Building the Open University's Web of Linked Data
Download as PPTX, PDF2 likes835 views
The Open University is exposing its data as linked open data and integrating it using semantic web technologies. This includes data about courses, educational resources, research publications, podcasts, and more. The data is hosted at data.open.ac.uk and links to external datasets. Applications are being built that combine and explore this integrated data in new ways to benefit users, such as a mobile course explorer and tools to analyze research communities and impacts. Exposing university data as linked open data is gaining adoption in the UK and beyond.

- 34. Why is it important?The OU has been the first University to expose its data as linked data: http://data.open.ac.ukNow widely recognized as a critical step forward for the HE sector in the UK (and worldwide)Favor transparency and reuse of data, both externally and internallyReduces cost of dealing with our own public data: integration and reuse by design Enable both new kinds of applications, and to make the ones that are already feasible more cost effectiveMany other UK universities have now followed our example: Lincoln, Southampton, Edinburg, Oxford, …And others in other countries are setting up similar initiatives (Muenster, Loja, UPM, CNR…)
- 35. Where this is goingLinked data across universitiesMore and more UK and European university creating their linked data platform (following us!)Towards data.ac.uk?LinkedUniversities.org – providing common vocabularies and tools so that linked data from different universities can integrate Aggregation of video material from Open Educational RepositoriesMajor Challenge: Common/linked categorization scheme and tag spaceIntegration with Schema.org/LRMI
