Versions: 2.3 · 2.1 · 2.0

This License may be referred to by its short name "TPL" (e.g., "TPL 2.2").

This License text is published by the TIE-LANG organization as a generic, reusable open source license. It may be adopted by any individual or legal entity (a "Licensor") that distributes or makes available work under this License, without any affiliation to, or endorsement by, the TIE-LANG organization.

PREAMBLE

The Tie Public License is a permissive, attribution-based open source license designed to govern the use, reproduction, modification, and distribution of any works, materials, or other subject matter of any kind — including but not limited to software and associated materials (such as source code, object code, documentation, examples, data files, datasets, media, models, and graphical assets) — that are released under it by a Licensor. It is a general-purpose, universal license: anyone may adopt it for any kind of work, and anyone may use licensed works for any purpose, in any field of endeavor.

This License is founded on and embodies the following principles:

* Permission is granted to use, copy, modify, and redistribute the Licensed Material by anyone, for any purpose, whether commercial or non-commercial, subject to the conditions set forth in this License.

* The rights of authors are respected. Attribution and notice obligations are imposed on those who use, reproduce, or redistribute the Licensed Material, and the goodwill associated with the Licensor's names and marks is protected by the trademark provisions of this License.

* The fruits of the Licensor's and Contributors' work belong to the community. Accordingly, this License expressly distinguishes between the use of the Licensed Material itself, and the creation of User Works authored by Users for or with the Licensed Material, and it protects the ownership and freedom of such User Works.

* The rights of third parties whose assets accompany the Licensed Material are respected. Where the Licensed Material is distributed together with assets owned by third parties, the licenses, notices, and attribution obligations attached to such assets are preserved and passed through, so that the rights and goodwill of every rightsholder in the distribution chain are protected.

* Universality. This License is general-purpose and field-of-use neutral. Its grants extend to every person and legal entity, without limitation by identity, affiliation, geography, or number, and to every kind of use — private, commercial, educational, research, governmental, or otherwise — subject only to the conditions expressly stated in this License.

* Fair commercial use. Commercial use of the Licensed Material is expressly permitted, and the Licensor remains free to offer separate commercial licensing arrangements. In return, commercial redistributors must preserve honest attribution and disclosure, so that the goodwill created by the Licensor's and Contributors' work accrues fairly, and so that the Licensed Material itself remains free for everyone.

This License recognizes and protects the distinction between two categories of use:

* Use of the Licensed Material itself — copying, incorporating, redistributing, or otherwise exercising the rights granted under this License over the Licensed Material. Such use is subject to the attribution and notice requirements set out in Section 4.

* Use of the Licensed Material to create User Works — creating works that You author for or with the Licensed Material (for example, programs written in a programming language distributed under this License, applications built upon a library distributed under this License, or content generated with a tool distributed under this License). Such User Works are Your own works, are not Derivative Works within the meaning of this License, and are not subject to the conditions of this License, except to the extent that they incorporate or reproduce Licensed Material source code as provided in Section 4.

This License is expressly permissive: it permits commercial use, private use, modification, and redistribution in both source and object form, including incorporation into proprietary and closed-source products, without imposing any obligation to disclose the source code of Your Derivative Works, subject to the conditions set forth in this License.

By using, copying, modifying, contributing to, or distributing any portion of the Licensed Material, You agree to be bound by the terms and conditions of this License. If You do not agree to these terms and conditions, You are not authorized to use, copy, modify, or distribute the Licensed Material.

SECTION 1 - DEFINITIONS

For the purposes of this License, the following terms have the meanings set out below. Terms defined in the singular shall be construed to include the plural, and vice versa, where the context so requires.

1.1 "Licensed Material" means, collectively, any works, materials, or other subject matter of any kind — including but not limited to: (a) the software libraries, tools, compilers, interpreters, virtual machines, runtimes, applications, plugins, extensions, and other computer programs; and (b) the documentation, source code, object code, examples, sample data, datasets, configuration files, build scripts, media files, models, hardware designs, and graphical assets (including logos and artwork) — that are (i) created by or on behalf of the Licensor, and (ii) distributed or made available by the Licensor under this License.

1.2 "Licensor" means the individual or legal entity, including its heirs, successors, and assigns, that owns the copyright in the Licensed Material and distributes or makes it available under this License.

1.3 "You" (and the corresponding possessive form "Your") means the individual or legal entity exercising permissions granted by this License.

1.4 "Source Code" means the preferred form of the Licensed Material for making modifications to it, including but not limited to programming language source files, header files, configuration files, build scripts, markup sources, style sheets, and program data that is not Object Code.

