This document specifies requirements for data storage, archiving, and data persistence of digital product passports, all based on a decentralized approach. The archiving functionality securely stores historical passport data, preserving a comprehensive record of past information. Persistence ensures that data included in the digital product passport remains available even when the economic operator creating the digital product passport is no longer active.
This document also specifies requirements for the replication between economic operators and back-up opera-tors as well as rules for data lifetime definition
