Abstract

Methods and apparatus, including computer program products, for communicating item disposition information between publishers and subscribers such as RFID tag readers and item tracking systems. Event routers can be used to distribute the information and an extended object naming service can be used to locate event routers. The items being tracked can have a hierarchical relationship with each other. Subscribers can choose to subscribe only to events relating to items at a particular level of the hierarchy.
