CodeIgniter License

Recently CodeIgniter changed it’s license to a relatively obscure open source license, OSL3. As I’m in the process of researching frameworks for a new project of sorts (more on that someday) and given that CI is my preferred framework I decided to research this a bit and compare the license with some other popular frameworks. In doing so we can see the additional complexity the new CI license introduces. While it may or may not be a problem for actual commercial development the sheer additional complexity is a big negative for CI, which is unfortunate as I believe it’s the best framework out there with the best community.

When comparing the licenses the additional complexity is easily apparent. The Symfony and Zend FW licenses are short and eminetely clear. The CI one is far more complex and leaves IMHO many open questions as to it’s actual usability for a commercially distributed product. Of course I can and should contact my lawyer before choosing an open source framework to build on, but again the first two options here are extremely clear (and hence less expensive to analyze).

New CodeIgniter License

Open Software License (“OSL”) v. 3.0
This Open Software License (the “License”) applies to any original work of authorship (the “Original
Work”) whose owner (the “Licensor”) has placed the following licensing notice adjacent to the
copyright notice for the Original Work:

Licensed under the Open Software License version 3.0

1) Grant of Copyright License. Licensor grants You a worldwide, royalty-free, non-exclusive,
sublicensable license, for the duration of the copyright, to do the following:
a) to reproduce the Original Work in copies, either alone or as part of a collective work;
b) to translate, adapt, alter, transform, modify, or arrange the Original Work, thereby creating
derivative works (“Derivative Works”) based upon the Original Work;
c) to distribute or communicate copies of the Original Work and Derivative Works to the public, with
the proviso that copies of Original Work or Derivative Works that You distribute or communicate
shall be licensed under this Open Software License;
d) to perform the Original Work publicly; and
e) to display the Original Work publicly.

2) Grant of Patent License. Licensor grants You a worldwide, royalty-free, non-exclusive,
sublicensable license, under patent claims owned or controlled by the Licensor that are embodied in
the Original Work as furnished by the Licensor, for the duration of the patents, to make, use, sell,
offer for sale, have made, and import the Original Work and Derivative Works.

3) Grant of Source Code License. The term “Source Code” means the preferred form of the Original
Work for making modifications to it and all available documentation describing how to modify the
Original Work. Licensor agrees to provide a machine-readable copy of the Source Code of the Original
Work along with each copy of the Original Work that Licensor distributes. Licensor reserves the
right to satisfy this obligation by placing a machine-readable copy of the Source Code in an
information repository reasonably calculated to permit inexpensive and convenient access by You for
as long as Licensor continues to distribute the Original Work.

4) Exclusions From License Grant. Neither the names of Licensor, nor the names of any contributors
to the Original Work, nor any of their trademarks or service marks, may be used to endorse or
promote products derived from this Original Work without express prior permission of the Licensor.
Except as expressly stated herein, nothing in this License grants any license to Licensor’s
trademarks, copyrights, patents, trade secrets or any other intellectual property. No patent license
is granted to make, use, sell, offer for sale, have made, or import embodiments of any patent claims
other than the licensed claims defined in Section 2. No license is granted to the trademarks of
Licensor even if such marks are included in the Original Work. Nothing in this License shall be
interpreted to prohibit Licensor from licensing under terms different from this License any Original
Work that Licensor otherwise would have a right to license.

5) External Deployment. The term “External Deployment” means the use, distribution, or communication
of the Original Work or Derivative Works in any way such that the Original Work or Derivative Works
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
Work or a Derivative Work as a distribution under section 1(c).

6) Attribution Rights. You must retain, in the Source Code of any Derivative Works that You create,
all copyright, patent, or trademark notices from the Source Code of the Original Work, as well as
any notices of licensing and any descriptive text identified therein as an “Attribution Notice.” You
must cause the Source Code for any Derivative Works that You create to carry a prominent Attribution
Notice reasonably calculated to inform recipients that You have modified the Original Work.

