1 SEMIC.EU Overview

SEMIC.EU – Scope
SEMIC.EU is a platform (www.semic.eu) and a set of services around this platform
to support semantic interoperability initiatives related to cross-border or cross-sector electronic interactions between Public
Administrations in Europe
SEMIC.EU was initiated in 2007 and it has been included as one of the “larger” actions in the new ISA Programme (2010-2015)

2 SEMIC.EU Core Concepts and Core Vocabularies
7
Core Concept – Vision
Semantic definitions should be commonly agreed
on fundamental, highly reusable concepts
8
Core Concept – Challenges
Is it possible to define an entity (concept) in a way that remains relevant in different contexts?
12
Is it possible for 27 MSs to agree on common semantics?
9
Core Concept - Definition
A Core Concept is a simplified data model that captures the minimal, global, generic, country and domain neutral characteristics/properties of an entity.
A Core Concept can be represented as Core Vocabulary
using various formalisms (e.g. XML, RDF)
10
Core Concept - Definition
• Definitions could first be agreed on fundamental concepts (Core), where diverged and/or conflicting views are less intense.
• A Core Concept/Vocabulary
Is highly reusable: the specification is simple and captures basic and generic characteristics of an information entity, regardless of the context this entity is used
Is extensible: domain specific specializations can be drafted on top of the core representation.

Core Concept – Core Person Extensions
Core Patient Core Voter Core Employee Core Student
Context Neutral
Context Specific

Implementations and mappings?

13
Core Concepts - Principles of development
1. Share ownership and involve the MSs
2. Identify 20-30 top reusable concepts e.g. Person, Vehicle, Building, Company, Project
3. Reuse existing vocabularies/definitions
4. Use a minimalistic approach Minimize the number of attributes, keep schemas simple.
5. Draft semantic documentation … to guarantee the proper reuse of a schema.