1.5 "Object Code" means any form of the Licensed Material that is not Source Code, including but not limited to compiled binaries, bytecode, machine code, intermediate or interpreted code, virtual machine images, minified or aggregated forms, and any form resulting from a mechanical transformation or translation of Source Code.

1.6 "Derivative Work" means any work — whether in Source Code or Object Code form — that is based upon, derives from, or contains or incorporates a portion of the Licensed Material, whether verbatim or with modifications, translations, adaptations, extensions, insertions, deletions, or other changes. A User Work created for or with the Licensed Material that does not incorporate or reproduce Licensed Material source code is not a Derivative Work.

1.7 "User Work" means any work of authorship — including but not limited to computer programs, applications, scripts, documents, data sets, and other creative or functional works — that You author, create, produce, or generate for or with the Licensed Material, where such work is not the Licensed Material itself and does not contain a copy of, or incorporate verbatim or with modifications, the Licensed Material's Source Code. For clarity:

(a) a work may be a User Work whether or not it is authored by a human being, and includes works authored, generated, or rendered with the aid of the Licensed Material, including works generated by artificial intelligence systems or machine learning models used for or with the Licensed Material;

(b) the fact that a User Work is authored, built, compiled, run, hosted, or otherwise materially used together with the Licensed Material — for example, a program written in a programming language distributed under this License, or an application built upon a library distributed under this License — does not, by itself, make that User Work a Derivative Work of the Licensed Material, and the source code of such a User Work is not Licensed Material source code for purposes of this License; and

(c) a User Work does not include a file of the Licensed Material itself, or a modification of such a file, even if distributed as part of a User Work.

1.8 "Contribution" means any work of authorship, including any modification or addition to the Licensed Material, that is intentionally submitted by You or by any third party to the Licensor for inclusion in the Licensed Material. "Submitted" means any form of electronic, verbal, or written communication sent to the Licensor or its representatives, including but not limited to communication on electronic mailing lists, source code control systems, issue tracking systems, code review systems, or documentation, that is intended by the sender to be considered for inclusion in the Licensed Material.

1.9 "Contributor" means any individual or legal entity that makes a Contribution.

1.10 "Brand Mark" means the names, word marks, logos, graphic devices, trade dress, service marks, and other identifying designations that the Licensor owns or controls and uses to identify the Licensed Material, the Licensor, or the family of products and services offered by the Licensor. Where the Licensor Distributes a notice file under Section 4.7, the Brand Mark includes the identifying designations designated in such notice file, but nothing in this License grants any rights in any mark not expressly designated or owned by the Licensor.

1.11 "Distribution" (and the verb "Distribute") means any act of making the Licensed Material or Derivative Works available to any third party by any means, including but not limited to sale, offer for sale, license, sublicense, transfer, conveyance, publication, uploading to a network, repository, or marketplace, inclusion in a compilation or aggregate work, public display, public performance, or provision as a hosted or managed service.

1.12 "Applicable Law" means the laws and regulations of the jurisdiction in which the relevant rights and obligations under this License are to be enforced, as determined in accordance with Section 12, together with any mandatory provisions of the laws of other jurisdictions that cannot be excluded or derogated from.

1.13 "Third-Party Material" means any work of authorship, software component, data set, font, model, media file, or other asset that (a) is neither the Licensed Material nor a Contribution; (b) is owned, licensed, or controlled by a person or entity other than the Licensor or any Contributor; and (c) is bundled with, embedded in, or made available together with the Licensed Material, whether identified in a notice file, a third-party asset manifest (however titled, such as "THIRD-PARTY-NOTICES" or "CREDITS"), or accompanying documentation.

1.14 "Third-Party Rightsholder" means the person or legal entity that owns or holds rights in Third-Party Material.

1.15 "Affiliate" means, with respect to a party, any legal entity that directly or indirectly controls, is controlled by, or is under common control with that party, where "control" means the ownership of more than fifty percent (50%) of the voting interests of the entity, or the power to direct or cause the direction of its management and policies.

