5.4 Manufacturer needs to Build a DPP for a new Product

The Manufacturer uses a standard OPC UA Modelling Tool to build a DPP which contains the required DataElements. They enter the information as values of the Variables and saves it as a DPP in the UACloudLibrary. The format of the DPP in this context is a NodeSet, to ensure compatibility with tools currently used in factories.

If the Manufacturer needs to produce DPPs with Batch or Item granularity, they can create a new subtype of DigitalProductPassportType that is instantiated by their OT systems during production. The OT systems would then automatically publish DPPs to the UACloudLibrary using UACloudLibrary APIs.

The Manufacturer also has the option of specifying the RolePermissions for any DataElement which allows the Manufacturer to control who has access to information. When a Consumer requests a DPP, it provides credentials that are mapped to Roles.
