Abstract: A destination inconsistency judgment apparatus, a destination inconsistency judgment method, and a medium recorded with a destination inconsistency judgment program are provided, in which a destination-information designating an information-exchange-destination is compared with a transmitter-information included in a transmitted exchangee-information, and it is judged that an inconsistency has occurred in the destination-information when the destination-information and transmitter-information are inconsistent with each other. Further, a destination inconsistency correction apparatus, a destination inconsistency correction method, and a medium recorded with a destination inconsistency correction program are provided, in which the transmitter-information is added, as the destination-information, when it is judged that an inconsistency has occurred in the destination-information.

Abstract: An information transmission apparatus, an information transmission method, and a medium recorded with an information transmission program in a store-and-forward type of electronic conference system in which operational informations representing operations performed for various objects are stored in a queue and the stored operational informations are batch transmitted, wherein there are deleted the series of informations in the operational informations stored in the queue, which do not cause any resultant changes, so that the quantity of information exchange is reduced. The sequence of informations to be transmitted is also ensured, by skipping the destination for which a transmission error has occurred upon transmission of operational informations thereto.

Abstract: An information inconsistency judgment apparatus, an information inconsistency judgment method, and a medium recorded with an information inconsistency judgment program, for judging as to whether an inconsistency has occurred in a transmitted information, based on an object at a higher level of the object to be operated, and on the registered object. An information inconsistency correction apparatus, an information inconsistency correction method, and a medium recorded with an information inconsistency correction program, for correcting the registered object based on an operational information, when it is judged that an inconsistency has occurred in the transmitted information.

Abstract: A registered information recovery processing apparatus and method in a store-and-forward type of electronic conference system, in which operation informations representing operations performed for various objects are stored is disclosed. Between information administrating devices which register and administrate the various objects, the stored operational informations are batch transmitted toward destination-information specified by information-exchange-destinations which is recorded in the information administering devices. Registered information recording devices record registered information which specifies the object registered in the information administrating devices. Recording controlling devices control recording of the registered information into the registered information recording devices.

Abstract: An object move processing apparatus, an object move processing method, and a medium recorded with an object move processing program, in a store-and-forward type of electronic conference system, in which an object creation processing and an object deletion processing are independently performed when an object move operation has been performed between different hierarchy structures, to thereby obtain a result substantially same with an object-move processing, so that the object move processing can be correctly performed regardless of a move sequence of information transmission.