SECTION 2 - GRANT OF COPYRIGHT LICENSE

Subject to the terms and conditions of this License, the Licensor and each Contributor hereby grant to You a perpetual, worldwide, non-exclusive, royalty-free, irrevocable (except as provided in Sections 3.1, 3.3, and 11) copyright license to:

2.1 Reproduce and Use — reproduce, execute, run, and use the Licensed Material, in whole or in part, in any medium, format, or context, for any purpose whatsoever, whether commercial or non-commercial, and in any field of endeavor, regardless of the identity, affiliation, or location of the user;

2.2 Modify — modify, translate, adapt, transform, port, and otherwise prepare Derivative Works of the Licensed Material;

2.3 Distribute — Distribute, sell, offer for sale, sublicense, publicly display, publicly perform, and otherwise transfer copies of the Licensed Material and Derivative Works thereof, in Source Code or Object Code form, through any channel of Distribution; and

2.4 Relicense — subject to the conditions of Section 4, grant further licenses to the Licensed Material and Derivative Works thereof under any terms You choose, including the terms of other licenses, provided that no such grant is used to evade or circumvent the conditions and obligations that this License imposes upon You.

2.5 Nature of the Grant — This License is expressly permissive with respect to Licensed Material Source Code. You are not required to disclose, publish, or release the Source Code of Your Derivative Works, and You are free to incorporate Licensed Material Source Code into proprietary, commercial, and closed-source products, provided that You comply with the attribution requirements of Section 4. The grants under this Section are made in addition to, and do not limit, any exceptions and limitations to copyright that Applicable Law provides, including without limitation fair use, fair dealing, and permitted quotation.

2.6 Universal Grant — The grants in this License are universal. They extend to every person and legal entity, without limitation by number, identity, affiliation, geography, or field of endeavor, and to every kind of use of the Licensed Material and Derivative Works thereof, whether private, commercial, educational, research, scientific, artistic, charitable, or governmental. No use case, field of use, or category of user is excluded except as expressly provided in this License.

2.7 Commercial Licensing Reservation — Nothing in this License prevents the Licensor from offering, under separate terms, licenses or waivers of any of the conditions of this License (a "Commercial License"), including in exchange for a fee or other consideration. The availability of the Licensed Material under this License does not exhaust, limit, or waive the Licensor's right to grant such Commercial Licenses, and You acquire no right to require, price, or dictate the terms of any such Commercial License.

SECTION 3 - GRANT OF PATENT LICENSE

3.1 Grant — Subject to the terms and conditions of this License, the Licensor and each Contributor hereby grant to You a perpetual, worldwide, non-exclusive, royalty-free, irrevocable (except as provided in this Section 3) patent license to make, have made, use, offer to sell, sell, import, and otherwise transfer the Licensed Material, where such license applies only to those patent claims licensable by such Licensor or Contributor that are necessarily infringed by their Contribution(s), alone or in combination with the Licensed Material to which such Contribution(s) were submitted. If You institute patent litigation against any entity (including a cross-claim or counterclaim in a lawsuit) alleging that the Licensed Material or a Contribution incorporated within the Licensed Material constitutes direct or contributory patent infringement, then any patent licenses granted to You under this License for that Licensed Material shall terminate as of the date on which such litigation is filed.

3.2 No Implied Patent License — Subject to and except as expressly provided in Section 3.1, this License does not grant, and shall not be deemed to grant, by implication, estoppel, or otherwise, any license or ownership right under any patent held or controlled by the Licensor or any Contributor. Nothing in this License shall be construed as granting You any rights under any patent claim that is not infringed by the version of the Licensed Material as made available by the Licensor.

3.3 Retaliatory Termination for Intellectual Property Claims — If You, or any of Your Affiliates, institute litigation or other formal proceedings against the Licensor, any Contributor, or any of their Affiliates (including a cross-claim or counterclaim in a lawsuit, but excluding a defensive proceeding brought solely in response to a claim first asserted against You) alleging that the Licensed Material, any Contribution, or any Derivative Work thereof constitutes direct or contributory infringement of any copyright, trademark, trade dress, patent, or other intellectual property right, then all rights and licenses granted to You under this License for the Licensed Material shall terminate as of the date on which such litigation or proceeding is filed. Termination under this Section 3.3 does not affect the rights of any other person who has received copies of the Licensed Material from You prior to such termination.

SECTION 4 - CONDITIONS OF USE AND DISTRIBUTION

The conditions in this Section apply solely to Your use and Distribution of Licensed Material Source Code and Object Code, and of Derivative Works thereof, as those terms are defined in Section 1. They do not apply to User Works You create for or with the Licensed Material. A User Work may be Distributed royalty-free and without any obligation to include copyright notices or a copy of this License, provided that it does not incorporate or reproduce Licensed Material Source Code.

