1. Some experiences from the CALIBRATE project V. Batagelj, I. Kavkler, M. Lokar, Faculty of mathematics and physics, University of Ljubljana

2. 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

3. 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

4. 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)

5. 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...)

6. Problems Curriculum mapping Maintaince of mappings Changes of curricula (historical prespective) Typical example from Slovenia In 1995: 8 year primary school Now: 9 years
