Notes from the interface layer

We build open-source parsers for the healthcare standards (HL7 v2, X12, C-CDA, and the rest), and we do the integration work that uses them. This is where we write about that work.

Expect practical things: how a particular interface actually behaves, what breaks in a migration, where a spec is ambiguous and how we read it. Not launch posts or hot takes, but the notes we would want to find ourselves when an interface is misbehaving at 2am.

A standing rule here, same as in the code: we will not invent a vendor quirk we have not seen, and we will not pretend an edge case is solved when it is not. If something is uncertain, we say so.

More soon.
