To promote and protect open source...

As a global non-profit, The Open Source Initiative (OSI) protects and promotes open source software, development and communities, championing software freedom in society through education, collaboration, and infrastructure, stewarding the Open Source Definition (OSD), and preventing abuse of the ideals and ethos inherent to the open source movement. See our about and history pages for more.

Open source software is software that can be freely used, changed, and shared (in modified or unmodified form) by anyone. Open source software is made by many people, and distributed under licenses that comply with the Open Source Definition.


The Faces of Open Source: Mike Dolan

We're pleased to present the eighth, but sadly, final episode of Shane Martin Coughlan's, "The Faces of Open Source Law", featuring Mike Dolan. We'd like to thank Shane for his great work in introducing the issues related to open source software and communities, as well as the people so deeply involved and committed to helping the movement succeed.
