A Business is an architectural building block of the EIRA Organisational view supporting the Organisational interoperability layer of the European Interoperability Framework.

Business is a specialisation of Business actor. It is employment, occupation, profession, or commercial activity engaged in for gain or livelihood. Activity or enterprise for gain, benefit, advantage or livelihood. Enterprise in which person engaged shows willingness to invest time and capital on future outcome.

The Business ABB is salient for organisation interoperability because organisations can play the role of consumers of Public Services (Public Administration or businesses), as stated in the EIF: "A European public service comprises any public sector service exposed to a cross-border dimension and supplied by public administrations, either to one another or to businesses and citizens in the Union."

Examples are plenty.
