Ground is an open-source data context service; a system to manage all the peripheral information that informs the use of data. Data usage has changed both philosophically and practically in the last decade, creating an opportunity for new data context services to foster further innovation. Data context includes traditional application metadata (filesystem metadata, relational schemas, etc.) as well as behavioral context; data context also captures how these components change over time.
