THIS LICENSE DEFINES THE RIGHTS OF USE, REPRODUCTION, DISTRIBUTION, MODIFICATION, AND REDISTRIBUTION OF CERTAIN COVERED SOFTWARE (AS DEFINED BELOW) ORIGINALLY RELEASED BY THE OPEN SOURCE ELECTION TECHNOLOGY FOUNDATION (FORMERLY “THE OSDV FOUNDATION”). ANYONE WHO USES, REPRODUCES, DISTRIBUTES, MODIFIES, OR REDISTRIBUTES THE COVERED SOFTWARE, OR ANY PART THEREOF, IS BY THAT ACTION, ACCEPTING IN FULL THE TERMS CONTAINED IN THIS AGREEMENT. IF YOU DO NOT AGREE TO SUCH TERMS, YOU ARE NOT PERMITTED TO USE THE COVERED SOFTWARE.
This license was prepared based on the Mozilla Public License (“MPL”), version 2.0. For annotation of the differences between this license and MPL 2.0, please see the OSET Foundation web site at www.OSETFoundation.org/public-license.

License Grants and Conditions
Each Contributor hereby grants You a world-wide, royalty-free, non-exclusive license:
under intellectual property rights (other than patent or trademark) Licensable by such Contributor to use, reproduce, make available, modify, display, perform, distribute, and otherwise exploit its Contributions, either on an unmodified basis, with Modifications, or as part of a Larger Work; and
under Patent Claims of such Contributor to make, use, sell, offer for sale, have made, import, and otherwise transfer either its Contributions or its Contributor Version.
The licenses granted in Section 2.1 with respect to any Contribution become effective for each Contribution on the date the Contributor first distributes such Contribution.
Limitations on Grant Scope
The licenses granted in this Section 2 are the only rights granted under this License. No additional rights or licenses will be implied from the distribution or licensing of Covered Software under this License. Notwithstanding Section 2.1(b) above, no patent license is granted by a Contributor:
for any code that a Contributor has removed from Covered Software; or
for infringements caused by: (i) Your and any other third party’s modifications of Covered Software, or (ii) the combination of its Contributions with other software (except as part of its Contributor Version);
under Patent Claims infringed by Covered Software in the absence of its Contributions.
This License does not grant any rights in the trademarks, service marks, or logos of any Contributor (except as may be necessary to comply with the notice requirements in Section 3.4).
No Contributor makes additional grants as a result of Your choice to distribute the Covered Software under a subsequent version of this License (see Section 10.2) or under the terms of a Secondary License (if permitted under the terms of Section 3.3).
Each Contributor represents that the Contributor believes its Contributions are its original creation(s) or it has sufficient rights to grant the rights to its Contributions conveyed by this License.
This License is not intended to limit any rights You have under applicable copyright doctrines of fair use, fair dealing, or other equivalents.
Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted in Section 2.1.
Distribution of Source Form
All distribution of Covered Software in Source Code Form, including any Modifications that You create or to which You contribute, must be under the terms of this License. You must inform recipients that the Source Code Form of the Covered Software is governed by the terms of this License, and how they can obtain a copy of this License. You must cause any of Your Modifications to carry prominent notices stating that You changed the files. You may not attempt to alter or restrict the recipients’ rights in the Source Code Form.
Distribution of Executable Form
If You distribute Covered Software in Executable Form then:
such Covered Software must also be made available in Source Code Form, as described in Section 3.1, and You must inform recipients of the Executable Form how they can obtain a copy of such Source Code Form by reasonable means in a timely manner, at a charge no more than the cost of distribution to the recipient; and
You may distribute such Executable Form under the terms of this License, or sublicense it under different terms, provided that the license for the Executable Form does not attempt to limit or alter the recipients’ rights in the Source Code Form under this License.
Distribution of a Larger Work
You may create and distribute a Larger Work under terms of Your choice, provided that You also comply with the requirements of this License for the Covered Software. If the Larger Work is a combination of Covered Software
with a work governed by one or more Secondary Licenses, and the Covered Software is not Incompatible With Secondary Licenses, this License permits You to additionally distribute such Covered Software under the terms of such Secondary License(s), so that the recipient of the Larger Work may, at their option, further distribute the Covered Software under the terms of either this License or such Secondary License(s).
You may not remove or alter the substance of any license notices (including copyright notices, patent notices, disclaimers of warranty, or limitations of liability) contained within the Source Code Form of the Covered Software, except that You may alter any license notices to the extent required to remedy known factual inaccuracies.
