Abstract:
1. A distributed directory management system for offering a retrieval service with respect to service objects stored in object repositories located in service spaces, respectively, said system comprising a service space centralized managing mechanism, service object managing mechanisms, each corresponding to a respective one of said service spaces and the object repository located therein, service space connection managing mechanisms each corresponding to a respective one of said service spaces, and service object retrieval managing mechanisms each corresponding to a respective one of said service spaces, wherein said service space centralized managing mechanism collects mutual connection information of said service spaces from said service space connection managing mechanisms and manages the collected mutual connection information, wherein each of said service object managing mechanisms manages the object repository corresponding thereto and executes retrieval of a service object in said corresponding object repository, wherein each of said service space connection managing mechanisms implements message communication with said service object managing mechanisms to collect mutual connection information of the corresponding service space and another of said service spaces, and manages the collected mutual connection information, wherein each of said service object retrieval managing mechanisms sends a retrieval message from a user to a corresponding one of said service object managing mechanisms to request retrieval from the object repository corresponding thereto of one of the service objects stored therein, receives a result of the retrieval from said corresponding one of said service object managing mechanisms, analyzes the result of the retrieval, and produces a message to be sent to the user based on the analyzed result of the retrieval, wherein each of said service object managing mechanism sends a message indicative of the existence thereof, every time a state thereof is changed, to a corresponding one of said service space connection managing mechanisms, and wherein each of said service space connection managing mechanisms receives said message from the corresponding one of said service object managing mechanisms to update mutual connection information between the service space corresponding to said corresponding one of said service object managing mechanisms and another of said service spaces.
