Abstract

Methods and systems for online collaboration. A method embodiment facilitates collaborative editing of a cloud-based shared document using a browser-enabled platform native application. A user launches a platform native application and establishes a non-browser connection between the platform native application and a remote cloud-based shared file facility. The non-browser connection operates independently from any browser connections even though the platform native application includes a document editor web app within the embedded browser. A first user retrieves a first user copy of the cloud-based shared document, modifies the document, and shares the modified document so as to be accessible by other collaborating users.

First claim

What is claimed is:

1. A method for collaborative editing of a cloud-based shared document using a browser-enabled platform native application, the method comprising:
providing shared access to a document that is stored in a remote cloud-based shared file facility;
launching a platform native application from a user device of a first collaborating user;
establishing a non-browser connection between the platform native application and the remote cloud-based shared file facility, wherein the non-browser connection operates independently from a browser connection, wherein the non-browser connection is a connection over a communications protocol, and wherein the non-browser connection is an authenticated connection;
launching, by the platform native application an embedded browser that operates within the platform native application;
loading, by the embedded browser over a browser connection, a web application that executes within the embedded browser;
retrieving, from the remote cloud-based shared file facility a first user copy of the cloud-based shared document, wherein the first user copy of the cloud-based shared document is accessible by the web application; and
sending a modification of the first user copy of the cloud-based shared document to the remote cloud-based shared file facility to create a modified document that is exposed to one or more second collaborating users.

2. The method of claim 1 , wherein the platform native application manages state transitions between at least two of, an active-online state, an active-offline state, an inactive-offline state or, an inactive-online state.

3. The method of claim 2 , wherein the non-browser connection between the platform native application and the remote cloud-based shared file facility remains open during state transitions between at least two of, an active-online state, an active-offline state, an inactive-offline state or, an inactive-online state.

4. The method of claim 1 , wherein the non-browser connection between the platform native application and the remote cloud-based shared file facility is a websocket connection over a websocket protocol.

5. The method of claim 1 , further comprising:
closing the first user copy of the cloud-based shared document,
receiving, by the platform native application over the non-browser connection, at least one modification to the cloud-based shared document that originates from one of the one or more second collaborating users, and
applying the at least one modification to the first user copy before the first collaborating user reopens the first user copy of the cloud-based shared document.

6. The method of claim 1 , wherein the embedded browser is formed from all or portions of, Node.js, GitHub's Electron, WebKit, Chromium, Gecko, etc.

7. The method of claim 1 , wherein at least one representation of the modification is given as an operational transform.

8. The method of claim 7 , wherein at least one operational transform is communicated between an operational transform pair formed by a server-side operational transformation protocol engine and a client-side operational transformation protocol engine.

9. The method of claim 1 , further comprising performing at least a portion of a client-local operational transformation protocol wherein local operational transformation pair data is received by a local operational transformation protocol engine.

10. The method of claim 9 , wherein the client-local operational transformation protocol is performed when the user device is not connected to the remote cloud-based shared file facility.

11. The method of claim 10 , wherein the local operational transformation protocol engine synchronizes with a client-side operational transformation protocol engine.

12. A non-transitory computer readable medium having stored thereon a sequence of instructions which, when executed by one or more processors causes a set of acts for collaborative editing of a cloud-based shared document using a browser-enabled platform native application, the set of acts comprising:
providing shared access to a document that is stored in a remote cloud-based shared file facility;
launching a platform native application from a user device of a first collaborating user;
establishing a non-browser connection between the platform native application and the remote cloud-based shared file facility, wherein the non-browser connection operates independently from a browser connection, wherein the non-browser connection is a connection over a communications protocol, and wherein the non-browser connection is an authenticated connection;
launching, by the platform native application an embedded browser that operates within the platform native application;
loading, by the embedded browser over a browser connection, a web application that executes within the embedded browser;
retrieving, from the remote cloud-based shared file facility a first user copy of the cloud-based shared document, wherein the first user copy of the cloud-based shared document is accessible by the web application; and
sending a modification of the first user copy of the cloud-based shared document to the remote cloud-based shared file facility to create a modified document that is exposed to one or more second collaborating users.

13. The non-transitory computer readable medium of claim 12 , wherein the platform native application manages state transitions between at least two of, an active-online state, an active-offline state, an inactive-offline state or, an inactive-online state.

14. The non-transitory computer readable medium of claim 13 , wherein the non-browser connection between the platform native application and the remote cloud-based shared file facility remains open during state transitions between at least two of, an active-online state, an active-offline state, an inactive-offline state or, an inactive-online state.

15. The non-transitory computer readable medium of claim 12 , wherein the non-browser connection between the platform native application and the remote cloud-based shared file facility is a web socket connection over a websocket protocol.

16. The non-transitory computer readable medium of claim 12 , wherein the set of acts further comprises:
closing the first user copy of the cloud-based shared document,
receiving, by the platform native application over the non-browser connection, at least one modification to the cloud-based shared document that originates from one of the one or more second collaborating users, and
applying the at least one modification to the first user copy before the first collaborating user reopens the first user copy of the cloud-based shared document.

17. The non-transitory computer readable medium of claim 12 , wherein the embedded browser is formed from all or portions of, Node.js, GitHub's Electron, WebKit, Chromium, Gecko, etc.

18. The non-transitory computer readable medium of claim 12 , wherein at least one representation of the modification is given as an operational transform.

19. A system for collaborative editing of a cloud-based shared document using a browser-enabled platform native application, the system comprising:
a storage medium having stored thereon a sequence of instructions; and
one or more processors that execute the sequence of instructions to cause the one or more processors to perform a set of acts, the set of acts comprising,
providing shared access to a document that is stored in a remote cloud-based shared file facility,
launching a platform native application from a user devi