Application of Additional Terms
You may choose to offer, and to charge a fee for, warranty, support, indemnity or liability obligations to one or more recipients of Covered Software. However, You may do so only on Your own behalf, and not on behalf of any Contributor. You must make it absolutely clear that any such warranty, support, indemnity, or liability obligation is offered by You alone, and You hereby agree to indemnify every Contributor for any liability incurred by such Contributor as a result of warranty, support, indemnity or liability terms You offer. You may include additional disclaimers of warranty and limitations of liability specific to any jurisdiction.
You may place additional conditions upon the rights granted in this License to the extent necessary due to statute, judicial order, regulation (including without limitation state and federal procurement regulation), national security, or public interest. Any such additional conditions must be clearly described in the notice provisions required under Section 3.4. Any alteration of the terms of this License will apply to all copies of the Covered Software distributed by You or by any downstream recipients that receive the Covered Software from You.
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 Software 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 notices required under Section 3.4. 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.
Failure to Comply
The rights granted under this License will terminate automatically if You fail to comply with any of its terms. However, if You become compliant, then the rights granted under this License from a particular Contributor are reinstated
(a) provisionally, unless and until such Contributor explicitly and finally terminates Your grants, and (b) on an ongoing basis, if such Contributor fails to notify You of the non-compliance by some reasonable means prior to 60-
days after You have come back into compliance. Moreover, Your grants from a particular Contributor are reinstated on an ongoing basis if such Contributor notifies You of the non-compliance by some reasonable means, this is the first time You have received notice of non-compliance with this License from such Contributor, and You become compliant prior to 30-days after Your receipt of the notice.
Patent Infringement Claims
If You initiate litigation against any entity by asserting a patent infringement claim (excluding declaratory judgment actions, counter-claims, and cross- claims) alleging that a Contributor Version directly or indirectly infringes any patent, then the rights granted to You by any and all Contributors for the Covered Software under Section 2.1 of this License shall terminate.
Additional Compliance Terms
Notwithstanding the foregoing in this Section 5, for purposes of this Section, if You breach Section 3.1 (Distribution of Source Form), Section 3.2 (Distribution of Executable Form), Section 3.3 (Distribution of a Larger Work), or Section 3.4 (Notices), then becoming compliant as described in Section 5.1 must also include, no later than 30 days after receipt by You of notice of such violation by a Contributor, making the Covered Software available in Source Code Form as required by this License on a publicly available computer network for a period of no less than three (3) years.
If You fail to comply with the terms of this License and do not thereafter become
compliant in accordance with Section 5.1 and, if applicable, Section 5.3, then each Contributor reserves its right, in addition to any other rights it may have in law or in equity, to bring an action seeking injunctive relief, or damages for willful copyright or patent infringement (including without limitation damages for unjust enrichment, where available under law), for all actions in violation of rights that would otherwise have been granted under the terms of this License.
End User License Agreements
In the event of termination under this Section 5, all end user license agreements
(excluding distributors and resellers), which have been validly granted by You or Your distributors under this License prior to termination shall survive termination.
Disclaimer of Warranty
Covered Software is provided under this License on an “as is” basis, without warranty of any kind, either expressed, implied, or statutory, including, without limitation, warranties that the Covered Software 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 Software is with You. Should any Covered Software prove defective in any respect, You (not any 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 Software is authorized under this License except under this disclaimer.
Limitation of Liability
Under no circumstances and under no legal theory, whether tort (including negligence), contract, or otherwise, shall any Contributor, or anyone who distributes Covered Software as permitted above, be liable to You for any direct, indirect, special, incidental, or consequential damages of any character including, without limitation, damages for lost profits, 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.
Any litigation relating to this License may be brought only in the courts of a jurisdiction where the defendant maintains its principal place of business and such litigation shall be governed by laws of that jurisdiction, without reference to its conflict-of-law provisions. Nothing in this Section shall prevent a party’s ability to bring cross-claims or counter-claims.
The Covered Software 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 Software with only those rights set forth herein.
No Sovereign Immunity
The U.S. federal government and states that use or distribute Covered Software hereby waive their sovereign immunity with respect to enforcement of the provisions of this License.
Choice of Law and Venue
If You are a government of a state of the United States, or Your use of the Covered Software is pursuant to a procurement contract with such a state government, this License shall be governed by the law of such state, excluding its conflict-of-law provisions, and the adjudication of disputes relating to this License will be subject to the exclusive jurisdiction of the state and federal courts located in such state.
