OPCFoundation.NetStandard.Opc.Ua.XRegistry

Opc.Ua.XRegistry

The abstract xRegistry registry base model for OPC UA: a content-addressed resource-registry companion namespace plus the 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 and the *TypeClient ObjectType proxies. 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 content-derived identity (the fingerprint that makes a resource addressable by an Opaque NodeId, stable across registries).

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.
