Relay apparatus, client apparatus, and computer-readable medium

Abstract

A relay apparatus includes a storage, request data reception and transmission units, a mode data reception unit, a specified condition conversion unit, a content identifier reception unit, a generation unit, and a display data transmission unit. The storage stores a service identifier, access destination information, and a conversion routine for the format of a specified condition specifying content, for each of storage services. The request data reception unit receives a service identifier and a specified condition from a client apparatus. The mode data reception unit receives mode data specifying a client apparatus display format. The specified condition conversion unit converts the specified condition into a server format, which is transmitted by the request data transmission unit using access destination information. The content identifier reception unit receives content identifiers from the server, for which the generation unit generates display data. The display data transmission unit transmits it to the client apparatus.
