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

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 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 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...)

Problems Curriculum mapping

Maintaince of mappings Changes of curricula (historical

prespective) Typical example from Slovenia

In 1995: 8 year primary school Now: 9 years
