Sio and lre l.jpg
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 l.jpg
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 l.jpg
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 l.jpg
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 l.jpg
Problems

  • Curriculum mapping

    • Maintaince of mappings

    • Changes of curricula (historical prespective)

      • Typical example from Slovenia

        • In 1995: 8 year primary school

        • Now: 9 years
