For the purposes of this document, the terms and definitions given in OPC 10000-1 and the following apply.

a widely applicable feature or feature-set represented by an ObjectType that will be applied using aggregation

instance of a DataType Node that is used together with the ValueRank Attribute to define the data type of a Variable

a fundamental building block DataType defined by this standard

Note 1 to entry: The list of Built-in DataTypes and their encodings are defined in OPC 10000-6.

a DataType which is not a Structure, Enumeration or OptionSet

Note 1 to entry: See 5.8.2 for additional information.

NodeId of a DataType Node

refinement of a Structured DataType restricting the usage of fields and adding meta data to fields

Variables that represent values of Objects, either directly or indirectly for complex Variables, where the Variables are always the TargetNode of a HasComponent Reference

ObjectType Node that represents the type definition of an Event

Reference that is used to construct hierarchies in the AddressSpace

Note 1 to entry: All hierarchical ReferenceTypes are derived from HierarchicalReferences.

Node that is used by a complex TypeDefinitionNode to expose its complex structure

Note 1 to entry: This is an instance used by a type definition.

an abstract ObjectType used to specify a feature or feature-set that shall be implemented by the Object or ObjectType where it is applied to

metadata of an InstanceDeclaration that defines how the InstanceDeclaration will be used for instantiation and also defines subtyping rules for an InstanceDeclaration

Variables that are the TargetNode for a HasProperty Reference

Note 1 to entry: Properties describe the characteristics of a Node.

Node having a Reference to another Node

EXAMPLE: In the Reference “A contains B”, “A” is the SourceNode.

restriction of the usage of a subtype of a DataType to only allow a subset of all its subtypes

Node that is referenced by another Node

EXAMPLE: In the Reference “A contains B”, “B” is the TargetNode.

Node that is used to define the type of another Node

Note 1 to entry: ObjectType and VariableType Nodes are TypeDefinitionNodes.

Node that represents the type definition for a Variable
