Implementation Guides
Clinical domain knowledge
Ready-to-implement
Validation rule set
Templates
“Re-usable bits”
Abstract formalism
Formalism relates IG to Reference Information Model
Validation rule set derived from model
Benefit of templates
Automate rule set creation
Relate implementations back to single model in such a way that can understand relationship between “reusable bits” at any level

3. Validating CDA document types
.xPath, .xsl,
Schematron
prose √
.xsd
CRS
.xml
Validates against generic schema
<Section
code=Plan> √
XPath validation of Implementation Guide requirements

4. Templates and IGs: ?
Care Structures ?