4.1 Retention of Notices — Mandatory. Every use, reproduction, or Distribution of Licensed Material Source Code, whether in whole or in part, whether verbatim or modified, and whether or not conveyed to any third party, must be accompanied by:

(a) retention, in full and without alteration, of the original copyright notice and all other attribution or notice lines that accompanied the Licensed Material; and

(b) a copy of, or a direct reference (such as a Uniform Resource Locator) to, the complete text of this License, in a form that makes the License readily accessible to any person who receives, or is otherwise granted access to, the Licensed Material Source Code or any Derivative Work thereof.

4.2 Redistribution in Source Code Form — When You Distribute Licensed Material Source Code or Derivative Works thereof in Source Code form, You must retain, in every copy that You Distribute, at least the original copyright notices and the complete text of this License, without alteration.

4.3 Redistribution in Object Code Form — If You incorporate Licensed Material Source Code or Derivative Works thereof into a product that is Distributed in Object Code form or otherwise incorporated into or combined with another product or a compilation, such product or compilation must include, in the accompanying documentation or other materials that are Distributed with it, a readable copy of, or a pointer to, the original copyright notice and the complete text of this License.

4.4 Marking of Modifications — Best Effort. Where You modify a file of the Licensed Material, You are encouraged, as a matter of courtesy rather than as a strict obligation, to add a notice in the header of the modified file that indicates the nature and date of Your modification and the identity of the modifier. Compliance with this clause is a best-effort courtesy; it is not a condition precedent to the exercise of the rights granted under this License.

4.5 No Additional Restrictions — You may not impose, offer, or attempt to impose, on any recipient, any term, condition, or further restriction that alters or limits the rights or obligations granted by this License with respect to the Licensed Material, except with respect to Your own Derivative Works as permitted by Section 2.4. You may impose additional terms only on Your own Derivative Works and are solely responsible for any obligations You undertake toward recipients of such Derivative Works.

4.6 No Endorsement — The use of the Licensed Material does not imply, and shall not be represented as implying, any certification, sponsorship, endorsement, or affiliation with the Licensor or any Contributor in respect of Your Derivative Works, except as expressly permitted by Section 10.

4.7 Notice File — Optional. The Licensor may, at its option, Distribute the Licensed Material together with a plainly titled notice file (such as "NOTICE" or "NOTICES") that identifies, without limitation: (a) the Licensor's name and means of contact; (b) the Brand Mark; (c) additional attribution or credit lines required or requested by the Licensor; and (d) third-party notices that the Licensor is required to propagate, including notices for Third-Party Material as described in Section 5. Where such a notice file is provided:

(a) You must retain, in every copy that You Distribute, the substantive content of the notice file, unaltered, and must include such content in any form of redistribution that includes the Licensed Material, whether in Source Code or Object Code form; and

(b) You may add Your own notices to the notice file, but such additions must be clearly identified as Your own and must not misrepresent, obscure, or remove the notices of the Licensor or of any third party.

Nothing in this Section 4.7 obliges a Licensor to provide a notice file, and the absence of a notice file shall not diminish or alter any other obligation under this License.

4.8 Hosted Services — Where the Licensed Material or a Derivative Work thereof is made available as a hosted or managed service within the meaning of Section 1.11, the obligations of Sections 4.1 to 4.3 are deemed satisfied if the copyright notices described in Section 4.1(a) and either a copy of, or a direct reference (such as a Uniform Resource Locator) to, the complete text of this License are made readily accessible to the users of such service, for example in the service documentation, an "about" page, or the terms of service. Nothing in this Section 4.8 imposes on You any obligation to disclose the Source Code of the service or of any Derivative Work operated as a hosted service.

4.9 Conspicuous Attribution — Where You incorporate Licensed Material Source Code or Derivative Works thereof into a product that is Distributed to end users, the notices required by Sections 4.1 to 4.3 must be presented in a form that is reasonably conspicuous and accessible to the recipients of the product, including, where the product provides an "About", "Credits", "Legal Notices", or similar section, by inclusion in that section. Placement solely in machine-readable files, installer logs, or other locations not reasonably accessible to end users does not satisfy this Section for products Distributed to end users, without prejudice to the sufficiency of such placement for other forms of Distribution.

4.10 Honest Commercial Distribution — You may charge for the Distribution of the Licensed Material or Derivative Works thereof. However, You shall not: (a) represent that the Licensed Material itself is proprietary software or licensed exclusively to You; (b) impose on any recipient of the Licensed Material any restriction on that recipient's rights under this License; or (c) where You Distribute the Licensed Material itself, as opposed to a Derivative Work or a larger product incorporating it, for a fee, fail to disclose clearly that the Licensed Material is also available free of charge under this License. This Section does not prevent You from charging for Your Derivative Works, additional software, services, support, maintenance, or warranties.

