3. Distribution Obligations.
3.1 Application of License.
The Modifications which You create or to which You contribute are governed by
the terms of this License, including without limitation Section 2.2. The Source
Code version of Covered Code may be distributed only under the terms of this
License or a future version of this License released under Section 6.1, and You
must include a copy of this License with every copy of the Source Code You
distribute. 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. However, You may include an additional
document offering the additional rights described in Section 3.5.
3.2 Availability of Source Code.
Any Modification which You create or to which You contribute must be made
available in Source Code form under the terms of this License either on the
same media as an Executable version or via an accepted Electronic Distribution
Mechanism to anyone to whom you made an Executable version available; and if
made available via Electronic Distribution Mechanism, must remain available for
at least twelve (12) months after the date it initially became available, or at
least six (6) months after a subsequent version of that particular Modification
has been made available to such recipients. You are responsible for ensuring
that the Source Code version remains available even if the Electronic
Distribution Mechanism is maintained by a third party.
3.3 Description of Modifications.
You must cause all Covered Code to which You contribute to contain a file
documenting the changes You made to create that Covered Code and the date of
any change. You must include a prominent statement that the Modification is
derived, directly or indirectly, from Original Code provided by the Initial
Developer and including the name of the Initial Developer in (a) the Source
Code, and (b) in any notice in an Executable version or related documentation
in which You describe the origin or ownership of the Covered Code.
3.4 Intellectual Property Matters
(a) Third Party Claims.
If Contributor has knowledge that a license under a third party’s
intellectual property rights is required to exercise the rights granted by such
Contributor under Sections 2.1 or 2.2, Contributor must include a text file
with the Source Code distribution titled "LEGAL" which describes
the claim and the party making the claim in sufficient detail that a recipient
will know whom to contact. If Contributor obtains such knowledge after the
Modification is made available as described in Section 3.2, Contributor shall
promptly modify the LEGAL file in all copies Contributor makes available
thereafter and shall take other steps (such as notifying appropriate mailing
lists or newsgroups) reasonably calculated to inform those who received the
Covered Code that new knowledge has been obtained.
(b) Contributor APIs.
If Contributor’s Modifications include an application programming
interface and Contributor has knowledge of patent licenses which are reasonably
necessary to implement that API, Contributor must also include this information
in the LEGAL file.
(c) Representations.
Contributor represents that, except as disclosed pursuant to Section 3.4(a)
above, Contributor believes that Contributor’s Modifications are
Contributor’s original creation(s) and/or Contributor has sufficient
rights to grant the rights conveyed by this License.
3.5 Required Notices.
You must duplicate the notice in Exhibit A in each file of the Source Code. If
it is not possible to put such notice in a particular Source Code file due to
its structure, then You must include such notice in a location (such as a
relevant directory) where a user would be likely to look for such a notice. If
You created one or more Modification(s) You may add your name as a Contributor
to the notice described in Exhibit A. You must also duplicate this License in
any documentation for the Source Code where You describe recipients’
rights or ownership rights relating to Covered Code. You may choose to offer,
and to charge a fee for, warranty, support, indemnity or liability obligations
to one or more recipients of Covered Code. However, You may do so only on Your
own behalf, and not on behalf of the Initial Developer or any Contributor. You
must make it absolutely clear than any such warranty, support, indemnity or
liability obligation is offered by You alone, and You hereby agree to indemnify
the Initial Developer and every Contributor for any liability incurred by the
Initial Developer or such Contributor as a result of warranty, support,
indemnity or liability terms You offer.
3.6 Distribution of Executable Versions.
You may distribute Covered Code in Executable form only if the requirements of
Section 3.1-3.5 have been met for that Covered Code, and if You include a
notice stating that the Source Code version of the Covered Code is available
under the terms of this License, including a description of how and where You
have fulfilled the obligations of Section 3.2. The notice must be conspicuously
included in any notice in an Executable version, related documentation or
collateral in which You describe recipients’ rights relating to the
Covered Code. You may distribute the Executable version of Covered Code or
ownership rights under a license of Your choice, which may contain terms
different from this License, provided that You are in compliance with the terms
of this License and that the license for the Executable version does not
attempt to limit or alter the recipient’s rights in the Source Code
version from the rights set forth in this License. If You distribute the
Executable version under a different license You must make it absolutely clear
that any terms which differ from this License are offered by You alone, not by
the Initial Developer, Original Developer or any Contributor. You hereby agree
to indemnify the Initial Developer, Original Developer and every Contributor
for any liability incurred by the Initial Developer, Original Developer or such
Contributor as a result of any such terms You offer.
