The Open University and the Lucero project have recently launched data.open.ac.uk, an RDF repository of metadata from Open University datasets, such as podcasts, courses, and more. The metadata from these datasets are interlinked and accessible through SPARQL queries.
Needless to say, this initiative provides excellent opportunities for harvesting previously disconnected datasets and providing new services to Open University learners. So, I’ve reused some code kindly provided by Fouad Zablith, in order to produce a widget for the ROLE project. The widget has been built as a Moodle block for recommending learning material inside OpenLearn courses. The widget queries data.open.ac.uk and displays a list of Open University courses, iTunesU podcasts, as well as OpenLearn tags related to the course that the user is currently viewing. You can try it out by logging in as guest at PlaySpace.
