  • http:// www.opendefinition.org/okd / http://www.opengovdata.org/home/8principles The license must not restrict anyone from making use of the work in a specific field of endeavor. For example, it may not restrict the work from being used in a business, or from being used for genetic research. Comment: The major intention of this clause is to prohibit license traps that prevent open source from being used commercially. We want commercial users to join our community, not feel excluded from it.
  • The main event of the EU/SICoP supported by a dedicated website (part of the ISA platform) could be an annual conference where a) all MSs present their experiences with semantic IOP, b) areas for promoting cross-border semantic IOP are identified, c) NIFs alliance in semantic IOP is discussed.

Peristeras_Vassilios_Towards_Linked_Government_Metadata Peristeras_Vassilios_Towards_Linked_Government_Metadata Presentation Transcript

  • SEMIC.EU: Towards Linked Government Metadata Vassilios Peristeras EC, DG DIGIT, ISA Unit [email_address]
    • SEMIC.EU overview
    • Core Concepts and Core Vocabularies
    • Linked Government Metadata
  • 1 SEMIC.EU Overview
  • SEMIC.EU – Scope SEMIC.EU is a platform (www.semic.eu) and a set of services around this platform to promote semantic interoperability in EU Member States SEMIC.EU was initiated in 2007 and it has been included as one of the “larger” actions in the new ISA Programme (2010-2015)
  • SEMIC.EU – Scope Interoperability Assets 14 April 2011 Community building Taxonomies Code lists Methods and Concepts Guidelines and Studies Coaching & Community building Governance and Clearing Process Communication Management SEMIC.EU Platform Administration Coordination and Project Management Stakeholder Involvement Yearly Conference SEMIC.EU Road Show Platform Extension
  • Achievements of SEMIC.EU > 1.200 Users > 80 Projects Communities >500 Assets Visible in Europe Partner for eGovernment Quality Centre Semantic interoperability Knowledge base for semantics Sustainable Service for eGovernment
    • SEMIC.EU next steps:
    • To enable access to national repositories of semantic assets from a single point (federation)
    • To identify a small set of Core Concepts (e.g. 20-30) to be developed through the harmonization of existing assets and with the involvement of MSs
    • Create an EU Semantic Interoperability Community of Practice (EU/SICoP) where MSs representatives discuss issues and share experiences in semantic interoperability
    SEMIC.EU future directions (2011-2015)
  • 2 SEMIC.EU Core Concepts and Core Vocabularies
  • Core Concept – Vision Semantic definitions should be commonly agreed on fundamental, highly reusable concepts
  • Core Concept – Challenges Is it possible to define an entity (concept) in a way that remains relevant in different contexts? Is it possible for 27 MSs to agree on common semantics?
  • 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)
  • 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 – The Core Person Example Core Vocabulary
    • Identification of a person in eGovernment context
    • Based on the evaluation of 4 assets (Person models of Austria, Denmark, France and Germany)
  • Core Concept – Core Person Instantiations Core Patient Core Voter Core Employee Core Student
  • CorePerson – Initial Implementations
  • Implementations and mappings 15
  • Core Concepts - Principles of development
    • Share ownership and involve the MSs
    • Identify 20-30 top reusable concepts e.g. Person, Vehicle, Building, Company, Project
    • Reuse existing vocabularies/definitions
    • Use a minimalistic approach Minimize the number of attributes, keep schemas simple.
    • Draft semantic documentation … to guarantee the proper reuse of a schema.
  • 3 SEMIC.EU Linked Government Metadata
  • Linked eGovernment Metadata
    • Core Concepts as Linked eGovernment Metadata
    • provide the core concepts as metadata schemas in open formats (e.g. xml, csv) including rdfs
    • b) link and reuse terms from existing rdf vocabularies
    • c) provide URIs for the new terms introduced
  • Linked eGovernment Metadata Repository XML JSON RDF UML CSV Linked Government Metadata Repository Person Company Vehicle Project Building Address
  • Draft Time Plan Q2/2011 Q3/2011 Q4/2011 Q1/2012 Identification of Core Concepts Core Concepts Development and Review Vocabularies development Vocabulary Platform Implementation Q2/2012
