Feature types
Define the structure of real-world representations. A feature type lists the
attributes,
operations or
associations to other features
(collectively called “properties”
or “characteristics”) that a feature can have.
Feature instances (often called only Features)
Hold the content (or values) that describe one specific real-world object.
Simple features
Are instances of a feature type with no association to other features, and where all attributes
are constrained to the [1 … 1] cardinality. Such simple features are very common.
