The JSON encoding defined in part 6 has been modified after feedback from SDK vendors since OpcUaJsonEncoder and OpcUaJsonDecoder were implemented.

Instead of "reversible" and "non-reversible" encodings there is now "verbose" and "compact". Where applicable, the "verbose" encoding eschews numeric references for which the receiving application might not have context and includes symbolic names and URIs when possible.

The types for which the encoding has changed include:

  • NodeId
  • ExpandedNodeId
  • QualifiedName
  • StatusCode
  • Matrix (multi-dimension array)
  • LocalizedText (always encoded as JSON object)
  • ExtensionObject (always encoded as JSON object)
  • Variant (always "verbose")
