Abstract

Apparatus and methods for sharing electronically rendered information between a plurality of devices over a data communications network with limited used of network data storage is described. Content may be shared automatically between members of a share group, without interactive content-sharing operations being executed by users. The embodiments include content tagging, commenting, searching, and syncing of content. Action metadata messages, that are not viewed by a user of a device, may be sent separately from content portions to notify share-group members of content to be shared. Sharing of content can be accomplished via peer-to-peer links as well as intermediary links, which may execute concurrently.

Claims

receiving an indication, at a first device of the plurality of devices, of an association of a first content tag with a first content stored on the first device, wherein the first content has been designated to be shared with at least one second device of the plurality of devices;

generating, at the first device without interaction from a user, a first action metadata message that identifies the first content to be shared with the at least one second device;

transmitting, by the first device without interaction from the user, the first action metadata message directed to the at least one second device, wherein the generating and transmitting are executed automatically responsive to the association of the first content tag with the first content;

transmitting automatically, by the first device and responsive to receiving the indication, a notification directed to a super data-storage node in the data communications network, the notification informing the super data-storage node that the content is available at the first device for transmission to the super data-storage node;

receiving, at the first device, a second action metadata message from one device of the at least one second device of the plurality of devices, wherein the second action metadata message identifies a second content that has been associated with the first content tag by the one device;

processing, automatically and without interaction from the user, the second action metadata message to identify at least one address from which the second content may be retrieved; and

retrieving, automatically and without interaction from the user, at least portions of the second content from the at least one address.

receive an indication of a first content tag being associated with a first content by a user of the first device, wherein the first content is stored at the first device and has been designated to be shared with at least one second device of a plurality of devices configured to communicate over the data communications network; and

generate, without interaction from the user, a first action metadata message that identifies the first content to be shared with the at least one second device;

transmit, without interaction from the user, the first action metadata message directed to the at least one second device, wherein the generating and transmitting are executed automatically responsive to the association of the first content tag with the first content;

transmit automatically, responsive to receiving the indication, a notification directed to a super data-storage node in the data communications network, the notification informing the super data-storage node that the content is available at the first device for transmission to the super data-storage node;

receive a second action metadata message from one device of the at least one second device of the plurality of devices, wherein the second action metadata message identifies a second content that has been associated with the first content tag by the one device;

process, automatically and without interaction from the user, the second action metadata message to identify at least one address from which the second content may be retrieved; and

retrieve, automatically and without interaction from the user, at least portions of the second content from the at least one address.

16. The computer-readable medium of claim 15, wherein the first action metadata message includes an address identifier identifying at least a first address of the first device at which a copy of the first content can be retrieved or includes a unique identifier for the first device.
