The EIRA© high-level viewpoint1 is a viewpoint of the European Interoperability Reference Architecture.

The Interoperability specification viewpoint models the most salient Architecture Building Blocks that shall be considered when providing interoperability specifications. It provides an overview of Architecture Building Blocks from the different views, and depicts them as a taxonomy of interoperability specifications. Each EIRA© view has Architecture Building Blocks that support interoperability.

Each view’s interoperability specifications serve to define the interoperability aspects of catalogues and registries, addressing both their contents and the respective catalogue or registry as a whole. Given the linked nature of the EIRA©’s views, the interoperability specifications from all views can be considered to affect each individual catalogue or registry. However, the focus in each case is kept within the specific view to best capture the level of detail that each view’s specifications deal with.
Narrative: An [ Interoperability Specification ] is a [Specification] and can be composed of other [Interoperability Specifications]. It exists at the four levels of interoperability defined in the European Interoperability Framework.

The EIRA Interoperability Specification viewpoint

This viewpoint selects Architecture Building Blocks from the five different views highlighting the interoperability specification related Architecture Building Blocks of the EIRA©:

Narrative

  1. The selected Architecture Building Blocks of the legal view shows that a [ Legal Interoperability Specification] defines the interoperability aspects associated to a [ Public Policy Implementation Approach ], and defines the interoperability aspects for a [ Legislation Catalogue ]. [Legal Interoperability Content]
  2. The selected Architecture Building Blocks of the Organisational view shows that an [ Organisational Interoperability Specification ] defines the interoperability aspects for [Governance Content] and [Operational Content]: an [ Interoperability Agreement ], a [ Public Service Catalogue ] and/or the [ Exchange of business information ].
  3. The selected Architecture Building Blocks of the semantic view shows that a [ Semantic Interoperability Specification ] defines the interoperability aspects for [ Data Set Catalogue ] as well as the interoperability aspects for [ Representations ]. [Semantic Content]
  4. The selected Architecture Building Blocks of the Technical view shows that a [ Interoperability Specification ] is a [Technical Specification], it defines the interoperability aspects for [ Interoperable Solution Service ] and [ Digital Service Infrastructure ] of a [ Machine to Machine interface ], a [Network] and/or a [ Service Registry Component] ]. The [Service Registry Component] provides a mechanism to register technical services within a catalogue to be discovered by others.
  5. The selected building block of the EIF Underlying Principle view show that [Interoperability Specifications] realise [ Interoperability Principles ], the general intended properties used to achieve interoperability. The interoperability Specifications can be used to define the interoperability aspects for any of the Architecture Building Blocks.
