The present invention encapsulates content and provides the encapsulated content to a use. A capsule stores identification information in structure information in a metadata unit thereof, and identification information such as URL and URN is stored therein. A capsule engine unit decodes the identification information. In the case of URL, the capsule engine unit directly obtains the entity of data or programs constituting the content from a server, which is an external storage. In the case of URN, the capsule engine unit inquires URL to a dictionary server such as a metadata repository, and obtains the URL from the server. Therefore, it is not necessary to install the entity of data or programs in a data cache unit, and it is possible to easily deliver and distribute the capsule.
