Problem
◦ Lack of standardisation mechanisms, that
enable state-of-the-art of medical educational resources to be discovered,
retrieved, shared and re-used across European Academic Institutions
MedBiquitous Annual Conference 2011
Solution
◦ Standardised format of description of the resources by means of metadata
◦ Metadata need to be described by state-of-the-art e-learning standards
and make use of their many advantages Semantic Web, Linked Data
Aim◦ To improve medical & healthcare education
2
General Characteristics To describe core data about the resources
To describe educational aspects of the resources
To be implemented by state-of-the-art specifications
MedBiquitous Annual Conference 2011 3
Need to be widely used (interoperable) Reusing existing e-learning standards
Should not reinvent the wheel Extending e-learning standards to describe new
concepts i.e. Repurposing, Companionship, Attention
Healthcare LOM describes medical resources
Lack of interlinking

Standardisation format in order to enable
sharing and retrieving of resources is essential
Choice of the right format (RDF/XML) will link
the data of the Web. Benefits:
◦ Access existing knowledge
◦ Interoperability between resources
Shift towards an Ontology

educationalObjectives
Aim: To enable specialized state-of-the-art medical educational content of varying types to be discovered, retrieved, shared and re-used across European higher academic institutions.
How: By implementing and evaluating two different solutions
• A “mashup” platform that aggregates content published in isolated Learning Content Management Systems (LCMS)• A federated architecture of LCMSs based on Semantic Web Services for search, interchange and delivery of learning objects
