3.1 Terms and definitions

For the purposes of this document, the terms and definitions given in OPC 10000-1, OPC 10000-3, OPC 10000-4, OPC 10000-5, OPC 10000-6, OPC 10000-14, OPC 10000-19,OPC 10000-100,

OPC RIO, OPC PE and the following apply.

3.1.1 SerializationStartNode

an Object or Variable that is the root Node of the Node-tree containing the Serialization Scope.

Note 1 to entry: The SerializationStartNode is the SourceNode of the HasSerializationEntity ReferenceType.

Note 2 to entry: The SerializationStartNode can also be an ObjectType or VariableType to use the InstanceDeclaration mechanism when creating instances of these types.

3.1.2 SerializationEntity

the TargetNode of the HasSerializationEntity ReferenceType.

Note 1 to entry: The parent Object of the SerializedData Variable containing the SerializationValue and allows the configuration of the SerializationScope and the Serialization DataTypes.

3.1.3 SerializationScope

the subset of Nodes directly or indirectly referenced by the SerializationStartNode, selected by the SerializationConfiguration.

3.1.4 SerializationConfiguration

the set of Properties of the SerializationEntity influencing the SerializationProcess and the SerializationScope.

3.1.5 SerializationValue

the merged compact aggregation of the Values of all serialized Nodes belonging to the SerializationScope and is the Value of the SerializedData Variable.

3.1.6 SerializationFieldDataType

the DataType of a field of the SerializationFieldDataType or the SerializationValue DataType to represent a serialized Node inside the SerializationValue.

Note 1 to entry: The serialized Node is the Value or the structure following the rules defined in 6.4.

Note 2 to entry: The SerializationFieldDataType of a Node may be nested (this means it can contain fields which are Structures) and contain the SerializationFieldDataTypes of child Nodes. The SerializationFieldDataTypes are Structure DataTypes created by the Server.

3.1.7 SerializationProperties

Properties of the SerializationEntity which allow the configuration of the SerializationProcess and the SerializationScope.

3.1.8 SerializationProcess

the mapping of the SerializationValue from and to the Values in the SerializationScope.

Note 1 to entry: This can imply the creation or re-creation of the SerializationFieldDataType used for the SerializationValue.
