5. What went wrong
• In 2001 believing that commercal publishers
were ready to engage in a federation of
repositories
lre.eun.org
• In 2008 School teachers rejected the
federated search
– Unstable result sets
– Unstable order
– Speed
– Is this a general rejection ?
• Many errors when end users apply Creative
Commons
6. Unexpected positive
• Adoption of the LRE application profile of the
LOM including the LRE thesaurus
lre.eun.org

28. Introducing an international educational
resource repository
• National reflexes vs. European attitude
• Impatience
• Travel well - Learning object quality
lre.eun.org
• National curriculum
• Discipline/theme oriented social tag clouds
• Searching process
• Interest of teachers evolves
• Object vs. idea/tool
• Lesson plans
• Virtual vs. face-to-face contact
- Virtual international collaboration is still an issue
