Patent attributes
An application versioning system and associated processes are disclosed for collaborative development of applications between a plurality of disparate network entities, as well as between a plurality of development groups within a single entity. In particular embodiments, the applications are developed within sandboxed computing environments associated with the network entities. Disparate entities, or certain groups within network entities, may be given permissioned access for downloading applications from, or uploading applications to, another entity's or group's sandboxed computing environment. Furthermore, copies of the applications may be modified, and the modifications made to the applications may be compared to prior versions of the application for merging applications into a new application version. In one embodiment, the new application version may replace prior application versions in the system.
