+# Hule Grant and Contributor License Agreement

+

+> This agreement is based on the Harmony Combined Contributor Agreement

+> Version 1.0 licensed under a [Creative Commons Attribution 3.0 Unported License](http://creativecommons.org/licenses/by/3.0/).

+

+Thank you for your interest in contributing to Hule ("We" or "Us"). In order

+to clarify the intellectual property license granted with Contributions from any

+person or entity, We must have a Contributor License Agreement ("CLA") on file

+that has been signed, accepted or otherwise agreed to by each contributor,

+indicating agreement to the license terms below. This license is for your

+protection as a contributor as well as the protection of the Us and our users;

+it does not change your rights to use your own Contributions for any other

+purpose.

+

+## 1. Definitions

+

+"You" (Individual) means the individual who Submits a Contribution to Us.

+

+"You" (Entity) means any Legal Entity on behalf of whom a Contribution has been

+received by Us. "Legal Entity" means an entity which is not a natural person.

+"Affiliates" means other Legal Entities that control, are controlled by, or

+under common control with that Legal Entity. For the purposes of this

+definition, "control" means (i) the power, direct or indirect, to cause the

+direction or management of such Legal Entity, whether by contract or otherwise,

+(ii) ownership of fifty percent (50%) or more of the outstanding shares or

+securities which vote to elect the management or other persons who direct such

+Legal Entity or (iii) beneficial ownership of such entity.

+

+"Contribution" means any work of authorship that is Submitted by You to Us in

+which You own or assert ownership of the Copyright.

+

+"Copyright" means all rights protecting works of authorship owned or controlled

+by You [or Your Affiliates], including copyright, moral and neighboring rights,

+as appropriate, for the full term of their existence including any extensions by

+You.

+

+"Material" means the work of authorship which is made available by Us to third

+parties. When this Agreement covers more than one software project, the Material

+means the work of authorship to which the Contribution was Submitted. After You

+Submit the Contribution, it may be included in the Material.

+

+"Submit" means any form of electronic, verbal, or written communication sent to

+Us or our representatives, including but not limited to electronic mailing

+lists, source code control systems, and issue tracking systems that are managed

+by, or on behalf of, Us for the purpose of discussing and improving the

+Material, but excluding communication that is conspicuously marked or otherwise

+designated in writing by You as "Not a Contribution."

+

+"Submission Date" means the date on which You Submit a Contribution to Us.

+

+"Effective Date" means the date You execute this Agreement or the date You first

+Submit a Contribution to Us, whichever is earlier.

+

+"Media" means any portion of a Contribution which is not software.

+

+## 2. Grant of Rights

+

+### 2.1 Copyright License

+

+(a) You retain ownership of the Copyright in Your Contribution and have the same

+rights to use or license the Contribution which You would have had without

+entering into the Agreement.

+

+(b) To the maximum extent permitted by the relevant law, You grant to Us a

+perpetual, worldwide, non-exclusive, transferable, royalty-free, irrevocable

+license under the Copyright covering the Contribution, with the right to

+sublicense such rights through multiple tiers of sublicensees, to reproduce,

+modify, display, perform and distribute the Contribution as part of the

+Material; provided that this license is conditioned upon compliance with Section

+2.3.

+

+### 2.1 Copyright Assignment

+

+(a) At the time the Contribution is Submitted, You assign to Us all right,

+title, and interest worldwide in all Copyright covering the Contribution;

+provided that this transfer is conditioned upon compliance with Section 2.3.

+

+(b) To the extent that any of the rights in Section 2.1(a) cannot be assigned by

+You to Us, You grant to Us a perpetual, worldwide, exclusive, royalty-free,

+transferable, irrevocable license under such non-assigned rights, with rights to

+sublicense through multiple tiers of sublicensees, to practice such non-assigned

+rights, including, but not limited to, the right to reproduce, modify, display,

+perform and distribute the Contribution; provided that this license is

+conditioned upon compliance with Section 2.3.

+

+(c) To the extent that any of the rights in Section 2.1(a) can neither be

+assigned nor licensed by You to Us, You irrevocably waive and agree never to

+assert such rights against Us, any of our successors in interest, or any of our

+licensees, either direct or indirect; provided that this agreement not to assert

+is conditioned upon compliance with Section 2.3.

+

+(d) Upon such transfer of rights to Us, to the maximum extent possible, We

+immediately grant to You a perpetual, worldwide, non-exclusive, royalty-free,

+transferable, irrevocable license under such rights covering the Contribution,

+with rights to sublicense through multiple tiers of sublicensees, to reproduce,

+modify, display, perform, and distribute the Contribution. The intention of the

+parties is that this license will be as broad as possible and to provide You

+with rights as similar as possible to the owner of the rights that You

+transferred. This license back is limited to the Contribution and does not

+provide any rights to the Material.