SECTION 5 - THIRD-PARTY MATERIAL

5.1 Identification and Separate Terms — The Licensed Material may be Distributed together with, embed, depend upon, or reference Third-Party Material. Third-Party Material is not Licensed Material, is not a Contribution, and is not licensed to You under this License. Nothing in this License grants, limits, or modifies any rights or obligations with respect to Third-Party Material; such rights and obligations are governed exclusively by the terms under which the relevant Third-Party Rightsholder makes it available.

5.2 Compliance with Third-Party Terms — Mandatory. When You use, reproduce, modify, or Distribute the Licensed Material in any form that includes, conveys, or is accompanied by Third-Party Material, You must comply, to the extent applicable, with all terms, conditions, and obligations under which such Third-Party Material is made available, including but not limited to the retention of third-party copyright, license, attribution, and disclaimer notices, and any obligation to provide source code or a written offer thereof, as required by the license of such Third-Party Material.

5.3 Retention of Third-Party Notices — Where the Licensor has Distributed a notice file under Section 4.7 or a third-party asset manifest identifying Third-Party Material and its Third-Party Rightsholders, You must retain the substantive content of such third-party notices, unaltered, in every copy that You Distribute which includes the corresponding Third-Party Material, and must include such content in any redistribution in Source Code or Object Code form.

5.4 No Removal or Misrepresentation — You shall not remove, alter, obscure, or falsify any copyright, license, attribution, or disclaimer notice pertaining to Third-Party Material; shall not represent Third-Party Material as Your own original work or as being licensed under this License; and shall not use this License to relicense, sublicense, or restate the terms of Third-Party Material.

5.5 Conflict of Terms — Where the license terms applicable to an item of Third-Party Material conflict with this License, those terms prevail solely with respect to that item of Third-Party Material, and this License continues to govern the remainder of the Licensed Material.

5.6 No Warranty of Third-Party Rights — The Licensor makes no representation or warranty regarding Third-Party Material, including as to its title, licensing status, or non-infringement of third-party rights. Any warranty, support, or indemnity relating to Third-Party Material is governed exclusively by the terms of such Third-Party Material.

5.7 Enforcement — Each Third-Party Rightsholder is an intended third-party beneficiary of Sections 4.7, 5.2, 5.3, and 5.4 with respect to its Third-Party Material, and may directly enforce those provisions against You to the extent necessary to protect its rights in its Third-Party Material. For the purposes of Section 11.2, a breach of Sections 5.2 to 5.4 constitutes a material breach of this License.

SECTION 6 - USER WORKS CREATED WITH THE LICENSED MATERIAL

6.1 Ownership — User Works that You create for or with the Licensed Material are Your own works. Except to the extent that such User Works incorporate or reproduce Licensed Material Source Code as provided in Section 4, this License grants no rights in, and imposes no obligations with respect to, Your User Works.

6.2 No Attribution on User Works — You are not required to include any copyright notice, license text, attribution statement, trademark, or link to this License in, or in connection with, any User Work that You create for or with the Licensed Material, provided that such User Work does not incorporate or reproduce Licensed Material Source Code.

6.3 No Copyleft — Nothing in this License requires You to license, publish, disclose, or release the Source Code of Your User Works or Derivative Works under this License or under any other license, and no act of receiving or using the Licensed Material shall be construed as a consent to any obligation to do so.

6.4 Artificial Intelligence and Machine Learning — For the purposes of this License:

(a) the reproduction of the Licensed Material for the purpose of training, fine-tuning, evaluating, or otherwise improving a machine learning model or artificial intelligence system (a "Model") constitutes a use and reproduction of the Licensed Material permitted under Section 2, subject to the notice obligations of Section 4.1 with respect to any retained copy of Licensed Material Source Code;

(b) the weights, parameters, and other learned artifacts of a Model so trained are not Object Code, not Derivative Works, and not Licensed Material;

(c) output generated by a Model is a User Work of the person or entity that generates it, whether or not the Model was trained on the Licensed Material, and shall not, by that fact alone, be deemed a Derivative Work of the Licensed Material or subject to the conditions of this License; provided that, to the extent an output incorporates or reproduces Licensed Material Source Code, that portion remains subject to Section 4; and

(d) no attribution, notice, or license obligation under this License attaches to Model outputs by reason of training alone.

SECTION 7 - SUBMISSION OF CONTRIBUTIONS

7.1 License Grant to the Licensor — Unless You explicitly state otherwise, any Contribution that You intentionally submit for inclusion in the Licensed Material shall be under the terms and conditions of this License, without any additional terms or conditions. Notwithstanding the foregoing, nothing in this License shall supersede or modify the terms of any separate license agreement that You may have executed with the Licensor regarding such Contributions.

