  • Examples of Fundamental principles: O ne stop shopping : Organisations in the public domain preferably provide their services/products as a logical set/bundle, related to the event on the user side (birth, marriage, starting a business), and to be able to do so, cooperate with other organisations in the public domain Transparent, traceable service processes: Organizations in the public domain provide citizens, companies and public organizations with immediate access to the status of their service processes. Examples of derived principles: Messages & data: Data and proces-specific communication standards should contain a semantic model or refer to such a model. Information exchange: Exchange between sectoral service buses is always realised through the Public Sector Service Bus.

  • Services-approach es in Dutch Higher Education E xpectations, opportunities and current activities 09/23/10
  • Services ……..
    • Relatively small software components
    • Each component provides a unique functionality
    • These can be linked to support more complex work processes
    • Standardise on the messages, allowing diverse technical implementations
    Expectations, opportunities and current activities
  • Service Orientation: the expectations
    • For the user (students and staff):
      • Increased user-friendliness and transparency
      • Demand-driven instead of supply-driven information function
    • For the ICT department:
      • Standardise interfacing between system components (integration)
      • Leading principle for (shared) information architecture development
    • For management
      • May lead towards shared services centres
    Expectations, opportunities and current activities
  • HEI services adoption in the Netherlands
    • Closely linked to IT governance and ‘working under architecture’
    • Services approach as a leading principle in reference architectures
    • Practical work often in reaction to disappointing portal projects
    • Main drivers:
      • application integration
      • reduction of duplicate functional components
    Expectations, opportunities and current activities
  • Some sectoral initiatives
    • Services approach to integrate existing institutional e-learning infrastructures: 3TU Graduate School
    • SIS User Group taking the lead in making their application service-enabled: Osiris
    • Joint SIS requirements specification & selection on the basis of services definitions: SaNS
    Expectations, opportunities and current activities
  • National level framework: NORA
    • Dutch Public Sector Reference Architecture
    • part of ‘e-government’ strategy
    • functional perspective: ‘client first’
    • technical perspective: semantic - and s ervice oriented
    • Defined at 3 architectural layers:
      • Business architecture
      • Information architecture
      • Technical architecture
    • 20 ‘fundamental principles’ + 140 derived principles:
      • Interoperability principles (mandatory)
      • Internal principles (advised)
      • De jure principles
    • Now working on sector instantiations
    Expectations, opportunities and current activities
  • National methods and tooling
    • Service oriented architecture modelling language: Archimate
    • Archimate-approved tools: BiZZdesign and ARIS
    • But:
      • Limited adoption
      • Various ‘local modelling dialects’
      • No shared underlying semantic models
    Expectations, opportunities and current activities
  • SURF activities
    • Developing SOA building blocks
      • Federated identity management: A-select
      • National integration: StudieLink – ‘almost soa’
      • Federated educational and research repositories: LOREnet and DAREnet
    • Promoting cooperation and dissemination
      • Architects community
      • Archimate partnership
      • Cheap licences for archimate tooling
      • Support ‘business demonstrator’ projects
      • Plan to make outcomes widely and ‘standardised’ available for repurposing
    Expectations, opportunities and current activities
  • International cooper-ation
    • E-Framework
      • Partnership between UK-JISC; Australian D EST; New Zealand MoE; Dutch SURF foundation
      • Aim: “…harness the development and wide adoption of open standards and flexible infrastructures to support … education, administration, teaching and research.”
      • Products: Service Usage Models, Service Descriptions, and Core SUMS (pattern)
    • TENCompetence:
      • 4-year RTD project, EU-IST-TEL programme, 15 partners from 9 countries
      • Aim: Establish a technical and organisational infrastructure for lifelong competence development
    Expectations, opportunities and current activities
  • SOA reality in Dutch HEI
    • Most HEIs have entered the ‘awareness phase’
    • The ‘early adopters’ apply SOA to address operational problems, not so much for strategic purposes
    • ‘ service enabling’ of existing applications and ‘self services’ exposed through portals, but no full fledged SOA implementations yet
    • Cooperation for system replacement and selection – soa is one of the criteria
    • Sectoral initiatives towards interoperability and shared services ‘the next thing’?
    Expectations, opportunities and current activities
  • Present issues
    • Just-in-time and just-enough architecture
    • Convincing our own manage-ment is complex enough
    • Implement an institutional services architecture
    • Web2.0 means giving in to anarchy
    • …………………………………
    • Overall architectural design
    • Only cooperation leads to long term advantages
    • Work towards defining and implementing shared services
    • Web2.0 provides exiting new opportunities
    • ………………………………………
    Expectations, opportunities and current activities
  • So, what’s in it for students
    • Personalised electronic learning environment through a ‘plug and play’ architecture
    • Transparency in educational offerings, leading to more demand-driven education
    • Life-long personal services, spanning education, work, and private life
    Expectations, opportunities and current activities
    • But still a lot of work to do
    Expectations, opportunities and current activities
