What Is the License for Apache Maka? Complete Guide to Apache 2.0 Compliance

Apache Maka is released under the Apache License, Version 2.0, a permissive open-source license that grants users the right to use, modify, and distribute the code while requiring preservation of copyright notices and license text.

Understanding the licensing terms of open-source dependencies is essential for legal compliance and risk management. The Apache Maka project, maintained by the Apache Software Foundation in the apache/maka repository, uses the industry-standard Apache 2.0 license. This permissive framework allows broad commercial and non-commercial usage while providing explicit patent grants and liability protections.

Apache License 2.0 Overview

The Apache License, Version 2.0 is a permissive software license written by the Apache Software Foundation. Unlike copyleft licenses, Apache 2.0 allows you to create proprietary derivative works without requiring you to open-source your own code. The license provides an express grant of patent rights from contributors to users, protecting against patent infringement claims while maintaining minimal restrictions on software use.

License Location in the Repository

The authoritative license terms are documented in specific files at the root of the apache/maka repository.

The LICENSE File

The complete legal text resides in the LICENSE file at the repository root. This file contains the full Apache License, Version 2.0 terms as published by the Apache Software Foundation. Developers must include a copy of this license when redistributing the software or derivative works, as required by section 4(a) of the license terms.

The NOTICE File

The NOTICE file contains attribution notices and copyright statements required by section 4(d) of the Apache 2.0 license. This file preserves the intellectual property rights of contributors and must be retained in any redistributed versions, whether modified or unmodified, to ensure proper attribution is maintained.

README.md References

The README.md file provides high-level project documentation including references to the licensing structure. While not a legal document itself, it directs users to the authoritative LICENSE and NOTICE files for complete terms, ensuring developers can easily locate compliance requirements.

Source File Headers

While the license does not strictly require source file headers, the Apache Maka project follows Apache Software Foundation conventions by including standardized license headers in individual files. This practice ensures the licensing terms travel with the code when files are copied to other projects or distributed outside the original repository context.

A typical header found in JavaScript and TypeScript files within the repository follows this pattern:

/**

 * Licensed under the Apache License, Version 2.0 (the "License");
 * you may not use this file except in compliance with the License.
 * You may obtain a copy of the License at

Frequently Asked Questions

Is Apache Maka free for commercial use?

Yes. The Apache 2.0 license is a permissive license that explicitly allows commercial use, including incorporation into proprietary software sold for profit. You may use Apache Maka in production environments, SaaS offerings, or commercial products without paying licensing fees or royalties to the Apache Software Foundation, provided you comply with attribution requirements.

Do I need to open-source my code when using Apache Maka?

No. Unlike copyleft licenses such as GPL, the Apache 2.0 license does not require you to distribute your source code or use the same license for your derivative works. You can integrate Apache Maka into closed-source applications, provided you comply with attribution requirements and include the LICENSE and NOTICE files with your distribution.

What is the difference between the LICENSE and NOTICE files in Apache Maka?

The LICENSE file contains the complete Apache License, Version 2.0 legal text that governs usage rights and obligations for all users. The NOTICE file contains specific attribution statements, copyright notices, and acknowledgments required by section 4(d) of the license. While the LICENSE file is standard across all Apache 2.0 projects, the NOTICE file is unique to Apache Maka and lists the specific contributors and third-party components requiring attribution.

How do I properly attribute Apache Maka in my project?

Include a copy of the LICENSE file from the apache/maka repository in your distribution, and preserve the contents of the NOTICE file in your documentation or attributions section. If you redistribute modified versions, document your changes and ensure the copyright headers in source files remain intact. For binary distributions, include the license text in your documentation, "About" dialog, or accompanying materials.
