distributed version control for application data
Dronestore is a library that keeps objects and their attributes versioned to allow merging with different versions of the object at a later date. Upon merging two object versions, attribute values are selected according to given rules (e.g. most recent, maximum). Thus, multiple disconnected machines can modify the same object and sync changes at a later date.
