepts. I'll leave these provisions open for additional comment by anyone
who wants to convince me there is a good reason to leave them out.<br>
<br>
B. The patent license grant is on behalf of "copyright holders and contributors." I have used that language as a result of its existing use in the disclaimer section of 2-clause BSD, which I interpret to be intended to cover those who make copyrightable contributions
as well as those who might make contributions not subject to copyright (an issue discussed in some depth in separate threads about military and/or government open source licensing, particularly those not subject to US copyright rights). In order to make that
distinction more clear, the patent clause now has an embedded definition of "Contribution(s)" which intended to now capture both types of contributions -- copyrightable and non-copyrightable. Although I tend to disfavor embedded definitions in a license of
this type (since BSD is free of them), this was one definition that seemed to be needed as a point of clarity.<br>
<br>
Further comments are welcome. Now that the GPLv2 compatibility issue is resolved, I'll leave this one open for additional comments from the member list for a bit, in case anyone sees further drafting improvements they'd like to suggest -- or express objections
as to why the license itself should not be approved. I will then indicate that the text is finalized and ask for Board approval to add to the OSI list.<br>
