Mailing Lists

As a distributed organization, the Open Source Initiative uses mailing lists as virtual committees. These are where larger Open Source community works with the OSI's Board of Directors in fulfilling our mission to "educate and advocate" for Open Source.

Our mailing lists are public forums, and our mailing list archives are public.

The following mailing lists are open to anyone who cares about the world of Open Source, as long as you respect the charters and observe our Code of Conduct. In addition, you will want to understand the OSI's policy regarding public forums, which includes all our mailing lists, discussion forums, wikis, issue reporting systems, etc.

To promote and protect open source software and communities...

For over 20 years the Open Source Initiative (OSI) has worked to raise awareness and adoption of open source software, and build bridges between open source communities of practice. As a global non-profit, the OSI champions 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.

Open source software is made by many people and distributed under an OSD-compliant license which grants all the rights to use, study, change, and share the software in modified and unmodified form. Software freedom is essential to enabling community development of open source software.
