The recommended method of transforming data from CCD to HL7 is to use InterSystems SDA as an intermediary format. Use pre-built XSLTs to convert from CDA to SDA , and then create a DTL transformation to map the SDA to HL7. Here are the names of some related books:

  • CDA Interoperability with SDA
  • The InterSystems Clinical Data Model: SDA (in future releases, this will be renamed to "SDA: InterSystems Clinical Data Format")
  • Developing DTL Transformations
