Description​

The processDPP service is responsible for processing a Digital Product Passport (DPP), issuing a Verifiable Credential (VC), uploading it to the Storage service, and registering the link to the stored DPP with the Identity Resolver service. It handles the entire lifecycle of creating and managing a DPP, from data input to storage and resolution.
