The object of the present invention is to facilitate collection of contents that are present on a network.Attribute information is stored at a predetermined location under a domain in a server that provides a device driver. The attribute information specifies attributes of the driver provided by the server, such as the address, the corresponding type, the version, the installation method, and the platform, in an XML format. The user of the driver fetches the attribute information from a computer connecting with the network and analyzes the details of the attribute information, so as to readily specify the address of the driver, irrespective of the construction of the server. The attribute information also shows whether or not the driver has been updated. This arrangement facilitates automatic acquisition of the updated driver.
