Collaboration environments that support offline edits of shared documents

A non-statutory machine readable medium storing executable instructions which when executed by a data processing system cause the data processing system to perform a method comprising:

• establishing, at a first device, a connection to one or more servers that provide document collaboration services for multiple users to collaborate on a document processed by and stored on the one or more servers;
• receiving, at the first device, a first document that represents a recent collaboration state of the document based on changes to the document made by other devices while the first device was not connected to the one or more servers;
• applying, at the first device, one or more changes to the first document, the one or more changes based on one or more commands received at the first device while the first device was not connected to the one or more servers;
• transmitting, from the first device to the one or more servers, one or more transformed commands that are based on the one or more commands received at the first device while the first device was not connected to the one or more servers;
• and
• determining whether a second document, which was updated by the first device while the first device was not connected to the one or more servers, will be used to stay current with the recent collaboration state;
• wherein the first document is a server truth document that represents and contains the recent collaboration state of the collaboration;
• and
• wherein the first document includes an operation history that is a collection of entries, and each entry in the collection of entries includes a revision sequence number and a list of operations of all commands that were applied by the one or more servers in a server order to the first document, and wherein the collection of entries are stored in the operation history in revision sequence order based on revision sequence numbers and the operation history provides a sequential timeline of the operations of all commands that were previously applied to the first document in the server order.