7.2 Representations and Warranties — By submitting a Contribution, You represent and warrant that:

(a) You have the full legal right, power, and authority to grant the licenses granted in Section 7.1, free and clear of all encumbrances and third-party claims;

(b) the Contribution is Your original creation; and

(c) to the extent that the Contribution is not Your original creation, You have identified the third-party source of the Contribution to the Licensor in a written notice, and You have obtained, or ensured that the Licensor may obtain, all rights and permissions necessary to incorporate and license the Contribution in accordance with this License.

7.3 No Obligation to Accept — Nothing in this License obligates the Licensor to accept, incorporate, integrate, or otherwise use any Contribution.

7.4 Moral Rights — To the fullest extent permitted by Applicable Law, by submitting a Contribution You waive any and all moral rights, including rights of attribution and integrity, that may be held by You in such Contribution in favor of the Licensor, subject always to the attribution and notice obligations imposed by this License.

SECTION 8 - DISCLAIMER OF WARRANTY

THE LICENSED MATERIAL IS PROVIDED BY THE LICENSOR AND CONTRIBUTORS "AS IS" AND ON AN "AS AVAILABLE" BASIS, WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS, IMPLIED, OR STATUTORY, INCLUDING BUT NOT LIMITED TO THE IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, ACCURACY, NON-INFRINGEMENT, AND ANY WARRANTIES ARISING FROM COURSE OF DEALING, COURSE OF PERFORMANCE, OR USAGE OF TRADE.

NO WARRANTY IS MADE THAT THE LICENSED MATERIAL WILL BE UNINTERRUPTED, TIMELY, SECURE, OR ERROR-FREE, THAT DEFECTS WILL BE CORRECTED, THAT RESULTS OBTAINED FROM THE USE OF THE LICENSED MATERIAL WILL BE ACCURATE OR RELIABLE, OR THAT THE LICENSED MATERIAL WILL OPERATE IN COMBINATION WITH YOUR HARDWARE, SOFTWARE, SYSTEMS, OR DATA.

TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, THE ENTIRE RISK ARISING OUT OF THE USE OF THE LICENSED MATERIAL REMAINS WITH YOU. THIS LICENSE IS GRANTED BY THE LICENSOR AND EACH CONTRIBUTOR INDIVIDUALLY, AND NO LICENSOR OR CONTRIBUTOR MAKES ANY REPRESENTATION OR WARRANTY ON BEHALF OF ANY OTHER LICENSOR OR CONTRIBUTOR.

SECTION 9 - LIMITATION OF LIABILITY

TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT SHALL THE LICENSOR OR ANY CONTRIBUTOR BE LIABLE TO YOU OR TO ANY THIRD PARTY FOR ANY DIRECT, INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES (INCLUDING BUT NOT LIMITED TO: PROCUREMENT OF SUBSTITUTE GOODS OR SERVICES; LOSS OF USE, DATA, PROFITS, REVENUE, OR GOODWILL; BUSINESS INTERRUPTION; LOSS OF PRIVACY; OR ANY LOSS OR DAMAGE ARISING OUT OF YOUR OR A THIRD PARTY'S USE OF, OR INABILITY TO USE, THE LICENSED MATERIAL) HOWEVER CAUSED AND ON ANY THEORY OF LIABILITY, WHETHER IN CONTRACT, TORT (INCLUDING NEGLIGENCE OR OTHERWISE), STRICT LIABILITY, OR OTHERWISE, ARISING IN ANY WAY OUT OF THE USE OF, OR INABILITY TO USE, THE LICENSED MATERIAL, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

WHERE APPLICABLE LAW PROHIBITS THE EXCLUSION OR LIMITATION OF CERTAIN LIABILITIES OR DAMAGES, THE FOREGOING LIMITATIONS AND EXCLUSIONS SHALL APPLY TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, AND ANY LIABILITY THAT CANNOT BE EXCLUDED OR LIMITED UNDER APPLICABLE LAW SHALL BE GOVERNED BY SUCH APPLICABLE LAW.

SECTION 10 - TRADEMARK PROVISIONS

10.1 Ownership — The Brand Mark is owned exclusively by the Licensor. This License grants You no rights of any kind in or to the Brand Mark. Nothing in Sections 2 through 9 confers, by implication, estoppel, or otherwise, any trademark, service mark, trade name, trade dress, or logo rights, or any right to use the Brand Mark.

