We spend our time trying to make (potential) students know about us through website… surely there is a better way
We keep cataloguing things in different systems and models - We really should be better at exploiting our own data assets

Semantic Technologies
Are about data and knowledge representations to make them interpretable and usable by machines, across the web.

Share Data Develop with Data Create Apps with Data
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...
Thank you!
