A relay apparatus includes a storage, and request data reception and transmission units, first and second conversion units, and content identifier reception and transmission units. For each storage service, the storage stores a service identifier, access destination information, and a conversion routine for converting a content identifier and a specified condition for specifying content between a server format and a client apparatus format. The request data reception unit receives a service identifier and a specified condition from a client apparatus. The first conversion unit converts the specified condition into a server format. The request data transmission unit transmits the resulting specified condition according to the access destination information. The content identifier reception unit receives a content identifier from a server. The second conversion unit converts the received content identifier into the client apparatus format. The content identifier transmission unit transmits the resulting content identifier to the client apparatus. |

1. A relay apparatus comprising:
a storage that stores a service identifier, access destination information, and a conversion routine in such a manner that the service identifier, the access destination information, and the conversion routine are associated with each other, for each of a plurality of storage services, the service identifier being an identifier for identifying the storage service, the access destination information indicating information used to access a server which provides the storage service, the conversion routine indicating a rule for converting a content identifier for identifying content and a specified condition indicating a condition used to specify one or more pieces of content between a format used in the server providing the storage service and a format used in a client apparatus; a request data reception unit that receives first request data including a service identifier and a specified condition from the client apparatus; a first conversion unit that converts the specified condition included in the first request data into the format used in the server, in accordance with a conversion routine stored in the storage in such a manner that the conversion routine is associated with the service identifier included in the first request data received by the request data reception unit; a request data transmission unit that transmits second request data including the specified condition obtained through the conversion performed by the first conversion unit, in accordance with the access destination information stored in the storage in such a manner that the access destination information is associated with the service identifier included in the first request data received by the request data reception unit; a content identifier reception unit that receives a content identifier transmitted from the server as a response to the second request data transmitted by the request data transmission unit; a second conversion unit that converts the content identifier received by the content identifier reception unit into the format used in the client apparatus in accordance with a conversion routine stored in the storage in such a manner that the conversion routine is associated with the service identifier of the storage service provided by the server which has transmitted the content identifier; and a content identifier transmission unit that transmits the content identifier obtained through the conversion performed by the second conversion unit, as a response to the first request data received by the request data reception unit to the client apparatus. |
