I have uploaded a new ADL 1.5 and AOM 1.5 specification, showing recent major improvements:

- new identification approach
- removal of AOM CONSTRAINT\_REF class
- removal of AOM C\_REFERENCE\_OBJECT class
- simplification of archetype terminology

They will contain a errors in prose parts, but the formal parts should be reasonably good. I still have to do a proper review. See:

- [ADL 1.5 spec](http://www.openehr.org/releases/trunk/architecture/am/adl1.5.pdf)

- [AOM 1.5 spec](http://www.openehr.org/releases/trunk/architecture/am/aom1.5.pdf)  
The various grammars are visible here.

- ADL outer syntax - [here](https://github.com/openEHR/adl-tools/tree/newdiff/components/adl_compiler/src/syntax/adl/parser)
