  • 3. 1 SEMIC.EU Overview 3
  • 4. 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 EuropeSEMIC.EU was initiated in 2007 and it has been included as oneof the “larger” actions in the new ISA Programme (2010-2015) 4

  • 6. 2 SEMIC.EU Core Concepts and Core Vocabularies 6
  • 7. Core Concept – Vision Semantic definitions should be commonly agreedon fundamental, highly reusable concepts 7
  • 8. Core Concept – Challenges1 Is it possible for 27 MSs to agree on common semantics?2 Is it possible to define an entity (concept) in a way that remains relevant in different contexts? 8
  • 9. Core Concept - DefinitionA 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) 9
  • 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. 10

  • 12. Implementations and mappings? 15 12
  • 13. Core Concepts - Principles of development1.  Share ownership and involve the MSs2.  Identify 20-30 top reusable concepts e.g. Person, Vehicle, Building, Company, Project3.  Reuse existing vocabularies/definitions4.  Use a minimalistic approach Minimize the number of attributes, keep schemas simple.5.  Draft semantic documentation … to guarantee the proper reuse of a schema. 13
