1. A method to integrate an application in a computerized system for control of a real world object, which system comprises an Object Request Broker that provides access to said application through an interface, comprising the steps of:
- representing said real world object as a Composite Object, which contains an Aspect;
representing a facet of said real world object as the Aspect of the Composite Object;
associating said application with the Aspect by means of a first reference;
enabling a query to a Composite Object for a function associated with the Aspect;
obtaining through the Composite Object a second reference to the interface of said application which implements the function.

Abstract
A method of integrating an application in a computerized system for representing a real world object, and a system employing the method. The real world object may be any object, device, process or item of equipment, including equipment in industrial or commercial installation or process, in any location. The real world object is represented as an object, called a Composite Object, in a part of a computer program. The invention also includes Aspects which represent the data and/or operations of a Composite Object. The Composite Object is a container holding at least one Aspect representing data for the real world object. The Composite Object includes at least one interface for use by another object which interface is implemented by the Aspect System and accessed through an object Request Broker, that complies, for example, with COM. The principal advantage of the method and system is that applications within the system do not require prior information about other objects or applications included in the system. Modular and simplified expansion of the system is enabled, together with the later integration of applications not specified at the time of designing the system.
