The EIRA© Highlevel viewpoint models an introductory overview of the focal Architecture Building Blocks of each view. 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. The EIRA© with its views provides a set of Architecture Building Blocks, important to facilitate interoperability. Each view, one for each interoperability level, is represented with the Focal Architecture Building Blocks needed to deliver an interoperable solution. These focal Architecture Building Blocks are indicated with an accented colour. In the high-level are represented the ABBs that link the EIRA©’s views enabling navigation between the different views. As such they should be considered as critical components of any interoperable public service. They are not necessarily mandatory but should always be considered by a user of the EIRA© when executing one of its use cases. Narrative: This viewpoint selects Architecture Building Blocks from the five different views highlighting the focal building blocks of the EIRA©: 1. The selected Architecture Building Block of the legal view shows the [Public Policy] is realised by [Legal Act] and [Digital Public Service]; these two ABB, referred to the legal view, are aggregated within the [Shared Legal framework]. [Shared legal Framework] influences [Organisational Functional Content], [Semantic Functional Content], [Technical Application Functional Content]. 2. The selected Architecture Building Blocks of the organizational view show a [Shared Governance Framework] that aggregates the [Organizational Functional Content] which considers a [Digital Public Service] which can be an aggregation of other [Digital Public Service]. The [Digital Public Service] realises a [Digital Business Capability]. A [Digital Business Capability] describes key functions supporting the [Digital Public Service]. A [Digital Public Service] accesses [Information], which can be an aggregation of other [Information]. At the same time a [Digital Public Service] is assigned by a [Digital Public Service Delivery] which is connected through a serving relation with the [Digital Public Service Delivery Model]. 3. The selected Architecture Building Blocks of the semantic view shows the [Shared Knowledge Base] and that the [Semantic Functional Content] is composed of a [Representation], stored as [Data] and the [Ontology]. 4. The selected Architecture Building Blocks of the technical views - application shows that a [Interoperable Digital Solution Service] is composed of a [Digital Solution Service] realized by a [Digital Solution Component] and lets consumers access it via [Machine to Machine Interface] and/or [Human Interface], which are part of a [Application Presentation and Access Enablers]. A [Digital Solution] exposes one or more [Digital Solution Service] via its [Machine to Machine Interface] and/or [Human Interface]. The [Digital Solution] uses [Digital Service Infrastructure] which uses a [Computing Hosting, Networking, and Data Hosting Infrastructure]. 5. The selected Architecture Building Blocks of the technical views - infrastructure considers the [Computing Hosting, Networking and Data Hosting Infrastructure].
