sio and lre
SIO and LRE
  • SIO: Slovenian educational network
  • Established in 1995
  • ‘Index’to educational resources
  • Based on ‘home made’ catalogue system called Trubar
  • Connection to LRE
    • Technicaly easy to connect, essentially no problems
    • All problems were (and some still are) related to compatibility of metadata of both systems
what are educational resources
What are educational resources
  • SIO
    • Metadata catalogue
    • Possible to store resources, but this is not its primary task
    • Includes also descriptions of books, didactical toys, web pages ...
    • Granularity: from assets to complete learning courses
  • LRE
    • Local storage of a resources encouraged
    • Mostly assets and short learning units
metadata mappings
Metadata mappings
  • Similar data, but differently structured
  • Classification schemes differ
    • To whom the resource is appropriate for
      • LRE: age range
      • SIO: school year
    • Classification keywords
      • LRE: fixed thesaurus
      • SIO: subject field
    • Technical differences
      • LRE: separated fileds for each author
      • SIO: list of authors (free text)
    • Metadata about availability
      • LRE: Creative Commons license is strongly recomended
      • SIO: free, public, shareware, commercial (CC is relatively new)
problems
Problems
  • Language
    • LRE is a multilingual system
    • Majority of resources is in national language
    • Problems with translations
    • English as an intermediate language at least for certain important metadata where automatic translation is not possible (title, free keywords...)
problems6
Problems
  • Curriculum mapping
    • Maintaince of mappings
    • Changes of curricula (historical prespective)
      • Typical example from Slovenia
        • In 1995: 8 year primary school
        • Now: 9 years
