This ABB is salient for organizational interoperability by establishing the business principles to exchange data between public services. The Interoperability specification ABB is salient for semantic interoperability too in terms of identifying technical standards for the exchange of information between public services. And finally, the ABB is salient for technical interoperability due to it determines the technical requirements to implement the interoperability between public services.
