IV Components

The ENVRI RM information viewpoint defines a configuration of information objects, the behaviour of those objects, the actions that operate on those objects, and a set of constraints that should always hold for actions applied on objects. The presentation of IV components are organised as follows:

• IV Information Objects: definition of a collection of information objects manipulated by the system.
• IV Information Action Types: definition of events that cause state changes of information objects.

The relationship between information objects and information actions is further refined in the following pages

• IV Information Object Instances: definition of how valid instances of information objects are modeled.   
• IV States: description of information object states and state transitions resulting from actions.
