## Post #1 by @Wajahat_Ali

I am working on running an end to end scenario between HL7 CDA and openEHR. For the very said reason I have performed ontology mappings of the two standards ontologies for the mapping file to be generated. Other than the mapping file, I found few concepts of HL7 CDA schema to be mapped with openEHR concepts. The list of the mappings are (Left hand side are HL7 CDA concepts while right hand side concepts are of open EHR)

1. Author *equals* Related Party
2. CDA Code *equals* Archetype Details
3. CDA ID *equals* UID
4. CDA Title *equals* Name
5. Custodian *equals* Participation
6. Data Enterer *equals* Party Reference
7. Patient Role *equals* Role

I need validity of the mappings, if anyone can evaluate the mappings and if wrong kindly guide me by providing me correct counterpart entities. I would also like guidance from an expert for validity of future mappings as well. I will be grateful for support in this regard.

Best Regards,
Wajahat Ali

Hi Wajahat,

I think this is a more accurate mapping:

1\. Author equals COMPOSITION/composer

2\. CDA Code equals "Document Type" \- no direct RM attribute
It could be
  a\) Hard\-wired into transforms from openEHR documents
   b\) Represented as a an archetyped node in a COMPOSITION Report archetype
   c\) Carried as a term Mapping on the Document Name i\.e
Composition/name/mappings/code\_mapping \.\.

3\. CDA ID equals COMPOSITION/UID \.

4\. CDA Title equals COMPOSITION/name \(as DV\_CODED\_TEXT\)

5\. Custodian equals
   Participation or
   COMPOSITION/context/health\_care\_facility or COMPOSITION/composer

6\. Data Enterer equals CONTRIBUTION/version/audit/commiter

7\. Patient Role equals Role

Ian

Hi,

For 2., if a template represents a document, then archetypeDetails.templateId can be considered as the "document code".

Cheers,
Pablo.