If You are an agency of the United States federal government, or Your use of the Covered Software is pursuant to a procurement contract with such an agency, this License shall be governed by federal law for all purposes, and the adjudication of disputes relating to this License will be subject to the exclusive jurisdiction of the federal courts located in Washington,
You may alter the terms of this Section 9.3 for this License as described in Section 3.5.2.
This Section 9 is in lieu of, and supersedes, any other Federal Acquisition Regulation, Defense Federal Acquisition Regulation, or other clause or provision that addresses government rights in computer software under this License.
This License represents the complete agreement concerning the 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. Any law or regulation, which provides that the language of a contract shall be construed against the drafter, shall not be used to construe this License against a Contributor.
Versions of the License
The Open Source Election Technology Foundation (“OSET”) (formerly known as the Open Source Digital Voting Foundation) is the steward of this License. Except as provided in Section 11.3, no one other than the license steward has the right to modify or publish new versions of this License. Each version will be given a distinguishing version number.
Effects of New Versions
You may distribute the Covered Software under the terms of the version of the License under which You originally received the Covered Software, or under the terms of any subsequent version published by the license steward.
If You create software not governed by this License, and You want to create a new license for such software, You may create and use a modified version of this License if You rename the license and remove any references to the name of the license steward (except to note that such modified license differs from this License).
Distributing Source Code Form That is Incompatible With Secondary Licenses
If You choose to distribute Source Code Form that is Incompatible With Secondary Licenses under the terms of this version of the License, the notice described in Exhibit B of this License must be attached.
EXHIBIT A – Source Code Form License Notice
This Source Code Form is subject to the terms of the OSET Public License, v.2.1 (“OPL”). If a copy of the OPL was not distributed with this file, You can obtain one at: www.OSETFoundation.org/public-license.
If it is not possible or desirable to put the Notice in a particular file, then You may include the Notice in a location (e.g., such as a LICENSE file in a relevant directory) where a recipient would be likely to look for such a notice. You may add additional accurate notices of copyright ownership.
EXHIBIT B - “Incompatible With Secondary License” Notice
This Source Code Form is “Incompatible With Secondary Licenses”, as defined by the OSET Public License, v.2.1.
About Licensing TrustTheVote Project ElectOS Software
All OSET-supported research and development work results in open-source software. The software is available via an OSI accredited open-source license, the OSET Public License (or OSET-PL), and is distributed via our public-access source code repository. Eventually portions of this software will be housed in a special repository capable of performing license managed distribution for officially certified versions of source code intended for deployment in commercially delivered voting systems (more on this below).
A very important feature of the OSET-PL is that if you are not a government organization attempting to use ElectOS software as part of a commercial acquisition of a certified voting system that incorporates this software, or you are not a commercial vendor in the ordinary course of business of providing elections technology goods or services, then ElectOS software may be acquired pursuant to the terms and conditions of the GPL.v3 license if you prefer.
At the point the ElectOS voting system is ready for testing and certification, a new repository system will be launched, designed to provide for additional integrity assurance and protections to be reviewed by the U.S. Elections Assistance Commission for the production version of the code base. The development, experimentation and testing version of the code not intended to be integrated with production hardware will continue to be available through a less-restrictive means. All of the code, regardless of the "sandbox" where it resides will always be available public inspection on at least a "read-only" basis. More will be published about the production repository system as that point draws nearer.
The OSS licensing requirements of this narrow domain (elections jurisdictions acquiring digital technology) should not be conflated with the licensing of OSS to Federal agencies who operate under different procurement regulations that more easily support well-settled principles of broader OSS licensing.
Practically speaking, although anyone can acquire software works resulting from the R&D and education charter of the OSET Institute, or source code from the TrustTheVote Project, the typical licensee will be a State, county, or local elections jurisdiction -- either directly, or indirectly through their chosen systems integration vendor.
To be sure, our preference would have been to simply rely on a popular OSS licensing method (i.e., GPL.v3). We developed the OSET-PL after extended careful consideration of the deployment realities in local governments. We would not have taken the time (let alone money) to do so without a clear requirement to do so from Stakeholder feedback.
To learn more about the rationale for the OSET-PL, why it was necessary, and why it is based on the Mozilla Public License, please read our OSET Public License Rationale Document.
For more information we have an "FAQ" available in PDF form here: OSET-PL FAQ .pdf
The OSET-PL version 2.1 is in force as of 07.December 2015 and supersedes all prior versions. Pursuant to Section 11.2, you may distribute Covered Software under the terms of the version of the License under which you originally received the Covered Software, or under the terms of any subsequent version published by the license steward, the OSET Institute. We've made additional refinements and improvements to language and meaning to properly express intent thanks to the helpful guidance of the Open Source Initiative.
