OpenContent License (OPL)
Version 1.0, July 14, 1998.
This document outlines the principles underlying the OpenContent
(OC) movement and may be redistributed provided it remains
unaltered. For legal purposes, this document is the license
under which OpenContent is made available for use.
Terms and Conditions for Copying, Distributing, and Modifying
Items other than copying, distributing, and modifying the
Content with which this license was distributed (such as using,
etc.) are outside the scope of this license.
1. You may copy and distribute exact replicas of the OpenContent (OC)
as you receive it, in any medium, provided that you conspicuously and
appropriately publish on each copy an appropriate copyright notice and
disclaimer of warranty; keep intact all the notices that refer to this
License and to the absence of any warranty; and give any other
recipients of the OC a copy of this License along with the OC. You may
at your option charge a fee for the media and/or handling involved in
creating a unique copy of the OC for use offline, you may at your option
offer instructional support for the OC in exchange for a fee, or you may
at your option offer warranty in exchange for a fee. You may not charge
a fee for the OC itself. You may not charge a fee for the sole service of
providing access to and/or use of the OC via a network (e.g. the
Internet), whether it be via the world wide web, FTP, or any other
2. You may modify your copy or copies of the OpenContent or any portion
of it, thus forming works based on the Content, and distribute
such modifications or work under the terms of Section 1 above, provided
that you also meet all of these conditions:
a) You must cause the modified content to carry prominent notices stating
that you changed it, the exact nature and content of the changes,
and the date of any change.
b) You must cause any work that you distribute or publish, that in whole
or in part contains or is derived from the OC or any part thereof, to be
licensed as a whole at no charge to all third parties under the terms of
this License, unless otherwise permitted under applicable Fair Use law.
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the OC, and can
be reasonably considered independent and separate works in themselves,
then this License, and its terms, do not apply to those sections when
you distribute them as separate works. But when you distribute the same
sections as part of a whole which is a work based on the OC, the
distribution of the whole must be on the terms of this License, whose
permissions for other licensees extend to the entire whole, and thus to
each and every part regardless of who wrote it. Exceptions are made to
this requirement to release modified works free of charge under this
license only in compliance with Fair Use law where applicable.
3. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to copy,
distribute or modify the OC. These actions are prohibited by law if you
do not accept this License. Therefore, by distributing or translating
the OC, or by deriving works herefrom, you indicate your acceptance of
this License to do so, and all its terms and conditions for copying,
distributing or translating the OC.
4. BECAUSE THE OPENCONTENT (OC) IS LICENSED FREE OF CHARGE, THERE IS
NO WARRANTY FOR THE OC, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT
WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER
PARTIES PROVIDE THE OC "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER
EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED
WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.
THE ENTIRE RISK OF USE OF THE OC IS WITH YOU.
SHOULD THE OC PROVE FAULTY, INACCURATE, OR OTHERWISE UNACCEPTABLE
YOU ASSUME THE COST OF ALL NECESSARY REPAIR OR CORRECTION.
5. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MIRROR AND/OR
REDISTRIBUTE THE OC AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES
ARISING OUT OF THE USE OR INABILITY TO USE THE OC, EVEN IF SUCH HOLDER OR
OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
