Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, include sending a first electronic document to a first client device over a data network from a web server. The first electronic document includes multiple document elements formatted according to a first document schema for a first client application. The document elements include multiple content elements and one or more presence elements. Presence data is received over the data network at the web server from the first client device. The presence data includes an identification of one or more of the content elements of the first electronic document. The presence data also includes an identification of a status of the first electronic document for the first client device. An updated presence element for the first electronic document, which includes a first presence object, is stored. The first presence object includes the presence data received from the first client device and an identification of the first client device and/or a first user associated with the first client device. The first presence object is sent over the data network from the web server to a second client device.

User presence data for web-based document collaboration

Apparatus, systems, and methods may operate to receive a comment object from a first client computer, the comment object being associated with an electronic document accessed from the first client computer. Further actions may include assigning the comment object a unique identifier, placing the comment object in a queue according to the unique identifier, and forwarding the comment object to a second client computer in response to opening the electronic document by the second client computer. Additional apparatus, systems, and methods are disclosed.

Asynchronous comment updates

In various embodiments, a computerized method includes presenting an electronic document to one user out of multiple users that have edit access to the electronic document as part of a collaborative editing of the electronic document. The computerized method may include receiving an input from the user to edit the electronic document, as well as invoking a lock to prevent edit access by the other users responsive to receiving the input from the user to edit the electronic document.

Shared edit access of electronic content

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, include sending a first rich internet application over a data network from a web server to a first client device and to a second client device. The web server is adapted to allow multiple client devices to collaboratively access one or more electronic documents formatted for any one of multiple different applications, including the first rich internet application. A first electronic document, which includes multiple document elements, is sent from the web server to the first client device and to the second client device. A document update received from the first client device includes identifications of one or more of the document elements and a requested action with respect to the one or more identified document elements. The received document update is verified to determine whether the requested action complies with the document schema and whether the first client device is authorized to initiate the requested action. One or more updated document elements for the first electronic document is generated based at least in part on the verified document update and automatically sent to the second client device over the data network.

Web-based collaboration for editing electronic documents

Software load balancing is provided. In some embodiments, software load balancing includes receiving a session request from a client for a session between the client and a service associated with a set of servers, in which the set of servers includes a plurality of servers including a first server and a second server; designating the first server for the session request; sending an indication of the first server to the client in response to the session request, in which the client can communicate directly with the first server; receiving a resume session request from the client to resume the session between the client and the service associated with the set of servers; designating the second server for the resume session request; and sending a set of state information associated with the session to the second server, in which the client can communicate directly with the second server.
