PHOTODENTRO LOR, THE GREEK NATIONAL LEARNING OBJECT REPOSITORY

This paper presents Photodentro LOR, the Greek National Learning Object Repository (LOR) for primary and secondary education. Photodentro LOR hosts open learning objects: small, semantically and functionally autonomous, reusable, open educational resources, tagged with educational metadata. It is targeted to teachers and pupils and it constitutes a core part of the Greek Ministry of Education digital infrastructure for educational content for schools. The paper also discusses issues to be taken into account when designing a National Learning Object Repository for schools, and provides an overview of the Photodentro LOR design and implementation, including semantic interoperability and metadata issues, technical decisions, and workflows for content population. The big picture of the infrastructure that includes the Photodentro National Educational Content Aggregator is also given.
