5.1 Overview

The DPP regulations places the burden on Manufacturers to collect the information that needs to go into the DPPs for the products they produce. This requires the Manufacturer be able to retrieve the DPPs for the materials, understand the information in them, and build their own DPPs that have the information required by regulation including links to the DPPs of additional product components. OPC UA provides an information modelling framework that can describe the requirements of the various regulations and allow a Manufacturer build its own DPPs using existing tools. The OPC UA information models are also used by the existing OT systems which data management needs.

The UACloudLibrary is a key part of the OPC ecosystem, and it is a cloud-based repository for OPC UA information models. Multiple versions of the UACloudLibrary are deployed in production systems today. This makes UACloudLibrary a foundation for a DPP Service Provider that provides additional services to Manufacturers to help them create and maintain their DPPs.

The relationships between the UACloudLibrary and the various actors involved with DPP creation and consumption are shown in Figure 8.
