  1. 1What is HL7?Not software, not a language: a messaging standard. The analogy that makes it click.
  2. 2Anatomy of a messageSegments, fields, components, delimiters. We dissect a real message top to bottom.
  3. 3Message typesADT, ORU, ORM. How the MSH-9 field decides everything else.
  4. 4Segments, one by oneMSH, PID, PV1, OBR, OBX. What each one says and where to find it.
  5. 5Transport and interface enginesMLLP, acknowledgements, Mirth. How a message actually travels.
  6. 6The move to FHIRWhy FHIR does not bury HL7 v2, and how the two coexist.
