Have a look at this page providing extensive information on the the key concepts and benefits of the EIRA©. This page consists of the following sections:

• Chapter 1 provides an overview of the EIRA©.
• Chapter 2 provides further insights into several key concepts related to the EIRA©. 
• Chapter 3 provides an overview of the EIRA© views, viewpoints and its Architecture Building Blocks.
• Chapter 4 contains a glossary of the EIRA© referenceable terms/ABBs.
• Chapter 5 contains references.

This page is not meant to provide guidelines on how to use EIRA©. 

A Solution Architecture Template (SAT) is a specification extending the EIRA©. It provides support to solution architects in a specific solution domain. The SATs' purpose is to provide guidance by defining a minimal, but holistic (legal, organisational, semantic and technical) interoperability architecture to develop an interoperable solution. 

The following documents are available to help the architect in documenting a SAT:

• Detailed-level Interoperability Requirements Solution Architecture Template (DL SAT) Design Guidelines. 
• High-level Interoperability Requirements Solution Architecture Template (HL SAT) Design Guidelines for documenting the High-Level Interoperability Requirements for a solution using a Solution Architecture Template. 
• SAT Template in Word format to create a new SAT.

The following DL SATs have been published to date: 

• VAT scheme for SMEs v.1.0.1:  Enterprise and Solution architects can use the SAT model to finalize it and build their own national solution.
• Open Data SAT v1.0.1 Beta: Enterprise and Solution architects can use this document to design solution architectures in the domain of Open Data.
• eHI (Human Interface) SAT v1.0.1: Enterprise and Solution architects can use this document and the related SAT model to design solution architectures that have a Human Interface (as opposed to a machine-to-machine interface) as part of the solution. The proposed solution architecture template is EC centric.
• eDelivery SAT v1.0.1: Enterprise and Solution architects can use this document to design solution architectures in the domain of eDelivery.
• eID SAT v1.0.1: Enterprise and Solution architects can use this document to design solution architectures in the domain of eID cross border authenticated service.
• Interoperability Testing SAT v1.0.0: Enterprise and Solution architects can use this document when defining the architecture of their solution in order to introduce a platform to support interoperability and conformance testing. This assumes that the solution in question is required to foresee a well-defined means to enable such testing for its user community.
• e-Procurment: Enterprise and Solution architects can use this document to design solution architectures in the domain of e-Procurement. This SAT is to provides guidance by defining core legal, organisational, semantic and technical interoperability architecture in the domain of e-Procurement, and should allow businesses, citizens and public administrations to have a common understanding of the most-salient building blocks.
• CoS: Enterprise and Solution architects can use the SAT model to design solution architectures in the domain of Public Catalogue of Services.

The EIRA© Ontology is the machine-readable knowledge representation of EIRA© including classes and axioms, which provide stakeholders of different backgrounds – including technical and business – with the capabilities to search for, access to and analyse the EIRA© concepts. 

An Ontology is a formal description of knowledge as a set of concepts within a domain, whereas the axioms connect concepts and allow for logic inferences. An ontology is composed of the the terminological component (T-Box), assertions component (A-Box) and the rules for logic inference (i.e. the semantics).
