DEFINITION: EIRA viewpoint ABB is a Business Object providing a perspective with specific stakeholders concern in mind. The EIRA© provides several viewpoints that conform to EIRA© views (1) A specification of the conventions for a particular kind of architecture view. Source: TOGAF (https://pubs.opengroup.org/architecture/togaf9-doc/arch/chap03.html#tag_03_18) EXAMPLES: The following implementation is an example on how this specific Architecture Building Block (ABB) can be instantiated as a Solution Building Block (SBB): Highlevel viewpoint The EIRA© Highlevel viewpoint models an introductory overview of the focal Architecture Building Blocks of each view. It aligns the EIRA© with the service delivery model described within the Interoperability Maturity Model (IMM), and the New European Interoperability Framework (EIF) conceptual model for public services. The ABBs included in the high-level viewpoint represent the points that link the EIRA©’s views enabling traceability between their different Architecture Building Blocks. They are not necessarily mandatory but should always be considered by a user of the EIRA© when executing one of its use cases.
