  1. The Ensemble Project: Using Fedora to Support the Development of the Semantic Web for Education Agustina Martinez, Patrick Carmichael and Louise Corti University of Cambridge & University of Essex

  2. The Ensemble Project • Semantic Technologies for the Enhancement of Case Based Learning • 3 Year, £1.5 Million ESRC/EPSRC Project: Research, Development and Implementation (2008-2011) • “working with teachers and students in undergraduate and postgraduate courses to explore both the nature and role of the cases around which learning is focused, and the part that emerging semantic technologies can play in supporting this learning” • A big, happy interdisciplinary and multi-institutional extended family … • Website: http://www.ensemble.ac.uk Open Repositories, May 18-21 2009

  3. Semantic Web Technologies • Backend: archiving systems and tools for data management • Digital repositories and libraries, with data and/or metadata in differing formats • Web services: lookups, converters, searches (i.e. external data providers) • Middleware: data aggregation and semantic data management • Triplestore: large data aggregators containing data, metadata, vocabularies, ontologies and sets of rules • Endpoints and APIs to allow querying the Triplestore • Frontend: presentation and visualization of data • Web Interfaces, portals, visualization tools, personal information managers Open Repositories, May 18-21 2009

  4. Fedora Configuration 1: Basic Search FEDORA OAI-PMH Feed DC API-A “GET” RELS-EXT XLS Inline RDF One Fedora Object Open Repositories, May 18-21 2009

  5. RI Search Fedora Configuration 2: RI Search FEDORA OAI-PMH Feed DC API-A “GET” RELS-EXT XLS Mulgara Triplestore Inline RDF Open Repositories, May 18-21 2009

  6. SPARQL Endpoint Fedora Configuration 3: Custom search FEDORA OAI-PMH Feed DC API-A “GET” RELS-EXT XLS Mulgara Triplestore Inline RDF Custom Search Open Repositories, May 18-21 2009

  7. Sparql Endpoint • UG Plant Science Fieldwork • Plant Distribution in the Mediterranean • Draws on the GBIF data bank • Aggregates data so queries can run across them, and then offers visualization of the results • The data is accessed through an SPARQL ‘Endpoint’ Open Repositories, May 18-21 2009

  8. What’s next • Educational Evaluations Archive • ESDS Archive: ‘The Edwardians: Family Life and Work Experience Before 1918’ • Global Events: Earthquakes Open Repositories, May 18-21 2009

  9. Summary • Fedora Digital Repository provides a framework to store large and heterogeneous data • Not only access to the metadata descriptions but access to the actual data • Data structured and defined in semantic-ready format • Triplestores like Mulgara enable to aggregate and reason across different data sources • Visualization and presentation tools • Process semantic-ready data and present the information in different formats Open Repositories, May 18-21 2009

  10. Questions Open Repositories, May 18-21 2009
