Unified Architecture Core - UA REST subgroup

The REST group, as a sub-group of the OPC Foundation UA Working Group, will discuss use cases for the integration of OPC UA via REST and propose potential extensions for the OPC UA specification. It is a special-purpose sub-group meant for IT (especially REST) experts and participants who work in Edge and Cloud computing areas to focus on discussion for these use cases.
SCOPE
The REST sub-group will discuss uses cases for OPC UA in Edge and Cloud computing environments using the proposed HTTP REST.
Non-exclusive examples for work items are:

• Generic REST interface definition for common OPC UA services (Read, Write, Call, …)
• Standardized mapping of OPC UA service parameters to datatypes commonly used in RESTful APIs
• How the existing session-less OPC UA service can be used with a REST interface.
• Define a concept to provide REST interfaces for Companion Specification use cases.
• Define requirements for security.
• Building prototypes and a demonstration.
• Define an OpenAPI-compatible REST interface using Swagger.
