OPCFoundation.NetStandard.Opc.Ua.XRegistry

Opc.Ua.XRegistry

The abstract xRegistry registry base model for OPC UA: structurally identified registry entities, an independent content-addressed document fast path, and shared abstractions a concrete registry (for example a schema registry) builds on.

This package contains:

• the http://opcfoundation.org/UA/xRegistry/ abstract base companion model, compiled into the assembly by the OPC UA model source generator — the ObjectTypes, their Methods and Variables, the generated NodeState classes, *TypeClient ObjectType proxies, and the xRegistry 0.5.0 *EventTypeRecord / EventFilters client surface. No NodeSet2 XML is parsed at runtime;
• XRegistryWellKnown — the base companion namespace URI and the provisional NodeIds of the instances a registry materializes at runtime (the registry root, the federation proxy and the start of the dynamic instance range). The identifiers of the model itself come from the generated ObjectTypeIds, MethodIds and VariableIds classes;
• IResourceContentIdProvider — the seam that maps a resource document + format to its opaque content key. The key makes document bytes addressable by an Opaque NodeId but never replaces the entity's structural Xid, ResourceId, or VersionId.

It has no dependency on the OPC UA server or client SDKs; the generic client and server pieces live in Opc.Ua.XRegistry.Client and Opc.Ua.XRegistry.Server.
