TopologyNode
Note: There is a newer version of this specification see VEC 2.2.0
A TopologyNode is a point in the Topology where TopologySegments are starting and ending.

Attributes
| Name | Type | Mult. | Description | Owning Classifier |
|---|---|---|---|---|
| aliasId | AliasIdentification | 0..* | Specifies additional identifiers for the TopologyNode. Example: TopologyNode Ids may vary from one CAD system export to another. Therefore, the CAD system Id is improper for identification attribute. The identification shall have a value which is unique within the Topology. AliasId may be used for the CAD system Id. | TopologyNode |
| identification | String | 1 | Specifies a unique identification of the TopologyNode. The identification is guaranteed to be unique within the TopologySpecification. For all VEC-documents a TopologyNode-instance can be trusted to be the same if the TopologySpecification-instance is the same (see TopologySpecification) and the identification of the TopologyNode is the same. | TopologyNode |
| matchingPointId | String | 0..1 | Specifies an identifier that can be used for matching TopologyNodes that belong to different TopologySpecifications and are actually representing the same node. Example: There are two TopologySpecifications, each specifying the topology of a certain zone of the car. If the zones are adjacent, it is possible that there are TopologyNodes in both zones where the two topologies are connected / have contact. These "connection-nodes" would then define the same matchingPointId. | TopologyNode |
| processingInstruction | LocalizedString | 0..* | Specifies processing instructions for the TopologyNode. | TopologyNode |
| nodeType | NodeType | 0..1 | Specifies the type of the TopologyNode. A Node can either be an EndNode, a Junction or an Inliner. | TopologyNode |
