Primarily known for our work in certifying open source software licenses, the OSI’s work today has grown???just as open source has???to include a variety of member-driven working groups and incubator projects that help practitioners and communities create and share resources, furthering the open source movement. For 17 years, the OSI has brought together open source developers, organizers, contributors, advocates, and businesses toward the common goal of creation through collaboration. Our membership campaign is dedicated to furthering this vision.
