Abstract
Communication system and method for linking each of a plurality of tagged object to information services stored on a network. The system reads an object tag of one of the objects and retrieves information about the object stored on storage located at arbitrary places. To facilitate the retrieval of information, a directory is provided storing object data associating each of the objects with information services. In order to be able to handle a virtually arbitrary number of objects and information services, the directory includes a plurality of directory servers, each storing part of data base of the object data. The object data is distributed according to a defined scheme onto the plurality of directory servers in order to be able to identify the directory server storing object data associated with a particular read object tag.
