## A.1 Namespace and identifiers for DEXPI Information Model

This appendix defines the numeric identifiers for all of the numeric NodeIds defined in this 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 the numeric value for the NodeId.

The BrowsePath for an Instance Node is constructed by appending the BrowseName of the instance Node to the BrowseName for the containing instance or type. An underscore character is used to separate each BrowseName in the path. Let’s take for example, the PlateAndShellHeatExchangerType ObjectType Node which has the DesignHeatFlowRate Property. The Name for the DesignHeatFlowRate InstanceDeclaration within the PlateAndShellHeatExchangerType declaration is: PlateAndShellHeatExchangerType_DesignHeatFlowRate.

The NamespaceUri for all NodeIds defined here is http://opcfoundation.org/UA/DEXPI/
