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. 4 | 5 | Section 1 – Definitions. 6 | 7 | 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. 8 | 9 | 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. 10 | 11 | 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. 12 | 13 | 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. 14 | 15 | 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. 16 | 17 | f. Licensed Material means the artistic or literary work, database, or other material to which the Licensor applied this Public License. 18 | 19 | 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. 20 | 21 | h. Licensor means the individual(s) or entity(ies) granting rights under this Public License. 22 | 23 | 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. 24 | 25 | 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. 26 | 27 | k. You means the individual or entity exercising the Licensed Rights under this Public License. Your has a corresponding meaning. 28 | 29 | Section 2 – Scope. 30 | 31 | a. License grant. 32 | 33 | 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: 34 | 35 | A. reproduce and Share the Licensed Material, in whole or in part; and 36 | 37 | B. produce, reproduce, and Share Adapted Material. 38 | 39 | 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. 40 | 41 | 3. Term. The term of this Public License is specified in Section 6(a). 42 | 43 | 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. 44 | 45 | 5. Downstream recipients. 46 | 47 | 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. 48 | 49 | 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. 50 | 51 | 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). 52 | 53 | b. Other rights. 54 | 55 | 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. 56 | 57 | 2. Patent and trademark rights are not licensed under this Public License. 58 | 59 | 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. 60 | 61 | Section 3 – License Conditions. 62 | 63 | Your exercise of the Licensed Rights is expressly made subject to the following conditions. 64 | 65 | a. Attribution. 66 | 67 | 1. If You Share the Licensed Material (including in modified form), You must: 68 | 69 | A. retain the following if it is supplied by the Licensor with the Licensed Material: 70 | 71 | 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); 72 | 73 | ii. a copyright notice; 74 | 75 | iii. a notice that refers to this Public License; 76 | 77 | iv. a notice that refers to the disclaimer of warranties; 78 | 79 | v. a URI or hyperlink to the Licensed Material to the extent reasonably practicable; 80 | 81 | B. indicate if You modified the Licensed Material and retain an indication of any previous modifications; and 82 | 83 | 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. 84 | 85 | 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. 86 | 87 | 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. 88 | 89 | 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. 90 | 91 | Section 4 – Sui Generis Database Rights. 92 | 93 | Where the Licensed Rights include Sui Generis Database Rights that apply to Your use of the Licensed Material: 94 | 95 | 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; 96 | 97 | 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 98 | 99 | 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. 100 | 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. 101 | 102 | Section 5 – Disclaimer of Warranties and Limitation of Liability. 103 | 104 | 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. 105 | 106 | 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. 107 | 108 | 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. 109 | 110 | Section 6 – Term and Termination. 111 | 112 | 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. 113 | 114 | b. Where Your right to use the Licensed Material has terminated under Section 6(a), it reinstates: 115 | 116 | 1. automatically as of the date the violation is cured, provided it is cured within 30 days of Your discovery of the violation; or 117 | 118 | 2. upon express reinstatement by the Licensor. 119 | 120 | 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. 121 | 122 | 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. 123 | 124 | e. Sections 1, 5, 6, 7, and 8 survive termination of this Public License. 125 | 126 | Section 7 – Other Terms and Conditions. 127 | 128 | a. The Licensor shall not be bound by any additional or different terms or conditions communicated by You unless expressly agreed. 129 | 130 | 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. 131 | 132 | Section 8 – Interpretation. 133 | 134 | 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. 135 | 136 | 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. 137 | 138 | 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. 139 | 140 | 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. 141 | 142 | Creative Commons is not a party to its public licenses.

