  65. 65. Conclusion 1- Build data infrastructures that are flexible and allow diversity 2- Data sharing enables data analytics 3- => Tackle complex issues in education through making rich data available, to learners, educators and developers, and without a priori judgement of value What’s the real goal? Supporting the whole lifecycle of learning - from decision to realisation. Systems that can answer queries of the form “I want become X, what should I do?” - This is a data problem...
