Computer object tagging

A computer readable medium comprising

• instructions thereon that when executed by at least one processor cause the at least one processor to:
• receive from a tagging application and store to a tag database, tag data for a first computer object, wherein the tag data comprises (i) an indication of a tag including at least two nested categories describing the first computer object (ii) an indication of the first computer object, and (iii) an indication of a class of users authorized to view the tag such that users within the class are permissioned, by a first user creating a new tag, to search for the newly created tag, and wherein the tag database is in communication with the at least one computer device;
• update a hierarchy of categories for computer objects to include the at least two nested categories describing the first computer object;
• receive an indication of a first category selected by a second user from a graphical representation of at least a portion of the hierarchy of categories displayed to the second user;
• cause a display of an indication of a plurality of tagged computer objects falling within the first category to the second user, wherein for each of the plurality of tagged computer objects, the second user is associated with a class permissioned to view a tag associated with the tagged computer object;
• receive a subscription request associated with the second user, wherein the subscription request comprises a description of a third user, a description of at least one tag and at least one potential action to be performed on the at least one tag by the third user;
• and
• send a notification to the second user upon the occurrence of the at least one potential action performed on the at least one tag by the third user.

A system for classifying computer objects, the system comprising:

• a server in electronic communication with a computer readable medium, the server configured to:
• receive from a tagging application and store to a tag database, tag data for a first computer object, wherein the tag data comprises (i) an indication of a tag including at least two nested categories describing the first computer object (ii) an indication of the first computer object, and (iii) an indication of a class of users authorized to view the tag such that users within the class are permissioned, by a first user creating a new tag, to search for the newly created tag, and wherein the tag database is in communication with the at least one computer device;
• update a hierarchy of categories for computer objects to include the at least two nested categories describing the first computer object;
• receive an indication of a first category selected by a second user from a graphical representation of at least a portion of the hierarchy of categories displayed to the second user;
• and
• causing a display of an indication of a plurality of tagged computer objects falling within the first category to the second user, wherein for each of the plurality of tagged computer objects, the second user is associated with a class permissioned to view a tag associated with the tagged computer object;
• receive a subscription request associated with the second user, wherein the subscription request comprises a description of a third user, a description of at least one tag and at least one potential action to be performed on the at least one tag by the third user;
• and
• send a notification to the second user upon the occurrence of the at least one potential action performed on the at least one tag by the third user.