3.7 Larger Works.
You may create a Larger Work by combining Covered Code with other code not
governed by the terms of this License and distribute the Larger Work as a
single product. In such a case, You must make sure the requirements of this
License are fulfilled for the Covered Code.
4. Inability to Comply Due to Statute or Regulation.
If it is impossible for You to comply with any of the terms of this License
with respect to some or all of the Covered Code due to statute, judicial order,
or regulation then You must: (a) comply with the terms of this License to the
maximum extent possible; and (b) describe the limitations and the code they
affect. Such description must be included in the LEGAL file described in
Section 3.4 and must be included with all distributions of the Source Code.
Except to the extent prohibited by statute or regulation, such description must
be sufficiently detailed for a recipient of ordinary skill to be able to
understand it.
5. Application of this License.
This License applies to code to which the Initial Developer has attached the
notice in Exhibit A and to related Covered Code.
6. Versions of the License.
6.1 New Versions.
Socialtext, Inc. ("Socialtext") may publish revised and/or new
versions of the License from time to time. Each version will be given a
distinguishing version number.
6.2 Effect of New Versions.
Once Covered Code has been published under a particular version of the License,
You may always continue to use it under the terms of that version. You may also
choose to use such Covered Code under the terms of any subsequent version of
the License published by Socialtext. No one other than Socialtext has the right
to modify the terms applicable to Covered Code created under this License.
6.3 Derivative Works.
If You create or use a modified version of this License (which you may only do
in order to apply it to code which is not already Covered Code governed by this
License), You must (a) rename Your license so that the phrases
"Socialtext", "CPAL" or any confusingly similar phrase
do not appear in your license (except to note that your license differs from
this License) and (b) otherwise make it clear that Your version of the license
contains terms which differ from the CPAL. (Filling in the name of the Initial
Developer, Original Developer, Original Code or Contributor in the notice
described in Exhibit A shall not of themselves be deemed to be modifications of
this License.)
7. DISCLAIMER OF WARRANTY.
COVERED CODE IS PROVIDED UNDER THIS LICENSE ON AN "AS IS" BASIS,
WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, WITHOUT
LIMITATION, WARRANTIES THAT THE COVERED CODE IS FREE OF DEFECTS, MERCHANTABLE,
FIT FOR A PARTICULAR PURPOSE OR NON-INFRINGING. THE ENTIRE RISK AS TO THE
QUALITY AND PERFORMANCE OF THE COVERED CODE IS WITH YOU. SHOULD ANY COVERED
CODE PROVE DEFECTIVE IN ANY RESPECT, YOU (NOT THE INITIAL DEVELOPER, ORIGINAL
DEVELOPER OR ANY OTHER CONTRIBUTOR) ASSUME THE COST OF ANY NECESSARY SERVICING,
REPAIR OR CORRECTION. THIS DISCLAIMER OF WARRANTY CONSTITUTES AN ESSENTIAL PART
OF THIS LICENSE. NO USE OF ANY COVERED CODE IS AUTHORIZED HEREUNDER EXCEPT
UNDER THIS DISCLAIMER.
8. TERMINATION.
8.1 This License and the rights granted hereunder will terminate automatically
if You fail to comply with terms herein and fail to cure such breach within 30
days of becoming aware of the breach. All sublicenses to the Covered Code which
are properly granted shall survive any termination of this License. Provisions
which, by their nature, must remain in effect beyond the termination of this
License shall survive.
