What previous data archive solutions have you hosted, managed or developed? Please describe size and complexity. Has your organization undertaken projects of the scope of developing the CS?
COS maintains a free, open source infrastructure composed of a set of backend services (e.g., file storage, file rendering, authentication/authorization) and interfaces built on top of those services (e.g., OSF.io, OSF Preprints). The OSF is a scholarly commons of composable services and data archiving. The scope and complexity of the OSF significantly exceeds the requirements for The Commons. The OSF was designed from the start for enterprise-level quality for scalability, efficient extensibility via modular design, and reliable security, access, and preservation via modern solutions. Collectively, the OSF’s entirely open-source, composable suite of services consist of ~330,000 lines of code produced via 53,491 commits maintained by an expert infrastructure team of product, engineering, labs, and QA of about 40 full-time employees. OSF hosts ~14,400 gB of research data across more than 76,000 projects, 7,500 registrations, and with dozens of partners. SHARE contains more than 25 million research events harvested from ~150 providers.
COS’s modular development approach enables developers to make real contributions to the codebase right away and scale developers quickly with their motivation, ability, and accelerated learning. Many of the ASAPbio requirements for The Commons are already met with the OSF, SHARE, and OSF Preprints services. This is illustrated with established partnerships with 12 groups and consortia already for hosting their preprint services, five of which are in production as of April 2017.
