OPCFoundation.NetStandard.Opc.Ua.PubSub.Schema.Debug

OPC UA PubSub Schema

Runtime schema generation for OPC UA PubSub JSON message payloads. Produces JSON Schema (draft 2020-12) documents that describe the JSON DataSetMessage body for a writer from its DataSetMetaDataType metadata, so consumers (validators, code generators, documentation tooling) can be driven directly from the live PubSub configuration.

Part of the OPC UA .NET Standard stack (OPCFoundation.NetStandard.Opc.Ua.PubSub.Schema). Built on the core runtime schema subsystem (Opc.Ua.Core.Schema); no reflection, NativeAOT / trim safe.

Features

• Generates JSON Schema for the Part 14 PubSub JSON message mapping (Part 6 reversible / non-reversible encoding rules).
• Driven from runtime DataSetMetaDataType — schemas reflect the actual configured fields, data types and DataSetFieldContentMask.
• Resolves built-in and custom (structured / enumerated) data types through the encodeable type system.
• Dependency-injection first: services.AddOpcUa().AddPubSubSchema() registers IPubSubSchemaProvider; a direct-construction path (new PubSubSchemaProvider(...)) is also available.

Quick start

services.AddOpcUa().AddPubSubSchema();
// ...
var provider = serviceProvider.GetRequiredService<IPubSubSchemaProvider>();
IUaSchema schema = provider.CreateDataSetSchema(dataSetMetaData, fieldContentMask);
string jsonSchema = schema.ToSchemaString();
