What went wrong• In 2001 believing that commercal publishers

were ready to engage in a federation of repositories

• 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 CreativeCommons

• Adoption of the LRE application profile of the LOM including the LRE thesaurus

Introducing an international educational resource repository

• National reflexes vs. European attitude• Impatience• Travel well - Learning object quality• 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• License issue; CC extremely useful
