    Agricultural Learning Repositories & Metadata Application Profiles Agricultural Learning Repositories & Metadata Application Profiles Presentation Transcript

    • Agricultural Learning Repositories & Metadata Application Profiles Nikos Manouselis , Kostas Kastrantas Informatics Laboratory Div. of Informatics, Mathematics & Statistics Dept. of Science, Agricultural University of Athens GREECE
    • Digital Learning Repositories
      • Digital Repository: system for the storage, location and retrieval of digital resources
      • Digital Learning Repository (DLR):
        • nature of resources or their description reflects an interest of use in an educational context
        • Holden C., “From Local Challenges to a Global Community: Learning Repositories Summit”, Academic ADL Co-Lab, 2003
    • A set of questions
      • Are there DLRs with agricultural content?
      • Which metadata schemas do they use?
      • Are there agriculture-specific application profiles?
      • Relation to AOS?
    • DLRs for agriculture
      • Those particularly focusing on agricultural content/stakeholders
    • DLRs for agriculture
      • Those particularly focusing on agricultural content/stakeholders
      • Generic ones that also contain some agricultural content
    • DLRs for agriculture
      • Generic ones that also contain some agricultural content
    • DLRs for agriculture
      • Those particularly focusing on agricultural content/stakeholders
      • Generic ones that also contain some agricultural content
    • Preliminary study
      • Took place during 2005
      • Examined 59 well-known generic DLRs
        • identified 27 DRLs with agricultural content
      • In a total of ~881,000 educational resources:
        • … only 3,201 resources (0.36%) related to agricultural topics
        • Tzikopoulos et al., "Investigating Digital Learning Repositories' Coverage of Agriculture-related Topics", ITAFE 2005.
    • 34.5% of resources not classified (generally: agriculture)
    • Majority uses a metadata standard (mainly IEEE LOM or LOM based , and Dublin Core )
    • LR metadata
      • Learning Technology specifications & standards have been continuously developed since early 1990s
      • IEEE Learning Object Metadata (LOM) standard widely adopted & implemented
      • Competing schemas:
        • DC-ed (but, effort to come closer to LOM)
        • ISO/IEC JTC1 SC36 LRM (under development)
    • About IEEE LOM
      • Nine categories of elements
        • 76 elements, all optional
      • Produced by IEEE Learning Technology Standards Committee
        • adopted as an IEEE standard on 2002
      • Past 3 years: studied in depth by ISO/IEC JTC1 SC36 WG4
        • Interesting critique: Friesen N. (2004) “International Survey of Learning Object Metadata Implementation” (for ISO/IEC)
    • LR metadata in agriculture
      • IEEE LOM application profiles
        • CG LOM Core (CGIAR)
        • BEN: Biosci Education Network (AAAS)
        • BioTune (Netherlands)
        • … and some of our work:
          • BIO@GRO LOM AP (organic agriculture)
          • Organic.Edunet LOM AP (agroecology)
          • ReGov LOM AP (rural SMEs’ development)
      • Other approaches
        • FAO’s Agricultural Learning Resource AP (Ag-LR AP)
        • ICRICAT, IIT Kanpur, IIT Bombay et al.?
    • Synergies with AOS
      • Use AGROVOC for classification purposes inside LRM schemas
        • Use AGROVOC as a web service
          • … CGIAR’s DLR already does this
        • Use an AGROVOC subset/specialization
          • E.g. AGROVOC-based Agroecology ontology
          • Implement separately? Include into AGROVOC?
          • Do special domains require other terms and/or relations?
      • Sanchez-Alonso S. & Sicilia M.-A., “Using an AGROVOC-based ontology for the description of learning resources on organic agriculture”, MTSR 2007.
    • Potentially interesting…
      • Harmonization of agricultural LRM
        • Towards a commonly accepted schema?
        • Commonly accepted mappings between widely used implementations? (FAO’s Ag-LR AP, CG LOM Core, …)
      • Connection of agricultural DLRs with federations of generic DLRs
      • Organic.Edunet federation:
        • Link to ARIADNE Foundation & GLOBE Consortium
        • Query propagation using the Simple Query Interface (SQI)
      • IMS Global Learning Consortium specification ( http://www.imsglobal.org/lode.html )
