The Semantic view is the view of the European Interoperability Reference Architecture for the Semantic interoperability layer of the European Interoperability Framework. It models the most salient Architecture Building Blocks that should be considered in order to support semantic interoperability of information exchanges between administrations, businesses and citizens.

Narrative

[Business Information] is realised by a [Representation] of [Data]. [Data] can be grouped in [Data Sets], which can be documented in [Data Set Catalogues]. [Master Data], [Transactional Data], [Reference Data], [Open Data], [Descriptive Metadata] and [Base are specialisations of [Data]. [Representation] and [Data] are influenced by [Data Policies], which are [Organisational Policies], which in turn are influenced by [Public Policies].

These different Architecture Building Blocks define the [Semantic content] and each of these Architecture Building Blocks can have any [Interoperability Specification] associated, of which the [Semantic Interoperability Specification] is a specialisation. The following [Semantic Interoperability Specifications] are identified: [Core Data Model] and [Data Entities] which are a specialisation of [Data Models], [Character Encoding Scheme], [Syntax Encoding Scheme], [Data Level Mapping], [Schema Level Mapping] or [Identifier Scheme].

Focal Architecture Building Blocks

• Representation (from ArchiMate Framework)
• Data policy (as a specialisation of Resource, a model element of the archimate-af Strategy elements)¹
• Data as a specialisation of Data Object
• Semantic Interoperability Specification specializing Interoperability Specification (specializing Business Object )

Other Architecture Building Blocks

• Data Set Catalogue
• Semantic Interoperability Agreement
• Data Model
• Data Entity
• Data Model
• Core Data Model
