Abstract
Methods, signals, devices, and systems are provided for locating and retrieving files, objects, and other items in a network. Nametags are distributed through the network with the items. Each nametag may hold logical names identifying the item, names of the volatile copies of the item, and/or names of nonvolatile copies of the item. Thus, nametags may include names from multiple name spaces, and cached items can be identified expressly.