8.2 If You initiate litigation by asserting a patent infringement claim
(excluding declatory judgment actions) against Initial Developer, Original
Developer or a Contributor (the Initial Developer, Original Developer or
Contributor against whom You file such action is referred to as
"Participant") alleging that:
(a) such Participant’s Contributor Version directly or indirectly
infringes any patent, then any and all rights granted by such Participant to
You under Sections 2.1 and/or 2.2 of this License shall, upon 60 days notice
from Participant terminate prospectively, unless if within 60 days after
receipt of notice You either: (i) agree in writing to pay Participant a
mutually agreeable reasonable royalty for Your past and future use of
Modifications made by such Participant, or (ii) withdraw Your litigation claim
with respect to the Contributor Version against such Participant. If within 60
days of notice, a reasonable royalty and payment arrangement are not mutually
agreed upon in writing by the parties or the litigation claim is not withdrawn,
the rights granted by Participant to You under Sections 2.1 and/or 2.2
automatically terminate at the expiration of the 60 day notice period specified
above.
(b) any software, hardware, or device, other than such Participant’s
Contributor Version, directly or indirectly infringes any patent, then any
rights granted to You by such Participant under Sections 2.1(b) and 2.2(b) are
revoked effective as of the date You first made, used, sold, distributed, or
had made, Modifications made by that Participant.
8.3 If You assert a patent infringement claim against Participant alleging that
such Participant’s Contributor Version directly or indirectly infringes
any patent where such claim is resolved (such as by license or settlement)
prior to the initiation of patent infringement litigation, then the reasonable
value of the licenses granted by such Participant under Sections 2.1 or 2.2
shall be taken into account in determining the amount or value of any payment
or license.
8.4 In the event of termination under Sections 8.1 or 8.2 above, all end user
license agreements (excluding distributors and resellers) which have been
validly granted by You or any distributor hereunder prior to termination shall
survive termination.
9. LIMITATION OF LIABILITY.
UNDER NO CIRCUMSTANCES AND UNDER NO LEGAL THEORY, WHETHER TORT (INCLUDING
NEGLIGENCE), CONTRACT, OR OTHERWISE, SHALL YOU, THE INITIAL DEVELOPER, ORIGINAL
DEVELOPER, ANY OTHER CONTRIBUTOR, OR ANY DISTRIBUTOR OF COVERED CODE, OR ANY
SUPPLIER OF ANY OF SUCH PARTIES, BE LIABLE TO ANY PERSON FOR ANY INDIRECT,
SPECIAL, INCIDENTAL, OR CONSEQUENTIAL DAMAGES OF ANY CHARACTER INCLUDING,
WITHOUT LIMITATION, DAMAGES FOR LOSS OF GOODWILL, WORK STOPPAGE, COMPUTER
FAILURE OR MALFUNCTION, OR ANY AND ALL OTHER COMMERCIAL DAMAGES OR LOSSES, EVEN
IF SUCH PARTY SHALL HAVE BEEN INFORMED OF THE POSSIBILITY OF SUCH DAMAGES. THIS
LIMITATION OF LIABILITY SHALL NOT APPLY TO LIABILITY FOR DEATH OR PERSONAL
INJURY RESULTING FROM SUCH PARTY’S NEGLIGENCE TO THE EXTENT APPLICABLE
LAW PROHIBITS SUCH LIMITATION. SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION OR
LIMITATION OF INCIDENTAL OR CONSEQUENTIAL DAMAGES, SO THIS EXCLUSION AND
LIMITATION MAY NOT APPLY TO YOU.
10. U.S. GOVERNMENT END USERS.
The Covered Code is a "commercial item," as that term is defined in
48 C.F.R. 2.101 (Oct. 1995), consisting of "commercial computer
software" and "commercial computer software documentation,"
as such terms are used in 48 C.F.R. 12.212 (Sept. 1995). Consistent with 48
C.F.R. 12.212 and 48 C.F.R. 227.7202-1 through 227.7202-4 (June 1995), all U.S.
Government End Users acquire Covered Code with only those rights set forth
herein.
