We’ve released our branched versioning system for data at http://dvid.io http://dvid.io. It’s entirely open source and uses a science HTTP API with pluggable data types and a versioned key-value backend. I’m currently developing a new backend for it: DAGStore, a lower-level ordered key-value store that will have an explicit immutable store and is tailored for distributed versioning of big data.
