1. September 2006 www.virtualpatients.eu T. Calinici, D. Davies, J. Donkers, I. Hege, J. Heid, A. Kononowicz, L. Woodham, N. Zary (Technical reference group of eViP) Implementation of the MVP standard by four European VP systems – challenges and recommendations

2. eViP September 2006 Overview What is eViP? Participating systems Implementation of the MVP standard Challenges and Best Practice Guidelines Future Work www.virtualpatients.eu

3. eViP September 2006 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 www.virtualpatients.eu

4. eViP September 2006 eViP application profile (2.0.1) www.virtualpatients.eu 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

5. September 2006 Participating systems www.virtualpatients.eu CASUS Campus Web-SP Open Labyrinth

6. September 2006 Participating systems www.virtualpatients.eu CASUS Campus Web-SP Open Labyrinth University of Heidelberg, Germany Model: semi-linear Terminology-based system Implementation: using XSLT VP Import Export CAMPUS VP XML CAMPUS eViP zip XSLT

7. September 2006 Participating systems www.virtualpatients.eu CASUS Campus Web-SP Open Labyrinth Karolinksa Institutet, Sweden Model: semi-linear Implementation: Java model of MVP Java model of MVP WEB-SP VP XML files zip file ???

8. September 2006 Participating systems www.virtualpatients.eu CASUS Campus Web-SP Open Labyrinth St. Georges University, UK Model: branched Implementation: Using a C#.Net model C#.Net model of MVP C#.Net model of MVP OpenLabyrinth VP XML files ??? zip file

9. September 2006 Participating systems www.virtualpatients.eu CASUS Campus Web-SP Open Labyrinth University of Muenchen, Germany Model: linear Implementation: using Java model, Castor Java model of MVP Java model of MVP CASUS VP XML files Castor zip file

10. eViP September 2006 Usage statistics www.virtualpatients.eu 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

11. September 2006 Challenges - Example www.virtualpatients.eu Importing and exporting from branched to linear and vice versa: Node Branched VPLinear VP

12. September 2006 Challenges - Example www.virtualpatients.eu Branched structure in OpenLabyrinth Linear structure in CASUS

13. September 2006 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 (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

14. September 2006 Future Work www.virtualpatients.eu 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
