Class

• <DRM Functional Association Data>

Superclass

• <DRM Base Association Data>

Subclass

• None.

Definition

An instance of this DRM class specifies the semantic meaning of the association relationship with which it is bound.

The meaning field specifies the semantic meaning of the association relationship.

Constraints

• Publishable object

Example(s)

• Let O be a <DRM Union Of Geometry Hierarchy> instance representing an overpass. O has:

  1. a <DRM Classification Data> component with tag = ECC_OVERPASS
  2. a <DRM Union Of Primitive Geometry> component S representing a bridge span within the overpass, where S has a <DRM Classification Data> component with tag = ECC_BRIDGE_SPAN
  3. a <DRM Geometry Model Instance> component P1 referencing M, with a <DRM World Transformation> component placing P1 on the right side of S
  4. a <DRM Geometry Model Instance> component P2 referencing M, with a <DRM World Transformation> component placing P2 on the left side of S

  To indicate clearly the functional relationship between the bridge piers and the bridge span within O, the data provider also supplies the following relationships:

  1. an association from S to P1 through a <DRM Functional Association Data> link object having meaning = SUPPORTED_BY
  2. an association from S to P2 through a <DRM Functional Association Data> link object having meaning = SUPPORTED_BY
  3. an association from P1 to S through a <DRM Functional Association Data> link object having meaning = SUPPORTS
  4. an association from P2 to S through a <DRM Functional Association Data> link object having meaning = SUPPORTS
