Materials Commons is a system that provides researchers with space to store and share project data privately, tools for analyzing and understanding materials data, and the ability to publish data for reuse by the broader community. Along with a website [3], Materials Commons projects and datasets can be accessed via a command line tool and a Python API for custom integration into a user’s workflow. Materials Commons was designed and implemented with these key features in mind: findability, data accessibility; interoperability; and reusability.
