Open-source software (OSS) is computer software that is released under a license in which the copyright holder grants users the rights to use, study, change, and distribute the software and its source code to anyone and for any purpose.
It's impossible to find or create any modern software that does not rely on open-source code in its foundation.
We heavily use open-source code to develop software for both internal users and external clients and depend on it in our operations.
This guide will try to cover three main questions:
- How to properly use open-source code in closed-source projects?
- How to properly contribute to open-source?
- How to open source our code?
The OSPO team is an informal team of open-source enthusiasts and advocates in Syngenta.
We are working with R&D and digital teams to educate and assist them with:
- open-sourcing their code;
- contributing to open-source projects;
- applying the best community and industry standards and practices for their open-source projects;
- guiding on Open Source Software (OSS) licensing.
We are glad to help you with any questions you may have about open-source, licensing, best practices, etc. Talk to us via [email protected] email or MS Teams chat.
TL;DR — violation of OSS licenses may lead to lawsuits, fines, and reputation losses for the company.
Open-source software doesn't always mean we can freely use it in our projects — open-source ≠ free.
There are tens of different OSS licenses. Different licenses have different permissions, conditions and limitations for use.
Some of them, such as MIT License, are permissive — you are allowed to do almost anything. But you must keep the License text and copyright notice.
Others, such as GNU AGPLv3 are strictly copyleft. Using GNU AGPLv3 licensed library in your project — automatically requires you to open-source your project's code under the same GNU AGPLv3 license. Missing this requirement will result in a license violation — possible lawsuits, fines, and reputations losses for the company.
Some OSS software may have commercial-only licenses. This means that even if the code of such a library is open-sourced, we can't use it in our projects without buying a commercial license.
Using some Open Source License Scanning Tool (OSS License Scanner) is highly recommended to check if your project uses open-source code properly. It could be a 3-rd party service or a self-hosted tool — choose based on your project's needs and technology stack.
There are many ways we could contribute to open-source:
- Upstream our changes/features/fixes to open-source libraries.
- Publishing some of our code as open-source:
- our infrastructure and helper libraries (frameworks, etc.);
- client libraries for Syngenta's products;
- client libraries for third-party products (ORMs, wrappers, etc.);
- scientific code in the R&D environment.
- Contributions are valuable to the open-source community. It's a meaningful way to support open-source projects and the community.
- Collaborating with scientific research communities and other industrial organizations via open-source projects would benefit all parties and our industry.
- Upstreaming our changes/features/fixes reduces maintenance costs as we don't need to update our forks constantly.
- Some of our open-sourced code may receive valuable support and improvements from the open-source community.
- We may not always be able to justify the continued internal support and development of our internal code and tools. Open-sourcing such code and tools helps to preserve and continuously improve our work. This is particularly valid for scientific code.
- We should ensure that open-sourcing code will not disclose information, know-how or code that gives us a significant competitive advantage.
- We must be sure that we do not release code that does not belong to us.
- In general, we do not open source highly-specific code that we expect not to be helpful for the community.
