        • Involved in Web work since January 1993
        • Focus on Web technologies and not e-learning!
      • About UKOLN:
        • National centre of expertise in digital information management
        • Based at the University of Bath
        • Funded by MLA and JISC to support the cultural heritage and higher/further education sectors
      Introduction
    • About This Introduction
      • Your context:
        • You’ve explored interesting e-learning issues in your project, including pedagogical & technical aspects
        • We’ll hear from several projects
      • Are you still relevant? Has Web 2.0:
        • Changed the rules
        • Changed users’ behaviours and expectations?
        • Redefined who the various service providers are?
      • And do we (as academic, developers, managers…):
        • Need to fund development work differently?
        • Need to deploy services differently?
        • Need to revisit our relevance?
      Introduction
    • 1 Web 2.0 As Platform
      • Web 2.0 is the platform for doing things
        • Technical infrastructure now available (RSS, REST, URIs,…)
        • It’s in place now
        • It was designed (since 1990) to be global, scalable, … (Web 2.0 was Sir Tim’s original vision)
      • What’s the future for the application?
        • Google (and others) threatening MS
      Assertions Web 2.0 will bring about the demise (radical transformation?) of the monolithic VLE – and the open source VLE
    • 2 Global Social Networks
      • Web 2.0 made us aware of benefits of social networks (why did we miss it?):
        • Things that get better as numbers grow (Google link analysis algorithm)
        • Our social nature
        • Our diversity of social networks: school, work, play, professional, …
        • Experiences from Facebook (connections from school)
      Assertions Social networking systems need a critical mass, Global is good; is a class, a department or a university too small?
    • 3 “Embrace Constraints”
      • Traditional public sector IT development:
        • Standards defined (technical, accessibility, legal, …)
        • Technical architecture defined (fully interoperable with everything and use the latest TLA standards)
        • Well-funded programme call
        • Two/three year funded projects
        • Formal advisory groups, reporting structures, …
      • Results in:
        • Driving out innovation
        • Flawed services arriving too late
      Assertions Let’s agree to ‘embrace constraints’ and provide a useful service quickly (cf Basecamp)
    • 4 Cost Effectiveness
      • Challenge public sector norms:
        • Must be universally accessible
        • Must work on all platforms
        • Must work on legacy systems
        • Must be managed in-house
      • Tell me:
        • Why?
        • Does the best drive out the good?
        • Don’t you encounter the ‘IT Services barrier’ (Skype is evil, doesn’t use the right standards,…)
      Assertions Have you costed Amazon S3 and EC2 (e.g. 2-click installation of Moodle for $9/month)?
    • 5 Live (slightly) Dangerously
      • Can’t use social networks:
        • Data protection, privacy, …
        • Need to protect students from embarrassing themselves
        • It’s not what IT should be used for
        • It’s not what university is about
        • You’ll catch viruses
        • You’ll meet the wrong type of people
        • The data isn’t preserved
        • The data is preserved
      Assertions Make IT blended; part of University life. It’s like student bars, accommodation, parties, …
    • 6 Addressing Your Concerns
      • But what about:
        • Risks of using 3 rd party services
        • Sustainability
        • Quality assurance
        • Assessment
        • Changes to political, cultural & economic framework
      Assertions “ Events, dear boy, events!” That’s life, and we’ve been though it before.
    • Summary
      • What if:
        • The VLE is dying?
        • Flickr & Facebook define students expectations for social networks?
        • The lightweight stuff wins over the masses; the slow-moving worthy stuff doesn’t get used?
        • Out-sourcing the infrastructure delivers benefits to the institution (cost-savings) and users (richer functionality (cf. TCD and Google Mail)
        • Web 2.0 today is like student life in 1960s
        • Everything I have said is completely wrong!
      Will your project fit in with a changed environment? Will it have the flexibility to respond to possible changes?
    • Questions
      • Any questions?
