Abstract: A method for saving a file stored on a third-party system to a cloud storage system includes receiving, at a cloud storage server of the cloud storage system, a save request from the third party system. The method further includes authenticating the save request, based at least in part on information identifying a user, creating a copy of the file at the cloud storage server, and associating the copy of the file with the user.

Abstract: A method for saving a file stored on a third-party system to a cloud storage system includes receiving, at a cloud storage server of the cloud storage system, a save request from the third party system. The save request is generated in response to a user selecting, via a user interface presented on a client computer, the file from a plurality of files stored on the third-party system, the file to be saved to the cloud storage server. The save request comprises a file identifier of the file and information identifying the user. The information identifying the user allows access to a user account of the user on the cloud storage system without use of the client computer as intermediary service, and the third-party system stores the file associated with the file identifier. The method further includes authenticating the save request, based at least in part on the information identifying the user, creating a copy of the file at the cloud storage server, and associating the copy of the file with the user.

Abstract: A method for providing a binary data file to at least a first client application and a second client application includes receiving a first request to access the binary data file from the first client application, and identifying a first document model associated with the binary data file, wherein the first document model reflects edits made to the binary data file by the first client application and the second client application. The method further includes transmitting data corresponding to the first document model to the first client application, receiving, from the second client application, a second request indicating a modification to the binary data file, revising the first document model associated with the binary data file to include the modification to the binary data file, and transmitting data corresponding to the revised first document model to the second client application.

Abstract: Systems and methods are disclosed herein for performing operational transforms on a document. A first operation is received at a first server that includes a first object of an electronic document. In response to receiving the first operation, the first server prohibits a second server from having write access to the first object. The first server applies the first operation to the first object to obtain a transformed first object. In response to obtaining the transformed first object, the first server allows the second server to have write access to the first object. These steps are repeated for a second object associated with a second portion of the electronic document that is different from the first portion of the electronic document.

Abstract: A document collaboration system allows applications to collaborate on a binary data file even if the binary data file is not in a collaborative document format. In response to a request from an application to access a binary data file, the document collaboration system gives the application access to a document model corresponding to the binary data file and the application If the document model does not already exist, it may be created by generating an empty document model, transmitting the binary data file to the application, and allowing the application to fill in the empty document model based on the binary data file. The document model may be provided to and modified by its related application through an application programming interface (API), and changes to the document model may be applied to the binary data file.

Abstract: A cloud storage system provides remote access to a file associated with the cloud storage system. In response to a request to access the file, the cloud storage system identifies applications available to the request generator and capable of accessing the file, which may include both online web-based applications and applications installed on a device with which the user is accessing the file. The cloud storage system determines an application type of an identified application, and provides file access to the identified application based on the application type.

Abstract: Methods and systems for providing a third party application with access to files stored on a server are disclosed. A method may include receiving, from a browser at a client device, a request for a file stored on the server, wherein the request is received via a web page provided by the third party application and rendered by the browser, the web page comprising an embedded user interface (UI) component associated with the server to access the file stored on the server, wherein the request includes a document identifier associated with the file, an application identifier of the third-party application, and an origin identifier, wherein the origin identifier is associated with the web page provided by the third party application and rendered by the browser.

Abstract: Systems and methods are described to provide consistent cross-reference between electronic documents from distributed storage servers. A first document server may receive a query relating to a first document referencing a second document. The first document is stored on the first document server, and the second document is stored on a second document server. The first document server may obtain data relating to a copy of the second document associated with a revision number. The first document server may then send, to the second document server, an update request including the revision number, and then receive from the second document server, data relating to operations that have been committed to the second document after a time associated with the revision number.

The document model may be provided to and modified by its related application through an application programming interface (API), and changes to the document model may be applied to the binary data file.

Abstract: Methods and systems provide embeddable user interface widgets to third-party applications so that the widgets can be securely embedded in, and securely used from within, the third-party applications. An embeddable widget may be authorized to access a first-party cloud storage system from a third-party application based on the cloud storage system authenticating a request received from the widget. The authentication may be based on an application identifier, an origin identifier, and/or one or more document identifiers received from the third-party application through the embedded widget. The disclosed methods and systems may significantly mitigate security concerns caused by embedding software in third-party sites, such as clickjacking.
