Notes:
The typical approach to storing meta information about a particular object is to use the classification system. The meta information of a class object can be used by the system to create an object called an instance. The concept of a class evolved based on experience. By definition, an object provides a well defined interface to its consumer and hides its complexity. It should also provide for the organization of methods and properties, eliminating dangerous situations where methods can be executed inadvertently. Consequently, EsiObjects classes support multiple interfaces. In addition to meta level data needed to create object instances, classes also support documentation objects, class variables, etc.
