Building the Open Universitys Web of Linked Datahttp://lucero-project.info Mathieu dAquin

Linked DataAs set of principles and technologies for a Web of DataPutting the raw data online in a standard representation (RDF)Make the data Web addressable (URIs)Link with to other Data Linked Data

ApplicationsPlan for development of specific applications targeting:Students: in finding resources related to courses, topics, and helping selecting courses to enroll toResearchers: Identify interesting connections/research questions from research data linked to OU/external sourcesAlready a number of (more generic) applications emerging

Faceted BrowsingSocial Learn

SocialLearn(Recommendation)NextMore data, more data, more dataInfo about buildings (estate), course material (Library), open educational content (OpenLearn), People (AACS/IT), Anything else?Links, Links, LinksInternal links based on common URI SchemeCurrent experiments on linking people, conferences, journalsAutomatic discovery of links Applications, Applications, ApplicationsA killer app (SocialLearn? Research Data?)Many, many small usages (publication and courses in people profiles, related material in course pages, annotation, etc.)Anything KMi can come up with!?

Conclusion[data.open.ac.uk] is the first launched of its kind in UK Universitieshopefully this is the first of many data.foo.ac.uk to come!if you are working in an IT department within a University you better read this report, as soon your department will need to be making these same decisions. David Flanders, JISCExpo Programme Manager,http://code.google.com/p/jiscexpo/wiki/luceroproject#Site_Visit_Report

Conclusion We believe linked open data to be essential to the OU, so it needs support:To ensure a sustainable framework to expose, maintain, update and evolve Open Linked University DataTo adopt the practices of exposing data a common, reusable, open way through data.open.ac.ukTo develop the applications that will show the benefit of the technologyThanks!