+

+### 2.2 Patent License

+

+For patent claims including, without limitation, method, process, and apparatus

+claims which You [or Your Affiliates] own, control or have the right to grant,

+now or in the future, You grant to Us a perpetual, worldwide, non-exclusive,

+transferable, royalty-free, irrevocable patent license, with the right to

+sublicense these rights to multiple tiers of sublicensees, to make, have made,

+use, sell, offer for sale, import and otherwise transfer the Contribution and

+the Contribution in combination with the Material (and portions of such

+combination). This license is granted only to the extent that the exercise of

+the licensed rights infringes such patent claims; and provided that this license

+is conditioned upon compliance with Section 2.3.

+

+### 2.3 Outbound License

+

+Based on the grant of rights in Sections 2.1 and 2.2, if We include Your

+Contribution in a Material, We may license the Contribution under any license,

+including copyleft, permissive, commercial, or proprietary licenses. As a

+condition on the exercise of this right, We agree to also license the

+Contribution under the terms of the license or licenses which We are using for

+the Material on the Submission Date.

+

+### 2.4 Moral Rights

+

+If moral rights apply to the Contribution, to the maximum extent permitted by

+law, You waive and agree not to assert such moral rights against Us or our

+successors in interest, or any of our licensees, either direct or indirect.

+

+### 2.5 Our Rights

+

+You acknowledge that We are not obligated to use Your Contribution as part of

+the Material and may decide to include any Contribution We consider appropriate.

+

+### 2.6 Reservation of Rights

+

+Any rights not expressly [assigned or] licensed under this section are expressly

+reserved by You.

+

+## 3. Agreement

+

+You confirm that:

+

+(a) You have the legal authority to enter into this Agreement.

+

+(b) You [or Your Affiliates] own the Copyright and patent claims covering the

+Contribution which are required to grant the rights under Section 2.

+

+(c) (Individual) The grant of rights under Section 2 does not violate any grant

+of rights which You have made to third parties, including Your employer. If You

+are an employee, You have had Your employer approve this Agreement or sign the

+Entity version of this document. If You are less than eighteen years old, please

+have Your parents or guardian sign the Agreement.

+

+(c) (Entity) The grant of rights under Section 2 does not violate any grant of

+rights which You or Your Affiliates have made to third parties.

+

+## 4. Disclaimer

+

+EXCEPT FOR THE EXPRESS WARRANTIES IN SECTION 3, THE CONTRIBUTION IS PROVIDED "AS

+IS". MORE PARTICULARLY, ALL EXPRESS OR IMPLIED WARRANTIES INCLUDING, WITHOUT

+LIMITATION, ANY IMPLIED WARRANTY OF MERCHANTABILITY, FITNESS FOR A PARTICULAR

+PURPOSE AND NON-INFRINGEMENT ARE EXPRESSLY DISCLAIMED BY YOU TO US [AND BY US TO

+YOU]. TO THE EXTENT THAT ANY SUCH WARRANTIES CANNOT BE DISCLAIMED, SUCH WARRANTY

+IS LIMITED IN DURATION TO THE MINIMUM PERIOD PERMITTED BY LAW.

+

+## 5. Consequential Damage Waiver

+

+TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT WILL YOU [OR US]

+BE LIABLE FOR ANY LOSS OF PROFITS, LOSS OF ANTICIPATED SAVINGS, LOSS OF DATA,

+INDIRECT, SPECIAL, INCIDENTAL, CONSEQUENTIAL AND EXEMPLARY DAMAGES ARISING OUT

+OF THIS AGREEMENT REGARDLESS OF THE LEGAL OR EQUITABLE THEORY (CONTRACT, TORT OR

+OTHERWISE) UPON WHICH THE CLAIM IS BASED.

+

+## 6. Miscellaneous

+

+6.1 This Agreement sets out the entire agreement between You and Us for Your

+Contributions to Us and overrides all other agreements or understandings.

+

+6.2 If You or We assign the rights or obligations received through this

+Agreement to a third party, as a condition of the assignment, that third party

+must agree in writing to abide by all the rights and obligations in the

+Agreement.

+

+6.3 The failure of either party to require performance by the other party of any

+provision of this Agreement in one situation shall not affect the right of a

+party to require such performance at any time in the future. A waiver of

+performance under a provision in one situation shall not be considered a waiver

+of the performance of the provision in the future or a waiver of the provision

+in its entirety.

