Guidelines on Base Registries Interconnection

The Guidelines on Access to Base Registries Interconnection provide recommendations and good practice examples collected from Member States and EU Institutions, and guide users on how to overcome the challenges Member States face, as well as how to simplify the work on base registries (BR).

The Guidelines aim at complementing the Base Registries Access and Interconnection Framework (BRAIF) with more practical information on good practice examples and recommendations on how to overcome challenges that member states (MS) face, serving as guidance to MS on different aspects in the creation of base registries and registries of registries and on how to interconnect them. This document represents an update of the existing ABR Guidelines, which were published for the first time in 2020.

ABR Guidelines

Scope and target audience

This Guidelines document has the following objectives:

  • To discuss main aspects and challenges that may hinder the interconnection and interoperability of base registries at national and cross-border level;
  • To provide recommendations for the successful and sustainable development of base registries interconnections
  • To share good practice examples on solutions adopted across Member States for effective cross-border and cross-sector interoperability

The solutions and recommendations are of interest to Member States’ public administrations and their representatives, in particular, those roles that design strategies and policies, develop base registry data interconnection and interoperability models across public administration services.

Accordingly, these guidelines can be interesting for a variety of roles, but in particular for non-technical roles (Business and policy) which might be interested in having a full picture of base registries interconnectivity before discussing implementation plan with more technical roles. Such non-technical roles might include including staff of national and EU public administrations, such as:

  • Public Agents who are involved in both the interoperability and public services governance (including e-Government and legal experts);
  • Public Officers from the base registries and the roles responsible for the execution and monitoring of the processes needed for the exchange of data between stakeholders.
