Microsoft is pleased to submit the Microsoft Reciprocal License to the OSI for consideration
as an OSI approved license.  This license contains the same terms as the previously
submitted Microsoft Community License, but has been renamed for greater clarity, and
resubmitted in accordance with OSI guidelines.     Microsoft believes that this license
provides unique value to the open source community by delivering simplicity, brevity,
and clearly delineated reciprocal terms.
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.

Section  I:  Which OSI licenses are similar and why won't one of those do instead?

Although one can assess similarity of license terms in numerous ways, the MS-RL has
some similarities to the Mozilla Public License (V1.1).  However, we sought to draft
a license that is simple, short, and easy-to-understand.  In particular, the Mozilla
Public License's definitions of original code, covered code, and modifications can be
difficult to apply in practice, given the many ways in which software can be distributed
and linked together.  The MS-RL provides a clear objective test of whether or not a
derivative work constitutes a modification of the original code.
Section II: Compatibilities and incompatibilities with other OSI licenses:  Source code
distribution breaks down into two areas: Relicensing of MS-RL code and redistribution
of MS-RL code with other code that is licensed under a different license.

*         Can MS-RL code be redistributed under a different license?
 No.  The license states that "If you distribute any portion of the software in source
code form, you may do so only under this license... "  This restriction is similar to
the restriction in the Mozilla Public License that states "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."  The license explicitly prohibits
relicensing of the original licensed code under a different license, in whole, in part
or as part of a different piece of software.

*         Can MS-RL code be redistributed in combination with other code that is licensed
under a different license?
As long as any files containing the original MS-RL licensed code are redistributed under
the MS-RL license, then the MS-RL  places no restrictions on combining MS-RL code with
other code that is licensed under  another license.  Any files containing any of the
MS-RL licensed code must be distributed only under the MS-RL license and not under any
other 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-RL.
Section III: The License:  A copy of the license is included below and also provided

Microsoft Reciprocal License (MS-RL)

This license governs use of the accompanying software. If you use the software, you
accept this
license. If you do not accept the license, do not use the software.

1. Definitions
The terms "reproduce," "reproduction," "derivative works," and "distribution" have the
same meaning here
as under U.S. copyright law.
A "contribution" is the original software, or any additions or changes to the software.
A "contributor" is any person that distributes its contribution under this license.
 "Licensed patents" are a contributor's patent claims that read directly on its contribution.

2. Grant of Rights
(A) Copyright Grant- Subject to the terms of this license, including the license conditions
and limitations in
section 3, each contributor grants you a non-exclusive, worldwide, royalty-free copyright
license to
reproduce its contribution, prepare derivative works of its contribution, and distribute
its contribution or any
derivative works that you create.
(B) Patent Grant- Subject to the terms of this license, including the license conditions
and limitations in
section 3, each contributor grants you a non-exclusive, worldwide, royalty-free license
under its licensed
patents to make, have made, use, sell, offer for sale, import, and/or otherwise dispose
of its contribution in
the software or derivative works of the contribution in the software.

3. Conditions and Limitations
(A) Reciprocal Grants- For any file you distribute that contains code from the software
(in source code or
binary format), you must provide recipients the source code to that file along with
a copy of this license,
which license will govern that file. You may license other files that are entirely your
own work and do not
contain code from the software under any terms you choose.
(B) No Trademark License- This license does not grant you rights to use any contributors'
name, logo, or
trademarks.
(C) If you bring a patent claim against any contributor over patents that you claim
are infringed by the
software, your patent license from such contributor to the software ends automatically.
(D) If you distribute any portion of the software, you must retain all copyright, patent,
trademark, and
attribution notices that are present in the software.
(E) If you distribute any portion of the software in source code form, you may do so
only under this license
by including a complete copy of this license with your distribution. If you distribute
any portion of the
software in compiled or object code form, you may only do so under a license that complies
with this
license.
(F) The software is licensed "as-is." You bear the risk of using it. The contributors
give no express
warranties, guarantees or conditions. You may have additional consumer rights under
your local laws which
this license cannot change. To the extent permitted under your local laws, the contributors
exclude the
implied warranties of merchantability, fitness for a particular purpose and non-infringement.
