1. A control system comprising a web server, an Aspect Object, an Aspect System Object and a software application, wherein the system executes a method comprising generating a web request for the function of the real world object with a world wide web presentation unit installed on a device, the web request comprising a Uniform Resource Locator comprising an identifier configured to identify the Aspect Object and the Aspect of the Aspect Object, the web request further comprising contextual information regarding the device and characteristics of the world wide web presentation unit, wherein the function comprises closing a valve, retrieving maintenance records of a motor, presenting a list of available suppliers, physical location, current stage in a process, a control function, an operator interaction, a simulation model, and documentation about the real-world object, transmitting the web request from the device through a network, receiving the web request in a web server of the control system, transmitting the web request to a software application unrelated to the world wide web presentation unit, identifying in the software application of the control system the Aspect Object and the Aspect by use of information in the Uniform Resource Locator, querying the identified Aspect Object from the software application for a reference to an interface to an Aspect System Object associated with the Aspect, receiving from the Aspect System Object to the software application the reference to the interface of the Aspect System Object, which implements the function of the identified Aspect, transmitting one of the contextual information or a reference to the contextual information about the world wide web presentation unit by the software application to the Aspect System Object, invoking functionality of the Aspect with the software application utilizing the reference to carry out the function of the real-world object, sending a response message from the web server to the world wide web presentation unit, wherein the response message is adapted to the contextual information, and updating the world wide web presentation unit with the result of the performed function of the real-world object.
