  • 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 &amp; 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.

    2. 2. Services-approach es in Dutch Higher Education E xpectations, opportunities and current activities 09/23/10
    3. 3. Services …….. <ul><li>Relatively small software components </li></ul><ul><li>Each component provides a unique functionality </li></ul><ul><li>These can be linked to support more complex work processes </li></ul><ul><li>Standardise on the messages, allowing diverse technical implementations </li></ul>Expectations, opportunities and current activities
    4. 4. Service Orientation: the expectations <ul><li>For the user (students and staff): </li></ul><ul><ul><li>Increased user-friendliness and transparency </li></ul></ul><ul><ul><li>Demand-driven instead of supply-driven information function </li></ul></ul><ul><li>For the ICT department: </li></ul><ul><ul><li>Standardise interfacing between system components (integration) </li></ul></ul><ul><ul><li>Leading principle for (shared) information architecture development </li></ul></ul><ul><li>For management </li></ul><ul><ul><li>May lead towards shared services centres </li></ul></ul>Expectations, opportunities and current activities
    5. 5. HEI services adoption in the Netherlands <ul><li>Closely linked to IT governance and ‘working under architecture’ </li></ul><ul><li>Services approach as a leading principle in reference architectures </li></ul><ul><li>Practical work often in reaction to disappointing portal projects </li></ul><ul><li>Main drivers: </li></ul><ul><ul><li>application integration </li></ul></ul><ul><ul><li>reduction of duplicate functional components </li></ul></ul>Expectations, opportunities and current activities
    6. 6. Some sectoral initiatives <ul><li>Services approach to integrate existing institutional e-learning infrastructures: 3TU Graduate School </li></ul><ul><li>SIS User Group taking the lead in making their application service-enabled: Osiris </li></ul><ul><li>Joint SIS requirements specification & selection on the basis of services definitions: SaNS </li></ul>Expectations, opportunities and current activities
    7. 7. National level framework: NORA <ul><li>Dutch Public Sector Reference Architecture </li></ul><ul><li>part of ‘e-government’ strategy </li></ul><ul><li>functional perspective: ‘client first’ </li></ul><ul><li>technical perspective: semantic - and s ervice oriented </li></ul><ul><li>Defined at 3 architectural layers: </li></ul><ul><ul><li>Business architecture </li></ul></ul><ul><ul><li>Information architecture </li></ul></ul><ul><ul><li>Technical architecture </li></ul></ul><ul><li>20 ‘fundamental principles’ + 140 derived principles: </li></ul><ul><ul><li>Interoperability principles (mandatory) </li></ul></ul><ul><ul><li>Internal principles (advised) </li></ul></ul><ul><ul><li>De jure principles </li></ul></ul><ul><li>Now working on sector instantiations </li></ul>Expectations, opportunities and current activities
    8. 8. National methods and tooling <ul><li>Service oriented architecture modelling language: Archimate </li></ul><ul><li>Archimate-approved tools: BiZZdesign and ARIS </li></ul><ul><li>But: </li></ul><ul><ul><li>Limited adoption </li></ul></ul><ul><ul><li>Various ‘local modelling dialects’ </li></ul></ul><ul><ul><li>No shared underlying semantic models </li></ul></ul>Expectations, opportunities and current activities

SURF activities <ul><li>Developing SOA building blocks </li></ul><ul><ul><li>Federated identity management: A-select </li></ul></ul><ul><ul><li>National integration: StudieLink – ‘almost soa’ </li></ul></ul><ul><ul><li>Federated educational and research repositories: LOREnet and DAREnet </li></ul></ul><ul><li>Promoting cooperation and dissemination </li></ul><ul><ul><li>Architects community </li></ul></ul><ul><ul><li>Archimate partnership </li></ul></ul><ul><ul><li>Cheap licences for archimate tooling </li></ul></ul><ul><ul><li>Support ‘business demonstrator’ projects </li></ul></ul><ul><ul><li>Plan to make outcomes widely and ‘standardised’ available for repurposing </li></ul></ul>Expectations, opportunities and current activities
    10. 10. International cooper-ation <ul><li>E-Framework </li></ul><ul><ul><li>Partnership between UK-JISC; Australian D EST; New Zealand MoE; Dutch SURF foundation </li></ul></ul><ul><ul><li>Aim: “…harness the development and wide adoption of open standards and flexible infrastructures to support … education, administration, teaching and research.” </li></ul></ul><ul><ul><li>Products: Service Usage Models, Service Descriptions, and Core SUMS (pattern) </li></ul></ul><ul><li>TENCompetence: </li></ul><ul><ul><li>4-year RTD project, EU-IST-TEL programme, 15 partners from 9 countries </li></ul></ul><ul><ul><li>Aim: Establish a technical and organisational infrastructure for lifelong competence development </li></ul></ul>Expectations, opportunities and current activities
    11. 11. SOA reality in Dutch HEI <ul><li>Most HEIs have entered the ‘awareness phase’ </li></ul><ul><li>The ‘early adopters’ apply SOA to address operational problems, not so much for strategic purposes </li></ul><ul><li>‘ service enabling’ of existing applications and ‘self services’ exposed through portals, but no full fledged SOA implementations yet </li></ul><ul><li>Cooperation for system replacement and selection – soa is one of the criteria </li></ul><ul><li>Sectoral initiatives towards interoperability and shared services ‘the next thing’? </li></ul>Expectations, opportunities and current activities
    12. 12. Present issues <ul><li>Just-in-time and just-enough architecture </li></ul><ul><li>Convincing our own manage-ment is complex enough </li></ul><ul><li>Implement an institutional services architecture </li></ul><ul><li>Web2.0 means giving in to anarchy </li></ul><ul><li>………………………………… </li></ul><ul><li>Overall architectural design </li></ul><ul><li>Only cooperation leads to long term advantages </li></ul><ul><li>Work towards defining and implementing shared services </li></ul><ul><li>Web2.0 provides exiting new opportunities </li></ul><ul><li>……………………………………… </li></ul>Expectations, opportunities and current activities

So, what’s in it for students <ul><li>Personalised electronic learning environment through a ‘plug and play’ architecture </li></ul><ul><li>Transparency in educational offerings, leading to more demand-driven education </li></ul><ul><li>Life-long personal services, spanning education, work, and private life </li></ul>Expectations, opportunities and current activities
    14. 14. <ul><li>But still a lot of work to do </li></ul>Expectations, opportunities and current activities