Software package managers, audit programs, and other developer tools can read and understand `.licenserc` files, then help developers follow the rules they set. 4 | 5 | Whether strong personal conviction, company policy, or the terms of a business deal make licensing important, `.licenserc` can make it easier to respect the license terms others have chosen and ensure rights in your own work are clear. 6 | 7 | What Does a `.licenserc` File Look Like? 8 | ---------------------------------------- 9 | Here is a `.licenserc` file that allows copying of software licensed under either the [MIT License][MIT] or [version 3 of the GNU Public License][GPL-3.0], linking of software licensed under the MIT License or [version 2.0 of the Apache License][Apache-2.0], and modification of MIT-licensed software: 10 | 11 | copy: (MIT OR GPL-3.0) 12 | link: (MIT OR Apache-2.0) 13 | modify: MIT 14 | 15 | Where Do `.licenserc` Files Belong? 16 | ----------------------------------- 17 | Software programs look for files named `.licenserc` starting in the current directory. If the current directory doesn't have such a file, the search continues in the current directory's parent, its parent, and so on. 18 | 19 | File Format Details 20 | ------------------- 21 | Each line of a `.licenserc` file is either a blank line, a comment line, or a rule line. 22 | 23 | Blank lines are empty or contain only whitespace. Comment lines begin with `#`. Software ignores both blank lines and comment lines. 24 | 25 | Rule lines contain a use keyword followed by `:` and a valid [Software Package Data Exchange (SPDX) version 2.0 license expression][SPDX]. The license expression shows which open-source licenses can apply to software used in that way within the project. If there more than one rule line uses the same use keyword, only the last such rule line applies. If there isn't a rule line for a use keyword, any kind of open-source software can be used in that way. 26 | 27 | Uses and Use Keywords 28 | --------------------- 29 | `.licenserc` files may describe different rules for open-source software, depending on how that software is used in the project. Use keywords generalize different software use cases. Though the following sections include concrete examples, those examples are subject to change, and are meant only to give a general idea of what each type of use entails. Users and software projects should interpret the use keywords for themselves, in the context of specific technologies. 30 | 31 | If a `.licenserc` file is used for compliance with law, regulation, or the terms of a contract, consult an attorney. The meaning of each use keyword may be just as important as the choice of permitted licenses for achieving legal goals. 32 | 33 | ### Copy 34 | `copy` denotes rules about what kinds of open-source software a project can copy. 35 | 36 | For example, a [Node.js][Node.js] project with the following `.licenserc` file... 37 | 38 | use: MIT 39 | copy: MIT 40 | 41 | ...could, as of this writing, copy [CoffeScript][CoffeeScript] into its directory and use its `coffee` command in build scripts. 42 | 43 | ### Link 44 | `link` denotes rules about what kinds of open-source software a project can link, import, or bundle. 45 | 46 | For example, a [Ruby][Ruby] project with the following `.licenserc` file... 47 | 48 | use: Ruby 49 | link: MIT 50 | 51 | ...could, as of this writing, install [Nokogiri][Nokogiri] and `require 'nokogiri'` in its own code. 52 | 53 | ### Modify 54 | `modify` denotes rules about what kinds of open-source software a project can patch, statically or [dynamically][monkey patch], or otherwise alter. 55 | 56 | For example, a [Java][Java] project with the following `.licenserc` file... 57 | 58 | use: GPL-2.0 WITH Classpath-exception-2.0 59 | modify: Apache-2.0 60 | 61 | ...could, as of this writing, copy the source code of [PDFBox][PDFBox] and apply a custom patch to add new functionality. 62 | 63 | ### Distribute 64 | `distribute` denotes rules about what kinds of open-source software a project can distribute to users together with original code. 65 | 66 | For example, a [Python][Python] project with the following `.licenserc` file... 67 | 68 | use: Python-2.0 69 | distribute: MIT 70 | 71 | ...could, as of this writing, bundle a copy of the [s3 module][python-s3] with its own source code for distribution to users. 72 | 73 | Reference Implementation 74 | ------------------------ 75 | A [JavaScript reference implementation][licenserc.js] is available. 76 | 77 | License 78 | ------- 79 | This specification is licensed under the terms of [the Creative Commons Attribution 4.0 International Public License (CC-BY-4.0)][CC-BY-4.0].
