In the world of software, 'open source' is synonymous with transparency, collaboration, and innovation. But how do we maintain and protect this open approach to development? And why is understanding open-source licensing models crucial for organisations? Let's explain below.

What is open source?

Open source refers to a method of software development and distribution where the source code of a software program is freely accessible for everyone to view, use, modify, and distribute. This concept encourages collaboration and transparency, allowing developers to collaboratively enhance the software. To ensure the integrity and openness of this software, a specific license known as an open-source license is required.

What is an open-source licensing model?

These licenses, laid out in legal agreements, determine the conditions under which the software may be used and distributed. They're specifically designed to protect and guarantee users' rights and freedoms and to ensure that open-source software remains open and accessible. There are various types of open-source licensing models, each with its specific terms.

The three major open-source licensing models

There are several licensing models, each with its features. These models dictate how software is used and shared. When choosing an open-source licensing model, developers and companies must balance their needs and objectives. Each model has unique advantages and disadvantages which can vary based on usage scenarios.

Here, we delve deeper into some of the key models: GNU General Public License (GPL), MIT license, and Apache license. We highlight the benefits and challenges of some leading licensing models to provide a better understanding of their impact and applicability.

GNU General Public License (GPL)

This license mandates that any modified version of the software also be released under GPL. It promotes user freedom by preventing the source code from becoming proprietary.

Advantages of GNU General Public License (GPL)

  • Preserving Freedom: GPL promotes the freedom of software users by requiring that any changes to the source code are also released as open source. This ensures projects derived from this source code remain open.
  • Collaboration: It encourages developers' contributions to projects and promotes collaboration.

Disadvantages of GNU General Public License (GPL)

  • Limitations on Commercial Use: The GPL mandates that derivative works also be released under GPL. This means companies integrating GPL software into their products must disclose the source code. This could expose trade secrets and reduce the ability to maintain exclusive software features, potentially leading to competitive and revenue challenges.
  • Complexity: The GPL license can be legally intricate, requiring developers to be careful in adhering to the license terms.

MIT License

The MIT License, also known as the Massachusetts Institute of Technology License, is a popular and widely accepted software license in the open-source software world. The license allows developers to use, modify, and distribute the open-source software, even for commercial purposes, provided the original copyright notice is retained.

Advantages of MIT License

  • Simplicity: The MIT license is straightforward and clear, making it easy to understand and utilise the software.
  • Flexibility: The MIT license permits the software's use in both open source and commercial projects with minimal restrictions.

Disadvantages of MIT License

  • Limited Protection: The MIT license offers little protection against the software's use in closed proprietary projects. While copyright notices must be retained, there are no requirements to disclose modifications, making codes ultimately less accessible.

Apache License

This license is similar to the MIT license, allowing software to be used, modified, and distributed but also requiring changes to be documented and the licensor's name to be retained.

Advantages of Apache License

  • Clarity and Balance: The Apache license offers clear guidelines for using, modifying, and distributing the software. It also provides a balance between openness and the protection of contributors.
  • Collaboration-Friendly: The license encourages collaboration and requires source code modifications to be documented.

Disadvantages of Apache License

  • Complexity: While the Apache license is known for its flexibility, it also poses certain challenges. A primary hurdle is its legal complexity. While simpler than some other licenses like GPL, the Apache license contains detailed legal terms that can be challenging for developers unfamiliar with legal jargon. Moreover, seeking legal counsel to fully understand the license's nuances might be necessary, potentially incurring additional costs and time.

The importance of open-source licensing models for companies

Comparing and choosing an open-source licensing model is crucial for developers and businesses, as it determines the terms under which others can use and contribute to their projects. The right licensing model depends on the objectives and values of the developer and/or company, and the desired level of openness and collaboration for their software projects. Some key points to consider are:

  • Legal compliance: Companies must understand and adhere to the chosen licence to avoid legal issues.
  • Protection of intellectual property: They need to decide whether to keep their own technology as a trade secret or make it open source.
  • Commercial use: They must contemplate if they want to use open-source software in commercial applications and which licence permits that.
  • Collaboration and community contributions: The choice of the licensing model can influence community engagement and the willingness of developers to contribute.
  • Risk analysis: Companies must conduct a thorough risk assessment to understand how the selected licence may affect their present and future projects and strategies.
