Digital learning repositories
Digital Learning Repositories Profiles

  • 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
A set of questions Profiles

  • Are there DLRs with agricultural content?

  • Which metadata schemas do they use?

  • Are there agriculture-specific application profiles?

  • Relation to AOS?


Dlrs for agriculture
DLRs for agriculture Profiles

  • Those particularly focusing on agricultural content/stakeholders


Dlrs for agriculture1
DLRs for agriculture Profiles

  • Those particularly focusing on agricultural content/stakeholders

  • Generic ones that also contain some agricultural content


Dlrs for agriculture2
DLRs for agriculture Profiles

  • Generic ones that also contain some agricultural content


Dlrs for agriculture3
DLRs for agriculture Profiles

  • Those particularly focusing on agricultural content/stakeholders

  • Generic ones that also contain some agricultural content


Preliminary study
Preliminary study Profiles

  • Took place during 2005

  • Examined 59 well-known generic DLRs

    • identified 27DRLs 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.



Majority uses a metadata standard (mainly ProfilesIEEE LOM or LOM based, and Dublin Core)


Lr metadata
LR metadata Profiles

  • 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
About IEEE LOM Profiles

  • 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
LR metadata in agriculture Profiles

  • IEEE LOM application profiles

    • CG LOM Core (CGIAR)

    • BEN: Biosci Education Network (AAAS)

    • BioTune (Netherlands)

    • …and some of our work:

      • [email protected] 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
Synergies with AOS Profiles

  • 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
Potentially interesting… Profiles

  • 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)