10.2 Permitted Use — Without prior written authorization from the Licensor, You may:

(a) use the Licensed Material to create and Distribute Your own User Works and Derivative Works under Your own terms, subject to the conditions of Section 4;

(b) refer to the Brand Mark nominatively and descriptively in documentation, source code comments, presentations, marketing materials, and truthful factual statements, including statements of interoperability, compatibility, or provenance (for example, "built with [Licensed Material]", "targets [Licensed Material]", "compatible with [Licensed Material]"); and

(c) use the Brand Mark to identify that a User Work or implementation is compatible with, targets, or interoperates with the Licensed Material, provided that such use is accurate, truthful, and not likely to confuse any person as to source, sponsorship, affiliation, or endorsement.

10.3 Prohibited Use — Without the prior express written authorization of the Licensor, You shall not:

(a) use the Brand Mark, or any confusingly similar variant thereof, as, or as part of, the name, title, service mark, or branding of Your own products, services, tools, implementations, packages, software, domain names, or companies, in a manner that is likely to cause confusion with the Licensor or with the Licensed Material;

(b) reproduce, modify, transform, distort, or create derivative logos or graphic devices based upon the Brand Mark, including the logo, icon, and graphic assets Distributed with the Licensed Material;

(c) use the Brand Mark in any manner that could reasonably imply that Your products or services are officially supported, certified, endorsed, sponsored, or affiliated with the Licensor, or that the Licensor originated or endorses Your work; or

(d) use the Brand Mark in any manner that diminishes, dilutes, tarnishes, or damages the goodwill associated with the Brand Mark, or that otherwise violates Applicable Law relating to trademarks, unfair competition, or misleading advertising.

10.4 Enforcement — The Licensor reserves the right to enforce its rights in the Brand Mark by all legal and equitable means available under Applicable Law, including but not limited to requesting corrective action, seeking injunctive relief, and claiming damages for unauthorized use.

SECTION 11 - TERMINATION

11.1 Termination for Breach — This License and the rights granted hereunder will terminate automatically, without notice, upon Your breach of any term of this License, unless the breach is cured within thirty (30) days after You become aware of, or are notified of, the noncompliance.

11.2 Material Breach — Failure to comply with the mandatory attribution, notice, and third-party compliance obligations of Sections 4 and 5 with respect to the use or Distribution of Licensed Material Source Code constitutes a material breach of this License. If such a breach is not cured within thirty (30) days after You become aware of, or are notified of, the noncompliance, the rights granted under this License shall terminate automatically upon the expiration of that cure period, and You shall cease all use, reproduction, and Distribution of the Licensed Material Source Code until such breach is cured. If the breach is cured within the cure period, this License and the rights granted hereunder shall continue in full force and effect and shall be deemed never to have terminated by reason of that breach.

11.3 User Works Not Affected — For the avoidance of doubt, no breach of this License shall be deemed to occur solely by virtue of Your use or Distribution of User Works created for or with the Licensed Material that do not incorporate or reproduce Licensed Material Source Code.

11.4 Effect of Termination — Upon termination, all licenses granted to You under this License shall terminate, and Your rights to use, modify, and Distribute the Licensed Material shall cease forthwith. Sections 5.7, 8, 9, 10, 11.4, 11.6, 12, 14, and 15 shall survive any termination. If You have sublicensed any Derivative Work prior to termination, such sublicenses shall survive termination only to the extent that they do not violate the terms of this License.

11.5 Reinstatement — Rights terminated under this Section 11 may, at the sole discretion of the Licensor, be reinstated upon Your cure of the breach and written notification to the Licensor of such cure.

11.6 Enforcement Costs — In any action or proceeding to enforce or interpret this License, the prevailing party shall be entitled to recover its reasonable attorneys' fees and costs, to the extent permitted by Applicable Law.

SECTION 12 - GOVERNING LAW AND JURISDICTION

12.1 Governing Law — The Licensor may designate the governing law for this License by a Designation as described in Section 12.2. In the absence of an effective Designation, this License shall be governed by and construed in accordance with the laws of the jurisdiction in which the Licensor is domiciled, without regard to its conflict-of-laws provisions.

12.2 Jurisdiction and Designation — The Licensor may, in the notice file distributed under Section 4.7, in the LICENSE file accompanying the Licensed Material, or in other documentation distributed with the Licensed Material, expressly designate a specific governing law and/or the competent courts of a specific jurisdiction (a "Designation"), provided that such Designation is plainly identified as being made under this Section 12.2. Subject to any effective Designation, any dispute, controversy, or claim arising out of or relating to this License, or to the breach, termination, or validity thereof, shall be subject to the exclusive jurisdiction of the competent courts of the jurisdiction in which the Licensor is domiciled.

