Interoperability by Design
‘Interoperability by design’ means that for a European public services to be interoperable, they should be designed with certain interoperability and reusability requirements in mind. The conceptual model promotes reusability as a driver for interoperability, recognising that European public services should reuse information and services that already exist and may be available from various sources inside or beyond the organisational boundaries of public administrations.
