The OPC Unified Architecture (OPC UA) is a protocol for Ethernet-based communication in industrial settings. At its core, OPC UA defines a set of services for interaction with a server-side information model that combines object-orientation with semantic technologies. So-called Companion Specifications use the OPC~UA meta-model to define domain-specific modelling concepts for semantic interoperability. open62541 is an open source implementation of the OPC UA standard. In this work, we describe the core concepts of OPC UA, how they reflect in the overall architecture chosen for open62541 and the measures taken to scale OPC UA to Big-Data operations.
