Abstract

A mechanism for enabling nodes on a network to collaboratively exchange sets of rendering information respecting a file. Each node maintains its own copy of the file, and each node may access its copy of the file. Whenever a node does access the locations of the file, that node sends out a rendering information message. The rendering information message comprises the set of rendering information for the file that has been updated. The rendering information message is forwarded to each of the other nodes. When each of the other nodes receives the rendering information message, it stores the set of rendering information contained therein to a rendering history associated with a user. In this manner, histories of access in the file by all users are exchanged among the nodes, and the user on each node is able to see rendering information generated by users on the other nodes.

Claims20

Dependent claims

A method for distributed review comprising:

receiving, by a first node from a second node, an identifier of a file and first positioning information identifying a first portion of the file displayed on the second node;
opening, on the first node, a copy of the file based on the identifier of the file;
identifying a second portion in the copy of the file based on the first positioning information, wherein the second portion is a copy of the first portion;
displaying the second portion on the first node;
receiving, by the first node, a stop request to stop following the second node;
after receiving the stop request and prior to receiving a resume request:
receiving, from the second node, second positioning information identifying a third portion of the file displayed on the second node at a first point in time;
receiving, from the second node, third positioning information identifying a fourth portion of the file displayed on the second node, wherein the fourth portion of the file is displayed on the second node after the third portion at a second point in time;
receiving, from the second node, fourth positioning information identifying a fifth portion of the file displayed on the second node, wherein the fifth portion of the file is displayed on the second node after the fourth portion at a third point in time;
and
storing, by the first node, in a rendering history, the second positioning information associated with the first point in time, the third positioning information associated with the second point in time, and the fourth positioning information associated with the third point in time;
receiving a resume request to resume following the second node starting at the second point in time;
and
displaying, only after receiving the resume request, a sixth portion on the first node, wherein the displaying is based on the third positioning information and the resume request to start at the second point in time, and wherein the sixth portion is a copy of the fourth portion.

11 more elements

A first node comprising:

memory;
a processor;
and
instructions, stored in the memory, for causing the processor to:
receive, from a second node, an identifier of a file and first positioning information identifying a first portion of the file displayed on the second node;
open a copy of the file based on the identifier of the file;
identify a second portion in the copy of the file based on the first positioning information, wherein the second portion is a copy of the first portion;
display the second portion on the first node;
receive a stop request to stop following the second node;
after receiving the stop request and prior to receiving a resume request:
receive, from the second node, second positioning information identifying a third portion of the file displayed on the second node at a first point in time;
receive, from the second node, third positioning information identifying a fourth portion of the file displayed on the second node, wherein the fourth portion of the file is displayed on the second node after the third portion at a second point in time;
receive, from the second node, fourth positioning information identifying a fifth portion of the file displayed on the second node, wherein the fifth portion of the file is displayed on the second node after the fourth portion at a third point in time;
and
store, in a rendering history, the second positioning information associated with the first point in time, the third positioning information associated with the second point in time, and the fourth positioning information associated with the third point in time;
receive a resume request to resume following the second node starting at the second point in time;
and
display, only after receiving the resume request a sixth portion on the first node, wherein the displaying is based on the third positioning information and the resume request to start at the second point in time, and wherein the sixth portion is a copy of the fourth portion.

15 more elements

A non-transitory machine-readable media comprising instructions for causing a processor to:

receive, by a first node from a second node, an identifier of a file and first positioning information identifying a first portion of the file displayed on the second node;
open, on the first node, a copy of the file based on the identifier of the file;
identify a second portion in the copy of the file based on the first positioning information, wherein the second portion is a copy of the first portion;
display the second portion on the first node;
receive, by the first node, a stop request to stop following the second node;
after receiving the stop request and prior to receiving a resume request:
receive, from the second node, second positioning information identifying a third portion of the file displayed on the second node at a first point in time;
receive, from the second node, third positioning information identifying a fourth portion of the file displayed on the second node, wherein the fourth portion of the file is displayed on the second node after the third portion at a second point in time;
receive, from the second node, fourth positioning information identifying a fifth portion of the file displayed on the second node, wherein the fifth portion of the file is displayed on the second node after the fourth portion at a third point in time;
and
store, by the first node, in a rendering history, the second positioning information associated with the first point in time, the third positioning information associated with the second point in time, and the fourth positioning information associated with the third point in time;
receiving a resume request to resume following the second node starting at the second point in time;
and
display, only after receiving the resume request, a sixth portion on the first node, wherein the displaying is based on the third positioning information and the resume request to start at the second point in time, and wherein the sixth portion is a copy of the fourth portion.
