What is eViP about?
• eViP = Project about electronic Virtual Patients• 3 year (2007-2010) project, 9 partners and co-funded by the
European Union
• Main outcomeCreate a bank of repurposed and enriched multilingual and multicultural virtual patients and share them

The goals of the sub-project
• Development of the systematic method for exchanging virtual patient cases between VP systems
= eViP application profile
• Implementation of the eViP application profile by 4 VP systems
= import/export of VPs

Result: eViP application profile
www.virtualpatients.eu
The aim of application profiles is the selection and re-use of existing elements to tailor to the needs of a given group of users.
• MedBiquitous Virtual Patient 0.48• MedBiquitous Healthcare Learning Object Metadata (Healthcare LOM)• SCORM packages • Conformance testing suite

Challenge 1 - Implications
www.virtualpatients.eu
• Import all branches• Put information about (best) next node(s), end nodes(s) and
start node into imported VP
• Has to be done manually

How the VP systems use different parts of the specifications
www.virtualpatients.eu
Differences• Semi-linear systems use many specialized fields• Linear systems use mostly text elements (VPDText)• Branched systems use many Link and Rule elements
Similarities• All elements in DataAvailabilityModel (DAM) are used• 3 of the 4 systems use XtensibleInfo• Not used elements: Conditional Rules, Counter, Timer,
Specialized Body Locations

Best practice guidelines
www.virtualpatients.eu
• Possibility to override exported content• Conformance level testing
• Package validation• XML/XSD validation• Import validation• Runtime validation
• External specifications handling• XtensibleInfo • e.g. IMS QTI, W3C Timed Text format
• Use same version of specification
automated by testing suites
manually in target system
