Document collaboration methods and systems that allow multiple users to create and edit a document are described. Such methods and systems can support devices that receive and process edits to one or more documents while the devices are off-line relative to a document collaboration service. These methods and systems can use a network based storage system (e.g., a “cloud storage platform”) to store a document (e.g., “cloud storage document”) that represents a recent collaboration state of the document based upon edits received from users who are (or have been) using the document collaboration service while one or more other users are off-line.
