mEducator central idea• discover, retrieve, use, rate, re-use and re-purpose educational content irrespective of any Learning Management System use

• providers and users of such content may be – expert instructors (academics / health professionals)

– students / learners

• YouTube metadata is not enough to describe the purpose of the content.– Only one description is possible

Solution 2 architecture:

(1) federated access to eLearning repositories across the Web:•integrating existing educational resources from across the Web using Linked Data/Linked Services technologies •enabling federated queries for educational resources by end users and 3rd party applications

(2) publishing educational resource metadata as Linked Data: •following state of the art Linked Data principles (URIs, RDF, SPARQL, interlinked data with established vocabularies such as SNOMED, MESH, GALEN…)
