1. A method for managing resource identifiers, the method comprising: creating a hierarchical taxonomy for a plurality of resource identifiers, wherein one or more of the plurality of resource identifiers are uniform resource identifier (URLs), and the hierarchical taxonomy being based on a plurality of tags, each of the plurality of tags being associated with at least one resource identifier of the plurality of resource identifiers and relating to a resource identified by the at least one resource identifier associated with the tag, and one or more hierarchical relationships among the plurality of tags, wherein a first tag is superior to one or more second tags and each second tag of the one or more second tags comprises a sub-taxonomy of the first tag, and wherein the one or more hierarchical relationships among the plurality of tags are provided along with one or more of the plurality of tags; categorizing the plurality of resource identifiers in accordance with the hierarchical taxonomy by: not associating a first resource identifier with said each second tag of the one or more second tags, and associating first resource identifier with the first tag; building a hierarchical view of the plurality of resource identifiers based on categorization of the plurality of resource identifiers in accordance with the hierarchical taxonomy; and displaying the hierarchical view of the plurality of resource identifiers.