+

+6.4 If any provision of this Agreement is found void and unenforceable, such

+provision will be replaced to the extent possible with a provision that comes

+closest to the meaning of the original provision and which is enforceable. The

+terms and conditions set forth in this Agreement shall apply notwithstanding any

+failure of essential purpose of this Agreement or any limited remedy to the

+maximum extent possible under law.

+Creative Commons Attribution 4.0 International

+

+ Creative Commons Corporation (“Creative Commons”) is not a law firm and does not provide legal services or legal advice. Distribution of Creative Commons public licenses does not create a lawyer-client or other relationship. Creative Commons makes its licenses and related information available on an “as-is” basis. Creative Commons gives no warranties regarding its licenses, any material licensed under their terms and conditions, or any related information. Creative Commons disclaims all liability for damages resulting from their use to the fullest extent possible.

+

+Using Creative Commons Public Licenses

+

+Creative Commons public licenses provide a standard set of terms and conditions that creators and other rights holders may use to share original works of authorship and other material subject to copyright and certain other rights specified in the public license below. The following considerations are for informational purposes only, are not exhaustive, and do not form part of our licenses.

+

+Considerations for licensors: Our public licenses are intended for use by those authorized to give the public permission to use material in ways otherwise restricted by copyright and certain other rights. Our licenses are irrevocable. Licensors should read and understand the terms and conditions of the license they choose before applying it. Licensors should also secure all rights necessary before applying our licenses so that the public can reuse the material as expected. Licensors should clearly mark any material not subject to the license. This includes other CC-licensed material, or material used under an exception or limitation to copyright. More considerations for licensors.

+

+Considerations for the public: By using one of our public licenses, a licensor grants the public permission to use the licensed material under specified terms and conditions. If the licensor’s permission is not necessary for any reason–for example, because of any applicable exception or limitation to copyright–then that use is not regulated by the license. Our licenses grant only permissions under copyright and certain other rights that a licensor has authority to grant. Use of the licensed material may still be restricted for other reasons, including because others have copyright or other rights in the material. A licensor may make special requests, such as asking that all changes be marked or described. Although not required by our licenses, you are encouraged to respect those requests where reasonable. More considerations for the public.

+

+Creative Commons Attribution 4.0 International Public License

+

+By exercising the Licensed Rights (defined below), You accept and agree to be bound by the terms and conditions of this Creative Commons Attribution 4.0 International Public License ("Public License"). To the extent this Public License may be interpreted as a contract, You are granted the Licensed Rights in consideration of Your acceptance of these terms and conditions, and the Licensor grants You such rights in consideration of benefits the Licensor receives from making the Licensed Material available under these terms and conditions.

+

+Section 1 – Definitions.

+

+ a. Adapted Material means material subject to Copyright and Similar Rights that is derived from or based upon the Licensed Material and in which the Licensed Material is translated, altered, arranged, transformed, or otherwise modified in a manner requiring permission under the Copyright and Similar Rights held by the Licensor. For purposes of this Public License, where the Licensed Material is a musical work, performance, or sound recording, Adapted Material is always produced where the Licensed Material is synched in timed relation with a moving image.

+

+ b. Adapter's License means the license You apply to Your Copyright and Similar Rights in Your contributions to Adapted Material in accordance with the terms and conditions of this Public License.

+

+ c. Copyright and Similar Rights means copyright and/or similar rights closely related to copyright including, without limitation, performance, broadcast, sound recording, and Sui Generis Database Rights, without regard to how the rights are labeled or categorized. For purposes of this Public License, the rights specified in Section 2(b)(1)-(2) are not Copyright and Similar Rights.

+

+ d. Effective Technological Measures means those measures that, in the absence of proper authority, may not be circumvented under laws fulfilling obligations under Article 11 of the WIPO Copyright Treaty adopted on December 20, 1996, and/or similar international agreements.

+

+ e. Exceptions and Limitations means fair use, fair dealing, and/or any other exception or limitation to Copyright and Similar Rights that applies to Your use of the Licensed Material.

+

+ f. Licensed Material means the artistic or literary work, database, or other material to which the Licensor applied this Public License.

+

+ g. Licensed Rights means the rights granted to You subject to the terms and conditions of this Public License, which are limited to all Copyright and Similar Rights that apply to Your use of the Licensed Material and that the Licensor has authority to license.

+

+ h. Licensor means the individual(s) or entity(ies) granting rights under this Public License.

+

+ i. Share means to provide material to the public by any means or process that requires permission under the Licensed Rights, such as reproduction, public display, public performance, distribution, dissemination, communication, or importation, and to make material available to the public including in ways that members of the public may access the material from a place and at a time individually chosen by them.