11. MISCELLANEOUS.
This License represents the complete agreement concerning subject matter
hereof. If any provision of this License is held to be unenforceable, such
provision shall be reformed only to the extent necessary to make it
enforceable. This License shall be governed by California law provisions
(except to the extent applicable law, if any, provides otherwise), excluding
its conflict-of-law provisions. With respect to disputes in which at least one
party is a citizen of, or an entity chartered or registered to do business in
the United States of America, any litigation relating to this License shall be
subject to the jurisdiction of the Federal Courts of the Northern District of
California, with venue lying in Santa Clara County, California, with the losing
party responsible for costs, including without limitation, court costs and
reasonable attorneys’ fees and expenses. The application of the United
Nations Convention on Contracts for the International Sale of Goods is
expressly excluded. Any law or regulation which provides that the language of a
contract shall be construed against the drafter shall not apply to this
License.
12. RESPONSIBILITY FOR CLAIMS.
As between Initial Developer, Original Developer and the Contributors, each
party is responsible for claims and damages arising, directly or indirectly,
out of its utilization of rights under this License and You agree to work with
Initial Developer, Original Developer and Contributors to distribute such
responsibility on an equitable basis. Nothing herein is intended or shall be
deemed to constitute any admission of liability.
13. MULTIPLE-LICENSED CODE.
Initial Developer may designate portions of the Covered Code as Multiple-
Licensed. Multiple-Licensed means that the Initial Developer permits you to
utilize portions of the Covered Code under Your choice of the CPAL or the
alternative licenses, if any, specified by the Initial Developer in the file
described in Exhibit A.
14. ADDITIONAL TERM: ATTRIBUTION
(a) As a modest attribution to the organizer of the development of the Original
Code ("Original Developer"), in the hope that its promotional value
may help justify the time, money and effort invested in writing the Original
Code, the Original Developer may include in Exhibit B ("Attribution
Information") a requirement that each time an Executable and Source Code
or a Larger Work is launched or initially run (which includes initiating a
session), a prominent display of the Original Developer’s Attribution
Information (as defined below) must occur on the graphic user interface
employed by the end user to access such Covered Code (which may include display
on a splash screen), if any. The size of the graphic image should be consistent
with the size of the other elements of the Attribution Information. If the
access by the end user to the Executable and Source Code does not create a
graphic user interface for access to the Covered Code, this obligation shall
not apply. If the Original Code displays such Attribution Information in a
particular form (such as in the form of a splash screen, notice at login, an
"about" display, or dedicated attribution area on user interface
screens), continued use of such form for that Attribution Information is one
way of meeting this requirement for notice.
(b) Attribution information may only include a copyright notice, a brief
phrase, graphic image and a URL ("Attribution Information") and is
subject to the Attribution Limits as defined below. For these purposes,
prominent shall mean display for sufficient duration to give reasonable notice
to the user of the identity of the Original Developer and that if You include
Attribution Information or similar information for other parties, You must
ensure that the Attribution Information for the Original Developer shall be no
less prominent than such Attribution Information or similar information for the
other party. For greater certainty, the Original Developer may choose to
specify in Exhibit B below that the above attribution requirement only applies
to an Executable and Source Code resulting from the Original Code or any
Modification, but not a Larger Work. The intent is to provide for reasonably
modest attribution, therefore the Original Developer cannot require that You
display, at any time, more than the following information as Attribution
Information: (a) a copyright notice including the name of the Original
Developer; (b) a word or one phrase (not exceeding 10 words); (c) one graphic
image provided by the Original Developer; and (d) a URL (collectively, the
"Attribution Limits").
(c) If Exhibit B does not include any Attribution Information, then there are
no requirements for You to display any Attribution Information of the Original
Developer.
(d) You acknowledge that all trademarks, service marks and/or trade names
contained within the Attribution Information distributed with the Covered Code
are the exclusive property of their owners and may only be used with the
permission of their owners, or under circumstances otherwise permitted by law
or as expressly set out in this License.
15. ADDITIONAL TERM: NETWORK USE.
The term "External Deployment" means the use, distribution, or
communication of the Original Code or Modifications in any way such that the
Original Code or Modifications may be used by anyone other than You, whether
those works are distributed or communicated to those persons or made available
as an application intended for use over a network. As an express condition for
the grants of license hereunder, You must treat any External Deployment by You
of the Original Code or Modifications as a distribution under section 3.1 and
make Source Code available under Section 3.2.