7) Warranty of Provenance and Disclaimer of Warranty. Licensor warrants that the copyright in and to
the Original Work and the patent rights granted herein by Licensor are owned by the Licensor or are
sublicensed to You under the terms of this License with the permission of the contributor(s) of
those copyrights and patent rights. Except as expressly stated in the immediately preceding
sentence, the Original Work is provided under this License on an “AS IS” BASIS and WITHOUT WARRANTY,
either express or implied, including, without limitation, the warranties of non-infringement,
merchantability or fitness for a particular purpose. THE ENTIRE RISK AS TO THE QUALITY OF THE
ORIGINAL WORK IS WITH YOU. This DISCLAIMER OF WARRANTY constitutes an essential part of this
License. No license to the Original Work is granted by this License except under this disclaimer.

8) Limitation of Liability. Under no circumstances and under no legal theory, whether in tort
(including negligence), contract, or otherwise, shall the Licensor be liable to anyone for any
indirect, special, incidental, or consequential damages of any character arising as a result of this
License or the use of the Original Work including, without limitation, damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all other commercial damages or losses.
This limitation of liability shall not apply to the extent applicable law prohibits such limitation.

9) Acceptance and Termination. If, at any time, You expressly assented to this License, that assent
indicates your clear and irrevocable acceptance of this License and all of its terms and conditions.
If You distribute or communicate copies of the Original Work or a Derivative Work, You must make a
reasonable effort under the circumstances to obtain the express assent of recipients to the terms of
this License. This License conditions your rights to undertake the activities listed in Section 1,
including your right to create Derivative Works based upon the Original Work, and doing so without
honoring these terms and conditions is prohibited by copyright law and international treaty. Nothing
in this License is intended to affect copyright exceptions and limitations (including “fair use” or
“fair dealing”). This License shall terminate immediately and You may no longer exercise any of the
rights granted to You by this License upon your failure to honor the conditions in Section 1(c).

10) Termination for Patent Action. This License shall terminate automatically and You may no longer
exercise any of the rights granted to You by this License as of the date You commence an action,
including a cross-claim or counterclaim, against Licensor or any licensee alleging that the Original
Work infringes a patent. This termination provision shall not apply for an action alleging patent
infringement by combinations of the Original Work with other software or hardware.

11) Jurisdiction, Venue and Governing Law. Any action or suit relating to this License may be
brought only in the courts of a jurisdiction wherein the Licensor resides or in which Licensor
conducts its primary business, and under the laws of that jurisdiction excluding its conflict-of-law
provisions. The application of the United Nations Convention on Contracts for the International Sale
of Goods is expressly excluded. Any use of the Original Work outside the scope of this License or
after its termination shall be subject to the requirements and penalties of copyright or patent law
in the appropriate jurisdiction. This section shall survive the termination of this License.

12) Attorneys’ Fees. In any action to enforce the terms of this License or seeking damages relating
thereto, the prevailing party shall be entitled to recover its costs and expenses, including,
without limitation, reasonable attorneys’ fees and costs incurred in connection with such action,
including any appeal of such action. This section shall survive the termination of this License.

13) Miscellaneous. 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.

14) Definition of “You” in This License. “You” throughout this License, whether in upper or lower
case, means an individual or a legal entity exercising rights under, and complying with all of the
terms of, this License. For legal entities, “You” includes any entity that controls, is controlled
by, or is under common control with you. For purposes of this definition, “control” means (i) the
power, direct or indirect, to cause the direction or management of such entity, whether by contract
or otherwise, or (ii) ownership of fifty percent (50%) or more of the outstanding shares, or (iii)
beneficial ownership of such entity.

15) Right to Use. You may use the Original Work in all ways not otherwise restricted or conditioned
by this License or by law, and Licensor promises not to interfere with or be responsible for such
uses by You.

16) Modification of This License. This License is Copyright © 2005 Lawrence Rosen. Permission is
granted to copy, distribute, or communicate this License without modification. Nothing in this
License permits You to modify this License as applied to the Original Work or to Derivative Works.
However, You may modify the text of this License and copy, distribute or communicate your modified
version (the “Modified License”) and apply it to other original works of authorship subject to the
following conditions: (i) You may not indicate in any way that your Modified License is the “Open
Software License” or “OSL” and you may not use those names in the name of your Modified License;
(ii) You must replace the notice specified in the first paragraph above with the notice “Licensed
under ” or with a notice of your own that is not confusingly similar
to the notice in this License; and (iii) You may not claim that your original works are open source
software unless your Modified License has been approved by Open Source Initiative (OSI) and You
comply with its license review and certification process.
