PDND Interoperability Infrastructure

The National Digital Data Platform (PDND), established under Article 50-ter of the Italian Digital Administration Code (CAD), is a core component of the national interoperability ecosystem. It provides the mechanisms for managing authentication, authorisation and logging of authorised entities, ensuring the security and integrity of information exchanges. The platform defines a set of shared rules aimed at streamlining interoperability agreements, reducing administrative burdens and simplifying procedural workflows. PDND also provides the API Catalogue, which lists all e-services published by public entities and through which data-access requests can be submitted and, subsequently, APIs can be integrated into services delivered to citizens. The overarching objective of the platform is to ensure full interoperability of datasets and key services across central and local public administrations, enabling the implementation of the once-only principle (public authorities must not request data already held by another administration) and fostering the * valorisation of the public sector’s information assets*. The platform offers several advantages to its users:

• • Providers*, who make their e-services available for data access, benefit from secure data exchange and standardised processes.
• Consumers can access the catalogue of available e-services and integrate APIs into their services for citizens and businesses.
• • Technical developers*, responsible for implementing and managing the lifecycle of an administration’s e-services, can rely on standardised integration models enabled by the platform.
• • Data Protection Officers* of participating entities can access standard administrative documentation and ensure a consistent and compliant process across all administrations.
• Business and citizens benefit from the implementation of the once-only principle, avoiding the need to resubmit information already provided to the public administration.
