Subject Area Elements
HOPEX Information Architecture allows you to easily update your subject areas from already existing dictionary elements: Term, Concept, State Concept, Event Concept or Concept View.
The list of elements from a subject area is accessible from its properties dialog box in the
Characteristics,
Scope and
Scope instance sections.
A subject area is used to describe all the elements defining your information architecture:
• Concepts
An event concept represents an event occurring during concept life, for example a change of season. An event concept marks the impact on a concept of a phenomenon internal or external to the concept. Concept events can be distinguished as concept start events, end events and intermediate events.
• Concept variations
A variation describes how a concept can be varied under another form. The variant is an object similar to the varied object, but with properties or relationships that may differ.
• Concept types
A concept type enables classification of concepts. Relationships between concept types are represented by concept type components.
• State concepts
A state concept is a situation in a concept life cycle during which it satisfies certain conditions, executes a certain activity or waits for a concept event. A state concept represents a time interval of which limits are two concept events. A state concept is a phase through which the concept passes during its life cycle.
• Event concepts
An event concept represents an event occurring during concept life, for example a change of season. An event concept marks the impact on a concept of a phenomenon internal or external to the concept. Concept events can be distinguished as concept start events, end events and intermediate events.
• Individuals
An individual represents the occurrence of a concept.
• Individual states
An individual state is an instance of a concept state to which the dictionary state is connected. It represents an individual state during its life cycle.
A subject area can be completely or partially described by a concept graph.
