The document discusses mEducator, a best practice network funded by the European Commission to compare solutions for sharing medical educational content across learning management systems. It presents two approaches: mEducator 2.0, which uses loosely coupled LMSs via mashup technologies, and mEducator 3.0, which links LMSs via linked services and publishes educational resource metadata as linked data. The goal is to enable discovery, retrieval, rating, and repurposing of educational content irrespective of the LMS used.
