The document discusses the Open University's initiative to share its data as linked data, facilitating greater transparency and reuse both internally and externally. It outlines the technologies and principles involved, while highlighting successful implementations and applications that connect educational resources and enhance user experience. Furthermore, it emphasizes the importance of collaboration among universities to create a cohesive higher education network for shared data benefits.
LUCERO - Building the Open University Web of Linked Data

- 3. Linked DataAs set of principles and technologies for a Web of DataPutting the “raw” data online in a standard, web enabled representation (RDF)Make the data Web addressable (URIs)Link with other data

So Linked Data for the OU?RAEDBPediaData from Research OutputsOpenLearnContentOROExposed as linked data, our data interlink with each other and the external world: become part of the “global data space” on the WebArchive of Course MaterialLibrary’sCatalogueOf Digital Contentgeonamesdata.gov.ukCurrently: OU public data sit in different systems – hard to discover, obtain, integrate by users.A/V MaterialPodcastsiTunesUBBCDBLP
- 6. 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 effectiveAt least 3 other UK universities have now followed our example: http://data.online.lincoln.ac.uk/, http://data.ox.ac.uk/, http://data.southampton.ac.uk/And others in other countries are setting up similar initiatives

- 18. DatasetsAlready “officially” in place:ORO: more than 18,000 publications from OU researchersPodcasts: 2,500 audio and video tracks from podcast.open.ac.uk, linked to the relate coursesStudy at the OU: more than 600 live module descriptionsOpenLearn: more than 550 Units of course materialKMi Staff and Planet newsletterCurrently being processed:OU Buildings in MK and regional centersLibrary CatalogueYouTube channelOld Courses“Reading Experience Database” project People Profiles

- 20. ApplicationsFor education Mobile podcast explorer, podcast explorer on TV OU Building Map, OU location tracker (cf. foursquare)OU Expert SearchConnecting courses/OpenLearn to relevant podcastOU Course Profile Facebook app using list of courses, “Study Buddy” app connecting facebook users to relevant coursesFor ResearchDisplay connections in a research communityResearch Data/Impact AnalysisConnection research datasets to external data
- 22. Example application: Link OpenLearn to relevant course/podcasts
- 23. Example Application: keep track of location, meetings, tutorials, at the OU
- 24. Example application: exploring research communities
- 25. Example application:Expert Search using publication information and connecting to contact information within the OU
- 26. Example application: Explore Information about a person in the “Reading Experience Database” based on data provided by DBPedia (Linked Data version of Wikipedia) New ways to look at humanities research data
- 27. The future (practically)More data… always more dataMore links, especially to external entities BBCGovernment agenciesOther universitiesMore applications:Integration into main OU websites (e.g., study at the OU)Integration into common OU applications (people profile, Facebook course profile, etc.)Support for common OU processes (REF audit, course recommendation, providing resources to AL and lecturers)Sustainability LUCERO is finishing soon and….data.open.ac.uk is becoming a core component of the OU information infrastructure…
- 28. The future (more generally) From nice demonstrators to real semantic web applicationsUse of reasoning and data mining for data consolidation and analysisNeed proper frameworks for application developers!Linked data and the Semantic Web to support researchNot only research communitiesIdentifying new research questions and collecting evidence through connected datasetsIt is not about individual Universities!Universities sharing data to benefit students and researchers: the higher education’s web of linked dataNeeds collective vocabularies, recipes, approaches, classifications… the GoodRelations of higher education?
- 29. The future (research)Linked data analytics/Linked data miningInterfaces to linked data/Making sense of linked data (with ontologies)Semantic web for activity data/personal data
Editor's Notes
- #4: Usual pitch: - data on the web = every piece of data is web addressable, so data across different places/stores/systems become linkable: the Web = 1 data space
