Step 1: Requirements analysis Existing template tools
Model-Driven Health Tools (MDHT) Trifolia Workbench DECOR Templates Registry Business Process
Requirements Model Interchange Format (MIF) Several other approaches, e.g. UK, NZ How fits FHIR into the game?

Tabular viewOne of many ways to present DECOR templates
Distraction from “fixed” items
Focus on instance construction
Validation as a “side-effect”Your actual work starts
here!!!

Chapter I: C-CDA and Trifolia Further findings
Need of an extended version management (which is required by DECOR)
Id and Name Version date Status code Template life cycle support
Templates Meta Data (see Templates Registry Business Process Requirements)
Artefact Registry (HingX)

Chapter I: C-CDA and Trifolia Further findings
DECOR would use less embedded schematron assertions
e.g. for choices, data type assertionscount(cda:assignedPerson | cda:representedOrganization)=1SHALL contain exactly one [1..1] assignedPerson exactly one [1..1]representedOrganization
C-CDA: mean # of schematron per template: 1.1 ELGA: 133 templates, 17 inline asserts (mean 0.13)
General problem: expression of co-constraints
