Clause A.3 defines the numeric identifiers for all of the numeric NodeIds defined by the OPC UA Specification. The identifiers are specified in a CSV file with the following syntax:
<SymbolName>, <Identifier>, <NodeClass>
Where the SymbolName is either the BrowseName of a Type Node or the BrowsePath for an Instance Node that appears in the specification and the Identifier is numeric value for the NodeId.
The BrowsePath for an instance Node is constructed by appending the BrowseName of the instance Node to BrowseName for the containing instance or type. A ‘_’ character is used to separate each BrowseName in the path. For example, OPC 10000-5 defines the ServerType ObjectType Node which has the NamespaceArray Property. The SymbolName for the NamespaceArray InstanceDeclaration within the ServerType declaration is: ServerType_NamespaceArray. OPC 10000-5 also defines a standard instance of the ServerType ObjectType with the BrowseName ‘Server’. The BrowseName for the NamespaceArray Property of the standard Server Object is: Server_NamespaceArray.
The NamespaceUri for all NodeIds defined here is http://opcfoundation.org/UA/
