OPC UA .NET Standard — Types

OPCFoundation.NetStandard.Opc.Ua.Types provides foundational OPC UA values such as NodeId, Variant, DataValue, ByteString and ArrayOf<T>, encoding and message-context infrastructure, and node-state base classes such as BaseObjectState, BaseVariableState and MethodState. Generated standard NodeSet model and state types are supplied by the dependent OPCFoundation.NetStandard.Opc.Ua.Core.Types package.

Overview

Reference this package for built-in values, encoding/context infrastructure or the dependency-light WoT conversion surface below. Use Opc.Ua.Core.Types when you also need the generated standard model types. Server and client libraries bring their required layers through package dependencies.

Captured metadata

StringTable.GetSnapshot(out long version) captures an independent mapping and its monotonic mutation Version in one observation. EncodeableFactory.Fork() retains independent registration maps. Internal reference, type-table and factory images allow publication owners to prepare isolated changes and reject stale captures; they do not introduce a public node-manager batch or retention API. Empty nodes do not allocate a reference image until mutation or owner capture.

WoT / NodeSet conversion

The package also exposes the dependency-light Opc.Ua.Wot conversion surface used by the WoT source generator and WoT Connectivity runtime. WotNodeSetConverter converts UANodeSet models to and from Thing Models / Thing Descriptions.

The default output is semantic-first: the converter omits uav:nodes when the readable vocabulary reconstructs equivalently and adds that complete structured projection only for source facts not yet expressible. No uav:nodeSet envelope is emitted when the structured path is complete. Configure WotNodeSetConverterOptions.PreservationMode as:

  • WhenRequired (default) — use the envelope only for a demonstrated unsupported/future construct;
  • Always — include an explicit byte-exact archival envelope;
  • Never — reject any conversion that cannot be proven without the envelope (recommended for conformance tests).

Unmapped WoT JSON-LD members are retained individually as pointer-addressed, digest-protected residue in standard NodeSet Extensions; mapped OPC UA facts are never duplicated there.

Typed-reference links also use NamespaceUri-qualified model names such as ua:HasOrderedComponent directly in rel, alongside a definitive uav:refId ExpandedNodeId when needed. These names improve model semantics without replacing ExpandedNodeIds for instance identity.
