Web-based multiuser collaboration

A system for web-based multiuser collaboration, the system comprising:

• a processor;
• and
• an optical disk, magnetic storage device, or semiconductor storage device having executable instructions stored thereupon which, when executed by the processor, cause the processor to
• model a document on a server into semantic pieces as a plurality of cells for a construct of the document,
• identify at least one cell of interest of the plurality of cells to at least one user of a plurality of users, the at least one cell of interest comprising a portion of the document cached on the server,
• in response to identifying the at least one cell of interest, send the cached portion of the at least one cell of interest to a browser associated with the at least one user,
• associate the at least one cell of interest with the at least one user,
• store an association between the at least one cell of interest and the at least one user,
• obtain a first revision of interest to the at least one cell of interest,
• determine, based upon the association between the at least one cell of interest and the at least one user, that the first revision of interest is to be sent to the browser associated with the at least one user, and
• send a cached portion of the first revision of interest to the browser associated with the at least one user, whereby the cached portion of the first revision is configured to be displayed by the browser along with a first identifier indicating the association between the at least one cell of interest and the at least one user.

An optical, magnetic, or semiconductor computer-readable storage medium having instructions stored thereon which, when executed by a processor of a computing system, cause the computing system to perform operations comprising:

• modeling a document on a server into semantic pieces as a plurality of cells for a construct of the document;
• identifying at least one cell of interest of the plurality of cells to at least one user of a plurality of users, the at least one cell of interest comprising a portion of the document cached on the server;
• in response to identifying the at least one cell of interest, sending the cached portion of the at least one cell of interest to a browser associated with the at least one user;
• associating the at least one cell of interest with the at least one user;
• storing an association between the at least one cell of interest and the at least one user;
• obtaining a first revision of interest to the at least one cell of interest;
• determining, based upon the association between the at least one cell of interest and the at least one user, that the first revision of interest is to be sent to the browser associated with the at least one user;
• and
• sending a cached portion of the first revision of interest to the browser associated with the at least one user, whereby the cached portion of the first revision is displayed by the browser along with a first identifier indicating the association between the at least one cell of interest and the at least one user.