+

+ j. Sui Generis Database Rights means rights other than copyright resulting from Directive 96/9/EC of the European Parliament and of the Council of 11 March 1996 on the legal protection of databases, as amended and/or succeeded, as well as other essentially equivalent rights anywhere in the world.

+

+ k. You means the individual or entity exercising the Licensed Rights under this Public License. Your has a corresponding meaning.

+

+Section 2 – Scope.

+

+ a. License grant.

+

+ 1. Subject to the terms and conditions of this Public License, the Licensor hereby grants You a worldwide, royalty-free, non-sublicensable, non-exclusive, irrevocable license to exercise the Licensed Rights in the Licensed Material to:

+

+ A. reproduce and Share the Licensed Material, in whole or in part; and

+

+ B. produce, reproduce, and Share Adapted Material.

+

+ 2. Exceptions and Limitations. For the avoidance of doubt, where Exceptions and Limitations apply to Your use, this Public License does not apply, and You do not need to comply with its terms and conditions.

+

+ 3. Term. The term of this Public License is specified in Section 6(a).

+

+ 4. Media and formats; technical modifications allowed. The Licensor authorizes You to exercise the Licensed Rights in all media and formats whether now known or hereafter created, and to make technical modifications necessary to do so. The Licensor waives and/or agrees not to assert any right or authority to forbid You from making technical modifications necessary to exercise the Licensed Rights, including technical modifications necessary to circumvent Effective Technological Measures. For purposes of this Public License, simply making modifications authorized by this Section 2(a)(4) never produces Adapted Material.

+

+ 5. Downstream recipients.

+

+ A. Offer from the Licensor – Licensed Material. Every recipient of the Licensed Material automatically receives an offer from the Licensor to exercise the Licensed Rights under the terms and conditions of this Public License.

+

+ B. No downstream restrictions. You may not offer or impose any additional or different terms or conditions on, or apply any Effective Technological Measures to, the Licensed Material if doing so restricts exercise of the Licensed Rights by any recipient of the Licensed Material.

+

+ 6. No endorsement. Nothing in this Public License constitutes or may be construed as permission to assert or imply that You are, or that Your use of the Licensed Material is, connected with, or sponsored, endorsed, or granted official status by, the Licensor or others designated to receive attribution as provided in Section 3(a)(1)(A)(i).

+

+b. Other rights.

+

+ 1. Moral rights, such as the right of integrity, are not licensed under this Public License, nor are publicity, privacy, and/or other similar personality rights; however, to the extent possible, the Licensor waives and/or agrees not to assert any such rights held by the Licensor to the limited extent necessary to allow You to exercise the Licensed Rights, but not otherwise.

+

+ 2. Patent and trademark rights are not licensed under this Public License.

+

+ 3. To the extent possible, the Licensor waives any right to collect royalties from You for the exercise of the Licensed Rights, whether directly or through a collecting society under any voluntary or waivable statutory or compulsory licensing scheme. In all other cases the Licensor expressly reserves any right to collect such royalties.

+

+Section 3 – License Conditions.

+

+Your exercise of the Licensed Rights is expressly made subject to the following conditions.

+

+ a. Attribution.

+

+ 1. If You Share the Licensed Material (including in modified form), You must:

+

+ A. retain the following if it is supplied by the Licensor with the Licensed Material:

+

+ i. identification of the creator(s) of the Licensed Material and any others designated to receive attribution, in any reasonable manner requested by the Licensor (including by pseudonym if designated);

+

+ ii. a copyright notice;

+

+ iii. a notice that refers to this Public License;

+

+ iv. a notice that refers to the disclaimer of warranties;

+

+ v. a URI or hyperlink to the Licensed Material to the extent reasonably practicable;

+

+ B. indicate if You modified the Licensed Material and retain an indication of any previous modifications; and

+

+ C. indicate the Licensed Material is licensed under this Public License, and include the text of, or the URI or hyperlink to, this Public License.

+

+ 2. You may satisfy the conditions in Section 3(a)(1) in any reasonable manner based on the medium, means, and context in which You Share the Licensed Material. For example, it may be reasonable to satisfy the conditions by providing a URI or hyperlink to a resource that includes the required information.

+

+ 3. If requested by the Licensor, You must remove any of the information required by Section 3(a)(1)(A) to the extent reasonably practicable.

+

+ 4. If You Share Adapted Material You produce, the Adapter's License You apply must not prevent recipients of the Adapted Material from complying with this Public License.

+

+Section 4 – Sui Generis Database Rights.

