Unidata hosts a variety of Open Source software projects on GitHub. We use the Open Source model because we believe strongly that broad participation in all aspects of Unidata's work is essential to achieving the Unidata community's goals. Developing software that focuses on community needs is one of our main objectives, and participation by community members in all aspects of the development process — from coding to testing, documenting, and commenting — is incredibly valuable.
As community participation in Unidata's Open Source efforts grows, we are facing increasingly complex situations surrounding contributions made to Unidata-hosted projects. As a result, we have decided to begin requiring that community members who wish to contribute code to Unidata projects on GitHub agree to the Unidata Contributor License Agreement (CLA).