12.3 Mandatory Provisions — Where any jurisdiction requires that its mandatory laws or public policy be applied notwithstanding the choice of law made in Section 12.1, the provisions of such jurisdiction shall prevail to the extent that they cannot be excluded by agreement, and the remainder of this License shall continue in full force and effect.

SECTION 13 - SEVERABILITY AND WAIVER

13.1 Severability — If any provision, or portion of a provision, of this License is held to be invalid, illegal, or unenforceable under Applicable Law, such provision shall be construed, interpreted, and reformed to the maximum extent possible to achieve the intent of the parties, and the remaining provisions of this License shall continue in full force and effect.

13.2 Waiver — No waiver of any term of this License shall be effective unless in writing and signed by the party against whom the waiver is asserted. The failure of the Licensor to exercise or enforce any right or provision of this License shall not constitute a waiver of such right or provision, and no single or partial exercise of any right or provision shall preclude any other or further exercise thereof.

SECTION 14 - ENTIRE AGREEMENT AND AMENDMENT

14.1 Entire Agreement — This License constitutes the entire agreement between You and the Licensor with respect to the Licensed Material and supersedes all prior and contemporaneous understandings, agreements, representations, and communications, whether oral or written, regarding such subject matter.

Electronic signatures and other forms of electronic authentication shall be given the same legal effect and validity as original written signatures to the fullest extent permitted by Applicable Law.

14.3 Continued Application — Each version of the Licensed Material is governed by the version of this License under which it was released. If the Licensor releases the Licensed Material under a later version of this License, You may continue to exercise Your rights under, and distribute and relicense, prior versions of the Licensed Material under the version of this License under which they were released.

SECTION 15 - GENERAL PROVISIONS

15.1 Compliance with Laws — You shall comply with all Applicable Law, including but not limited to export control laws, import laws, and sanctions laws, in exercising the rights granted under this License. You shall not use the Licensed Material in any manner that violates Applicable Law.

15.5 Third-Party Beneficiaries — Subject to the terms of this License, each Contributor is an intended third-party beneficiary of this License with respect to its Contributions, and may directly enforce the terms of this License against You to the extent necessary to protect its rights in its Contributions. Each Third-Party Rightsholder is an intended third-party beneficiary of this License with respect to its Third-Party Material, to the extent provided in Section 5.7.

15.6 License Text — The text of this License may be reproduced in whole, verbatim and unaltered, by any person, for any purpose, including for the purpose of complying with the notice requirements of Section 4, without the need for any additional permission or attribution beyond the retention of this License text itself.

APPENDIX - HOW TO APPLY THE TIE PUBLIC LICENSE TO YOUR WORK

To apply the Tie Public License to your work, attach the following notices to the work. It is safest to attach them to the start of each source file to most effectively state the terms of this License; each file should have at least the "copyright" line and a pointer to where the full notice is found.

<one line to give the program's name and a brief idea of what it does.> Copyright (C) <year> <name of copyright holder>

This program is released under the Tie Public License (the current version, e.g., "TPL 2.2"). The full text of the license is available in the LICENSE file at the root of the distribution, or online at https://github.com/tie-lang/TPL/blob/main/tpl.txt (the canonical, always-current text of this License).

If the program does terminal interaction, make it output a short notice like this when it starts in an interactive mode:

<program> Copyright (C) <year> <name of copyright holder> This program comes with ABSOLUTELY NO WARRANTY; for details see the LICENSE file. This is free software, and you are welcome to redistribute it under certain conditions; see the LICENSE file for details.

If your distribution includes Third-Party Material within the meaning of Section 5, ensure that all third-party notices, asset manifests, and license texts accompanying such material are preserved and conveyed with every copy, in accordance with Sections 5.2 and 5.3.

If You intend to designate a governing law or venue pursuant to Section 12.2, state the Designation plainly in the LICENSE file or notice file, identifying it as a designation under Section 12.2 of the Tie Public License.

You should also get your employer (if you work as a programmer) or school, if any, to sign a "copyright disclaimer" for the program, if necessary. For more information on this, and how to apply and document license terms, see <uniform resource locator to guidance or the Licensor's documentation>.

The Licensor's name and Brand Mark may not be used to endorse or promote works derived from the Licensed Material without the Licensor's prior written permission, or, where the law provides for such use, in a non-confusing manner in compliance with Section 10. For enquiries regarding the use of the Licensor's name or Brand Mark, please contact the Licensor.
