Querying repositories of OER descriptions: The challenge of educational metadataschemas diversity

Abstract

Personalized applications like recommendation systems or open adaptive hypermedia require to facilitate reuse and interoperability of educational resources. Thus we have to solve the problem of discovering educational datasets and the problem of the fragmented landscape of competing metadata schemas. In this paper, we compare a subset of metadata schemas used by educational datasets obeying the Linked Open Data principles and we propose mappings between them
