The Technical view - infrastructure is a view of the European Interoperability Reference Architecture for the Technical interoperability layer of the European Interoperability Framework. It provides an architecture content metamodel for the most salient cross-sectorial infrastructure services, along with the supporting hosting and networking facilities, which shall be considered in order to support technical interoperability when building an Interoperable European Solution. The difference with the Technical view - application is that the Architecture Building Blocks in the infrastructure view are considered to be relevant for solutions in any sector of government.

The EIRA V3.0 Technical View - Infrastructure (simplified)


An [Interoperable European Solution] and its application components make use of cross-sectorial [Digital Service Infrastructures]. It provides access to data through [Infrastructure Data Source Enablers] such as [Forms Management Service], [Record Management Services], [e-Archiving Service], or [Metadata Management Service]. The [Data] can be archived using [e-Archiving Services] and published to external data sources with a [Data Publication Service]. [Collaboration Enablers] can exchange messages between [Interoperable European Solutions] using [Messaging Services] and exchange multimedia using [Audio-visual Services]. The [Application Services] provided by an [Interoperable European Solution] can be discovered by users or systems through [Discovery Enablers]. Privacy preservation is performed by the [Privacy Enablers]. The administration and operational management of an [Interoperable European Solution] is performed through [Administration Enablers]. Trust between systems is established with [Trust Service Provisioning Components] realised using Signature validation and verification such as [e-Signing Creation Service], [e-Signature Verification and Validation Service], [e-Signature Preservation Service], and through e-Seal services such as [e-Seal Creation Service], [e-Seal Verification and Validation Service], [e-Seal Preservation Service], and e-timestamping services such as [e-Timestamp Creation Service], [e-timestamp Verification and Validation Service]. Identity management is realised with [Identity Management Service]/[Identity Management Component]. Evidence of transaction between parties is realised using the [Registered Electronic Delivery Service]. The [Interoperable European Solution] can register its architecture, and application documentation using a [Configuration and Cartography service]. The [Interoperable European Solutions] and the [Digital Service Infrastructures] are deployed and operated through [Hosting and Networking Services Infrastructures], provided by a [Public / Private Hosting Facility], and make use of a [Public / Private Network] to exchange data.

The Architecture Building Blocks defined in both the [Digital Service Infrastructure] and the [Hosting and Network Service] can have any [Interoperability Specification] associated, of which the [Technical Interoperability Specification] is a specialisation. [Technical Interoperability Specification] is also a specialization of [Technical Specification].

Focal Architecture Building Blocks

Infrastructure enablers

To support the Digital Single Market in succeeding, the Connecting Europe Facility (CEF) programme is funding a set of generic and reusable Digital Service Infrastructures (DSI), also known as Building Blocks. The CEF Building Blocks offer basic capabilities that can be reused in any European project to facilitate the delivery of digital public services across borders and sectors. Currently, there are eight Building Blocks: Big Data Test Infrastructure, Context Broker, eArchiving, eDelivery, eID, eInvoicing, eSignature and eTranslation.
