Concepts

This part explains the ideas you need to use FerroEHR effectively. If openEHR is new to you, read the openEHR primer first — it covers the Reference Model, archetypes and templates, versioning, and AQL without assuming prior knowledge. Then System architecture shows how FerroEHR is put together and where your data actually lives, so the behaviour you see through the API makes sense.

You do not need to read these before Getting started — but a few minutes here will make every later chapter clearer.
