What is eViP

• eViP = electronic Virtual Patients• 3 year project co-funded by the European Union• Aim: create a bank of repurposed and enriched multicultural

virtual patients• Development of the eViP application profile for exchanging

virtual patient cases between systems



eViPSeptember 2006

eViP application profile (2.0.1)


• MedBiquitous Virtual Patient spec 0.48• Standard for Learning Object Metadata (LOM)• MedBiquitous Healthcare Learning Object Metadata Spec

(Healthcare LOM)• SCORM packages • Conformance testing suite

External to the profile:• IMS Question and Test Interoperability specification (QTI)• W3C Timed Text (TT) Authoring Format 1.0

Usage statistics


• Semi-linear systems use many specialized fields• Linear systems use mostly text elements (VPDText)• Branched systems use many Link and Rule elements• All elements in DataAvailabilityModel (DAM) are used• 3 systems use XtensibleInfo• Not used elements: Conditional Rules, Counter, Timer,

Specialized Body Locations

Challenges - Example


• Importing and exporting from branched to linear and vice versa:

Best practice guidelines


• Possibility to override exported content• Conformance level testing

• Package validation• XML/XSD validation• Import validation• Runtime validation

• External specifications handling• XtensibleInfo (add schema files and create

namespace)• e.g. IMS QTI, W3C Timed Text format

• Use same version of specification

automated by testing suites

manually in target system

September 2006

Future Work


• Using the import/export functionality in "real life"• Evaluate the semi-automatic repurposing process• Develop best-practice guidelines for this process• Increase number of case studies• Consider updates of MVP• Dissemination of results • Storage of consent forms• eViP profile metadata• Storing VP's repurposing lifecycle
