Channel sharing

A data processing system used for delivering profile data structures that contain interest nodes or channels. The interest nodes include sets of targets and qualifiers that comprise attributes used in filtering information files for delivery. Targets and qualifiers are applied to the attributes and available information files to produce the filtered set. Web pages showing results include tools to assist the user in creation and editing of the information. The user may share interest nodes with other users, and other users may be granted editing capability of the interest nodes. The other users may modify the interest nodes for their own personal use. Even if modified the user may continue to receive new content or information from the original user in accordance with the unmodified interest nodes or channels.
