13. CDA Templates What is a Template? How can it be expressed? What can I do with it?

14. What is a Template? A template is an expression of a set of constraints on the RIM that is used to apply additional constraints to a portion of an instance of data which is expressed in terms of some other Static Model. HL7 Specification and Use of Reusable Constraint Templates

15. Expression of Templates Formal Written Definition –In human readable form Explicit or Implicit HL7 Static Model –Application results in a Static Model Implementation Specific Representations –Static Model –W3C Schema –ISO Schematron

16. Features of a Template Has an Identity Can Require, Prohibit, or Suggest (constrain) –RIM Attributes –Relationships –Other Templates –Specify Cardinality –Conditional and Co-relationships Can Inherit from other Templates

17. IHE Patient Care Coordination Templates Are Content Profiles or Modules Have a formal Written Definition Result in an Implicit HL7 Static Model Use ISO Schematron for Implementation Inherit from ASTM/HL7 CCD when possible Provide Constraints on –Documents –Sections –Entries

18. Document Level Templates Template ID Summary Description Format Code for use with XDS Standards Used Data Element Table (needs Definitions) Specification –Sections –(Header) Entries Conformance Sample XML (abbreviated) Schematron
