 Test files contain fictional holder strings as SPDX field values (for
 example "John Doe", "Jane Doe LLC", "me myself and i", "Example Corp",
 "Tools Inc", "Source Auditor Inc.", "John Smith"); they are test data,
 not notices for the files.
 .
 No upstream file carries a copyright notice (only SPDX-License-Identifier
 lines) and LICENSE.code and LICENSE.docs name no holder. README credits
 "all of the contributors to spdx/tools-golang", and RELEASE-NOTES.md
 lists them per release. Contributions are made under the Developer
 Certificate of Origin (CONTRIBUTING.md), with no copyright assignment,
 so each contributor keeps their copyright. The years span the upstream
 history (https://github.com/spdx/tools-golang): the first commit dates
 from 2018-09-11 and the v0.6.0-rc4 release from 2026-06-18.

 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

 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:
     wiki.creativecommons.org/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.
 .
      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.
 .
   c. 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.
 .
   d. 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

 other participants in various lines of business and that it is therefore
 imperative that they and their respective representatives act in a manner
 that does not violate any applicable antitrust laws and regulations. This
 License does not restrict any Contributor from engaging in similar
 specification development projects. Each Contributor may design, develop,
 manufacture, acquire or market competitive deliverables, products, and
 services, and conduct its business, in whatever way it chooses. No
 Contributor is obligated to announce or market any products or services.
 Without limiting the generality of the foregoing, the Contributors agree not

 represents and warrants that 1) it is legally entitled to grant the rights
 set forth in this License and 2) it will not intentionally include any third
 party materials in any Contribution unless those materials are available
 under terms that do not conflict with this License. IN ALL OTHER RESPECTS
 ITS CONTRIBUTIONS ARE PROVIDED "AS IS." The entire risk as to implementing
 or otherwise using the Contribution or the Specification is assumed by the
 implementer and user. Except as stated herein, CONTRIBUTOR AND LICENSEE
 EXPRESSLY DISCLAIM ANY WARRANTIES (EXPRESS, IMPLIED, OR OTHERWISE),
 INCLUDING IMPLIED WARRANTIES OF MERCHANTABILITY, NON-INFRINGEMENT, FITNESS
 FOR A PARTICULAR PURPOSE, CONDITIONS OF QUALITY, OR TITLE, RELATED TO THE
 CONTRIBUTION OR THE SPECIFICATION. IN NO EVENT WILL ANY PARTY BE LIABLE TO
 ANY OTHER PARTY FOR LOST PROFITS OR ANY FORM OF INDIRECT, SPECIAL,
 INCIDENTAL, OR CONSEQUENTIAL DAMAGES OF ANY CHARACTER FROM ANY CAUSES OF
 ACTION OF ANY KIND WITH RESPECT TO THIS AGREEMENT, WHETHER BASED ON BREACH
 OF CONTRACT, TORT (INCLUDING NEGLIGENCE), OR OTHERWISE, AND WHETHER OR NOT
 THE OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGE. Any
 obligations regarding the transfer, successors in interest, or assignment of
 Necessary Claims will be satisfied if Contributor or Licensee notifies the
 transferee or assignee of any patent that it knows contains Necessary Claims
 or necessary claims under this License. Nothing in this License requires
 Contributor to undertake a patent search. If Contributor is 1) employed by
 or acting on behalf of an employer, 2) is making a Contribution under the
 direction or control of a third party, or 3) is making the Contribution as a
 consultant, contractor, or under another similar relationship with a third
 party, Contributor represents that they have been authorized by that party
 to enter into this License on its behalf.

 expressly disclaim any warranties (express, implied, or otherwise),
 including implied warranties of merchantability, non-infringement, fitness
 for a particular purpose, or title, related to the materials. The entire
 risk as to implementing or otherwise using the materials is assumed by the
 implementer and user. IN NO EVENT WILL THE CONTRIBUTORS OR LICENSEES BE
 LIABLE TO ANY OTHER PARTY FOR LOST PROFITS OR ANY FORM OF INDIRECT, SPECIAL,
 INCIDENTAL, OR CONSEQUENTIAL DAMAGES OF ANY CHARACTER FROM ANY CAUSES OF
 ACTION OF ANY KIND WITH RESPECT TO THIS DELIVERABLE OR ITS GOVERNING
 AGREEMENT, WHETHER BASED ON BREACH OF CONTRACT, TORT (INCLUDING NEGLIGENCE),
 OR OTHERWISE, AND WHETHER OR NOT THE OTHER MEMBER HAS BEEN ADVISED OF THE
 POSSIBILITY OF SUCH DAMAGE.”
