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

Know-Why ?

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
