Abstract

According to the present invention a method and a system is provided for organizing access and control from a user to an appliance via a distributed information system by employing a mediator. First a message is received from the user containing a generic command, which is then converted into an appliance specific command. Subsequently, the appliance specific command is sent to the appliance to be processed and a response message is received from the appliance. Finally, the response message is converted into a generic format and sent back to the user. The present invention provides an easy-to-use interface for users to all their pervasive home network devices.
