Database

OPCUA needs a database of standard nodes, they are provided by XML NodeSet files. To speedup the startup of the client and server, these files are preprocessed and stored as term files. The special directory priv/nodeset/Schema must contain the standard OPCUA node-set definition Opc.Ua.NodeSet2.Services.xml, the attributes mapping definition AttributeIds.csv and the status code mapping StatusCode.csv. The generated data files needed for runtime are stored in priv/nodeset/data.

The node-set can be extended by adding custom definitions in priv/nodeset/reference sub-directories as XXX.NodeSet2.xml files.

To update the node-set, you can use the provided script:

`scripts/update_nodeset.sh -v v1.04`

To only regenerate the internal data without updating the reference files: scripts/update_nodeset.sh refresh