+

+Where the Licensed Rights include Sui Generis Database Rights that apply to Your use of the Licensed Material:

+

+ a. for the avoidance of doubt, Section 2(a)(1) grants You the right to extract, reuse, reproduce, and Share all or a substantial portion of the contents of the database;

+

+ b. if You include all or a substantial portion of the database contents in a database in which You have Sui Generis Database Rights, then the database in which You have Sui Generis Database Rights (but not its individual contents) is Adapted Material; and

+

+ c. You must comply with the conditions in Section 3(a) if You Share all or a substantial portion of the contents of the database.

+For the avoidance of doubt, this Section 4 supplements and does not replace Your obligations under this Public License where the Licensed Rights include other Copyright and Similar Rights.

+

+Section 5 – Disclaimer of Warranties and Limitation of Liability.

+

+ a. Unless otherwise separately undertaken by the Licensor, to the extent possible, the Licensor offers the Licensed Material as-is and as-available, and makes no representations or warranties of any kind concerning the Licensed Material, whether express, implied, statutory, or other. This includes, without limitation, warranties of title, merchantability, fitness for a particular purpose, non-infringement, absence of latent or other defects, accuracy, or the presence or absence of errors, whether or not known or discoverable. Where disclaimers of warranties are not allowed in full or in part, this disclaimer may not apply to You.

+

+ b. To the extent possible, in no event will the Licensor be liable to You on any legal theory (including, without limitation, negligence) or otherwise for any direct, special, indirect, incidental, consequential, punitive, exemplary, or other losses, costs, expenses, or damages arising out of this Public License or use of the Licensed Material, even if the Licensor has been advised of the possibility of such losses, costs, expenses, or damages. Where a limitation of liability is not allowed in full or in part, this limitation may not apply to You.

+

+ c. The disclaimer of warranties and limitation of liability provided above shall be interpreted in a manner that, to the extent possible, most closely approximates an absolute disclaimer and waiver of all liability.

+

+Section 6 – Term and Termination.

+

+ a. This Public License applies for the term of the Copyright and Similar Rights licensed here. However, if You fail to comply with this Public License, then Your rights under this Public License terminate automatically.

+

+ b. Where Your right to use the Licensed Material has terminated under Section 6(a), it reinstates:

+

+ 1. automatically as of the date the violation is cured, provided it is cured within 30 days of Your discovery of the violation; or

+

+ 2. upon express reinstatement by the Licensor.

+

+ c. For the avoidance of doubt, this Section 6(b) does not affect any right the Licensor may have to seek remedies for Your violations of this Public License.

+

+ d. For the avoidance of doubt, the Licensor may also offer the Licensed Material under separate terms or conditions or stop distributing the Licensed Material at any time; however, doing so will not terminate this Public License.

+

+ e. Sections 1, 5, 6, 7, and 8 survive termination of this Public License.

+

+Section 7 – Other Terms and Conditions.

+

+ a. The Licensor shall not be bound by any additional or different terms or conditions communicated by You unless expressly agreed.

+

+ b. Any arrangements, understandings, or agreements regarding the Licensed Material not stated herein are separate from and independent of the terms and conditions of this Public License.

+

+Section 8 – Interpretation.

+

+ a. For the avoidance of doubt, this Public License does not, and shall not be interpreted to, reduce, limit, restrict, or impose conditions on any use of the Licensed Material that could lawfully be made without permission under this Public License.

+

+ b. To the extent possible, if any provision of this Public License is deemed unenforceable, it shall be automatically reformed to the minimum extent necessary to make it enforceable. If the provision cannot be reformed, it shall be severed from this Public License without affecting the enforceability of the remaining terms and conditions.

+

+ c. No term or condition of this Public License will be waived and no failure to comply consented to unless expressly agreed to by the Licensor.

+

+ d. Nothing in this Public License constitutes or may be interpreted as a limitation upon, or waiver of, any privileges and immunities that apply to the Licensor or You, including from the legal processes of any jurisdiction or authority.

+

+Creative Commons is not a party to its public licenses. Notwithstanding, Creative Commons may elect to apply one of its public licenses to material it publishes and in those instances will be considered the “Licensor.” Except for the limited purpose of indicating that material is shared under a Creative Commons public license or as otherwise permitted by the Creative Commons policies published at creativecommons.org/policies, Creative Commons does not authorize the use of the trademark “Creative Commons” or any other trademark or logo of Creative Commons without its prior written consent including, without limitation, in connection with any unauthorized modifications to any of its public licenses or any other arrangements, understandings, or agreements concerning use of licensed material. For the avoidance of doubt, this paragraph does not form part of the public licenses.
