Has your organization(s) undertaken open source software development projects? If so, please describe the project, how it was executed, and the current state of this software as well as any experience with managing community contributions.
COS develops exclusively open public goods tools and services. All existing and future COS-developed software is openly licensed for permissive use. Across projects approximately 200 developers have contributed code. For example http://osf.io/ has had 123 contributors and SHARE has had 31 contributors. COS facilitates community contributions with hack-a-thons informal development sessions on-site visits and small grants to developer teams to connect services to the framework.
