+== Notes
+=== Mapping
+
+As noted in <<Implementation of Business Logic>> the business login is independent of the
+serialization, in the spirit of hexagonal architecture. This of course requires some mapping,
+where we mostly use https://mapstruct.org[MapStruct] for. This necessitates some limitations in
+data model naming conventions. MapStruct uses a fixed und quite unflexible accessor naming strategy,
+so you can't really decide that protocol buffers should have one convention but Immutables another.
+Especially for Immutables we are forced to use JavaBeans-style naming convention, although this is
+not a JEE application.
