What is mEducator?
A Best Practice Network (BPN) co-funded by the – eContentplus 2008 programme of the European
Commission, Information Society and Media Directorate-General, Digital Content & Cognitive Systems
Start Date: May 1st , 2009 Duration: 3 years Contract Reference: ECP-2008-EDU-418006
As a BPN, it compares different solutions (2) to draw best practice recommendations

How do people share nowadays
Usually expose individual repositories (instead of allowing distributed searches)
Case of search engines (e.g. Google):– data are restricted to specific kinds of documents
(such as HTML, PDF… i.e. do not harvest metadata as such)
Minimal sharing mechanisms… Minimal interoperability between systems… Peer collaboration ?

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
co-funded by the European Commission eContentplus programme
6
Ultimate goal…
provide mechanisms for content publishing, discovery, & retrieval
analyze policies and mechanisms for content evaluation, rating, renewal and repurposing
elaborate on intellectual property rights for educational material
test the impact of true interoperability, repurposing, enrichment, and embedding of a variety of highly attractive and up-to-date learning resources in each of the partners’ curricula
provide recommendations on how to implement interoperable educational content discovery and retrieval networks

mEducator “content”
refers to any type of educational material with a registered history of creation and evolution
Is linked with – specific educational goals and objectives– learning outcomes – educational contexts/settings
comes recommended with – certain types of teaching methods & strategies– and/or assessment

What is Repurposing?
‘...transforming a learning resource initially created for a specific educational purpose in a specific educational context in order to fit a different new purpose in the same or different educational context’As defined in deliverable mEducator D3.1 Content Repurposing: Definition of Repurposing Reasons & Procedures
•Repurposing to different languages •Repurposing to different cultures •Repurposing for different pedagogical approaches •Repurposing for different educational levels •Repurposing for different disciplines or professions •Repurposing to different content types•Repurposing for different technology•Repurposing for people with different abilities•Repurposing to educational content•Changes in the content itself

Describing Repurposing histories:Metadata schema extensions

Metadata Scheme Overview
Analyse existing standards Relevant fields from
existing standards
Identify additional pedagogical information
Explore requirements for repurposed content
Fields to describe repurposing history
Fields describing additional pedagogical
information
Identify any additional critical information
Additional fields
mEducator Metadata Scheme

The competing perspectives (tensions)
End users directly involved in metadata creation….but current metadata standards are difficult to use
– Semantic ambiguity / overlapping– Time consuming process– Not all fields are meaningful (from a sharing perspective)– …where is the learning?
Controlled vocabulary/terminology vs. user vocabulary (taxonomies vs folksonomies)

Proposal of a Tree-based Conceptual Model (Based on LOM/HealthcareLOM)
Representation of the Tree Model in XML
– XML Schema, XML Example File Moved towards a Graph-based Conceptual Model (RDF Model) Proposal of controlled vocabularies for some metadata
elements and linking of them with the RDF Model Representation of the RDF Model in XML (RDF/XML)
– RDF Schema, RDF Example File

mEducator will test 2 different approaches for sharing
1. loosely coupled LCMSs– via mashup
technologies2. federated architecture
– semantic web services / open linkedservices

federated architecture
co-funded by the European Commission eContentplus programme
Solution 2 overview
Current 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…)
