digital learning repositories
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
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
DLRs for agriculture
  • Those particularly focusing on agricultural content/stakeholders
dlrs for agriculture1
DLRs for agriculture
  • Those particularly focusing on agricultural content/stakeholders
  • Generic ones that also contain some agricultural content
dlrs for agriculture2
DLRs for agriculture
  • Generic ones that also contain some agricultural content
dlrs for agriculture3
DLRs for agriculture
  • Those particularly focusing on agricultural content/stakeholders
  • Generic ones that also contain some agricultural content
preliminary study
Preliminary study
  • 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.

lr metadata
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
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
LR metadata in agriculture
  • 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
  • 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…
  • 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)
