Terminology Model Object Types

In order to define a terminology model, several concepts have to be defined, which can be assigned to different concept categories. The following topics will introduce different concept categories by explaining the meaning of these concept categories. In this chapter, precise definitions of concept categories are provided. Details of terminology model object types are described in "Terminology Model Reference".

In the previous chapter, the following relevant concept categories have been discovered:

• Object
• Class
• Object collection
• Object type
• Classification
• Category
• Aggregation type
• Behavior (rules)
• Causalities

Although objects are subject of terminology models, they will not directly play a role within the terminology model. Not the objects itself, but different ways of representing knowledge about objects are in focus of TM. In general, TM distinguishes between concepts relating to objects or part of it (items) and the features, an item concept provides.

TM defines a hierarchy of items and its features. Hence, this chapter mainly introduces categories for items and features.
