Note: There is a newer version of this specification see VEC 2.1.0

A UsageNode represents a position in an abstract vehicle. For example, the "Head Light Left". UsageNodes belong to the master data and they are defined on some companywide level. They can be used to enforce consistent naming over different projects and different development streams (e.g. between Geometry and Electrologic).

A UsageNode can be realized by different elements in the VEC (e.g. NetworkNode, OccurrenceOrUsage, TopologyNode, ComponentNode).

Name Type Mult. Description Owning Classifier
abbreviation LocalizedString 0..*

Specifies an abbreviation of the UsageNode. Normally this a human readable short name.

identification String 1

Specifies a unique identification of the UsageNode. The identification is guaranteed to be unique within the context. For all VEC-documents a UsageNode-instance can be trusted to be the same if the context-instance is the same and the identification of the UsageNode is the same.

description AbstractLocalizedString 0..*

Specifies additional, human readable information about the UsageNode.

usageNodeType UsageNodeType 0..1

Defines the type of the UsageNode. The type determines how the UsageNode is handled in the latter processes.
