going on right now regarding the license names and we do wish to have them be as clear and communicative as possible. I can't say where we'll come down on this in the end, but it's great to get this feedback, much of which we have not had the opportunity
to hear before. </font></div>

<div>Hi Jon --<br>
<br>
Great that Microsoft has taken the step to submit licenses to OSI. One question. Vanity licenses are a known and understood problem. Would you consider submitting these licenses with more generic names?
<br>
<br>
When we did this with CPAL it met a favorable response from the community.<br>

<p>Microsoft is pleased to submit the Microsoft Permissive License to the OSI for consideration as an OSI approved license. Microsoft believes that this license provides unique value to the open source community by delivering simplicity, brevity, and permissive
terms combined with intellectual property protection.</p>
<p>The three sections below provide the information required for the discussion portion of the approval process. We look forward to working with the OSI on this submission process and discussing this submission with the open source community.

<p></p>
<p>Section I: Which OSI licenses are similar and why won't one of those do instead?</p>
<p style="TEXT-INDENT: 0.5in">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.
</p>
<p style="TEXT-INDENT: 0.5in"> </p>
<p>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.</p>
<p style="TEXT-INDENT: -0.25in"><span style="FONT-FAMILY: Symbol"><span>·<span>
</span></span></span>Can MS-PL code be redistributed under a different license?: </p>
<p style="MARGIN-LEFT: 0.5in; TEXT-INDENT: 0.25in">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.
</p>
<p style="TEXT-INDENT: -0.25in"><span style="FONT-FAMILY: Symbol"><span>·<span>
</span></span></span>Can MS-PL code be redistributed in combination with other code that is licensed under a different license?</p>
<p style="MARGIN-LEFT: 0.5in; TEXT-INDENT: 0.25in">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.</p>
<p>Section III: The License: A copy of the license is included below and also provided as a .txt file attachment.</p>
