<div class=Section1>
<p class=MsoNormal>Microsoft is pleased to submit the Microsoft Public License
to the OSI for consideration as an OSI approved license. This license
contains the same terms as the previously submitted Microsoft Permissive
License, but has been renamed for greater clarity, and resubmitted in
accordance with OSI guidelines. <span style='color:#1F497D'> </span>Microsoft
believes that this license provides unique value to the open source community
by delivering simplicity, brevity, and permissive reuse terms combined with
intellectual property protection.<o:p></o:p></p>
<p class=MsoNormal>The three sections below provide the information required
for the discussion portion of the approval process. We look forward to
continuing to work with the OSI and the open source community on this
submission process. <o:p></o:p></p>
<p class=MsoNormal style='line-height:normal'>Jon Rosenberg<o:p></o:p></p>
<p class=MsoNormal style='line-height:normal'>Director, Source Program<o:p></o:p></p>
<p class=MsoNormal style='line-height:normal'>Microsoft Corporation<o:p></o:p></p>
<p class=MsoNormal style='line-height:normal'><o:p> </o:p></p>
<p class=MsoNormal style='line-height:normal'>----------------------------------<o:p></o:p></p>
<p class=MsoNormal> <o:p></o:p></p>
<p class=MsoNormal>Section I: Which OSI licenses are similar and
why won’t one of those do instead?<o:p></o:p></p>
<p class=MsoNormal style='text-indent:.5in'>Although one can assess similarity
of license terms in numerous ways, the MS-PL has similarities to terms in both
the New BSD license and Apache 2.0 license. However, the new BSD license
does not contain an explicit patent grant and only implicitly refers to
trademark issues. In addition, we sought to create a license that is
simple, short, and easy-to-understand. <o:p></o:p></p>
<p class=MsoNormal style='text-indent:.5in'><o:p> </o:p></p>
<p class=MsoNormal>Section II: Compatibilities and incompatibilities with other
OSI licenses: Source code distribution breaks down into two areas:
Relicensing of MS-PL code and redistribution of MS-PL code with other code that
is licensed under a different license.<o:p></o:p></p>
<p class=MsoListParagraph style='text-indent:-.25in;mso-list:l0 level1 lfo2'><![if !supportLists]><span
style='font-family:Symbol'><span style='mso-list:Ignore'>·<span
style='font:7.0pt "Times New Roman"'>
</span></span></span><![endif]>Can MS-PL code be redistributed under a
different license?: <o:p></o:p></p>
<p class=MsoNormal style='margin-left:.5in;text-indent:.25in'>No. The
license states that “<i>If you distribute any portion of the software in
source code form, you may do so only under this license…” </i>This
restriction is similar to the restriction in the Mozilla Public License that
states “<i>You may not offer or impose any terms on any Source Code
version that alters or restricts the applicable version of this License or the
recipients' rights hereunder.” </i>The MS-PL license explicitly
prohibits relicensing of the original licensed code under a different license,
regardless of whether the original code is redistributed in whole, in part or
as part of a different piece of software. <o:p></o:p></p>
<p class=MsoListParagraph style='text-indent:-.25in;mso-list:l0 level1 lfo2'><![if !supportLists]><span
style='font-family:Symbol'><span style='mso-list:Ignore'>·<span
style='font:7.0pt "Times New Roman"'>
</span></span></span><![endif]>Can MS-PL code be redistributed in combination
with other code that is licensed under a different license?<o:p></o:p></p>
<p class=MsoNormal style='margin-left:.5in;text-indent:.25in'>As long as the original
MS-PL licensed code is redistributed under the MS-PL license, then the
MS-PL places no restrictions on combining MS-PL code with other code that
is licensed under another license. Licenses that prohibit the
distribution of code under any terms other than the terms of that license will
not be compatible with the MS-PL.<o:p></o:p></p>
<p class=MsoNormal>Section III: The License: A copy of the license is included
below and also provided as a .txt file attachment.<o:p></o:p></p>
