This document specifies requirements for decentralized data storage, archiving and data persistence of digital product passports. The archiving service securely stores historical passport data, preserving a comprehensive record of past information. This feature is particularly relevant for market surveillance purposes. Persistence is required to make sure that data included in the digital product passports remains available even when the economic operator creating the digital product passport is no longer active.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 operators as well as rules for data lifetime definition.
