1.0.0 - Initial Release, August 2005

The majority of content in the initial release was built via an automatic migration from the old C-CDA Examples repository into this IG.

All files (with few exceptions) were copied directly into the IG with minimal content changes:

• Grouping was set to the original folder name
• Example filename was set to a kebab-case form of the original example name (i.e. “Not Allergic to Peanuts” became “allergies-not-allergic-to-peanuts”)
• All namespace declarations (xmlns="urn:hl7-org:v3", and xmlns:xsi=... and xmlns:sdtc=...) were moved to the root element
• Superfluous <structuredBody> and <component> were removed from examples that start from <section>
• Cleaned up some bad XML characters like “pretty” quotes and nonprintable control characters
• Consistent formatting applied to all examples (e.g. 2-space indentation, maximum line lengths)
• Descriptions were set from the Readme.md files
• Associated profiles were set by parsing the templateIds from the Readme.md files
• Approval status and dates were set by parsing strings in the Readme.md files

The following examples were NOT brought over via automatic process:

• Any example with Approval Status: Withdrawn in the Readme.md file
• Any example missing an .xml file (e.g. Medication Timing notes). These were all brought over manually, cleaned up for Markdown / HTML formatting, and listed under the Guidance menu.
• Guide Examples - These are already in the C-CDA implementation guide, though will likely be migrated here in a future version
• Full-Document Examples
• Stylesheets
• A few examples that led to identified issues with the SD publication of C-CDA or CDA as listed below:
  • Period elements with overridden xsi:type="IVL_PQ" - currently crashes the publisher
    • Med every 4-6 hours
    • Med oral liquid PRN

A few samples were modified manually after initial migration

• TemplateIds from the Companion Guide, C-CDA 3.0, and beyond were added
• Nullified addr and telecom fields were added to author elements where required
• Procedure act and observation examples were all migrated to use <procedure>
• Various CDA schema errors and C-CDA schematron errors were corrected
• Immunization Not Given updated with code -> value for C-CDA 3.0
