Pieter,

With respect to the 'rules' bit of ADL, and also GDL, there is a new draft 'Expressions' spec in the BASE component <http://www.openehr.org/releases/BASE/latest/docs/index>. This is a working draft, and partly lifted from ADL/AOMs specs (those now just include this one), plus some extensions to show how rule extensions are done properly.

This spec proposes an improved syntax, but it's definitely not finished (e.g. I am thinking of getting rid of the $var style syntax), and it would be great to have some other collaborators on it who have a lot of experience with expressions / rules systems. So please have a look and feel free to comment - comments here probably make sense since others may be interested.

The draft of this spec will be released soon in a new release of the BASE component. All that means is that changes from then need to be documented by PRs and CRs in the normal fashion.

It certainly does validate specs. In fact, it already has caused some 
corrections to both the specs and the ANTLR-grammar.

And we already found a few more issues in the specs. I’ll soon file an issue 
report about the rules section, to specify how to handle operators on 
multiple-valued path expressions without a for_all :)
