The only missing part, now that I look at the SNOMED Compositional Grammar <https://confluence.ihtsdotools.org/display/DOCSCG> and Expression Constraint Language <https://confluence.ihtsdotools.org/display/DOCECL> specs, is how to create a URI (which is the type of a term binding in ADL2 <http://www.openehr.org/releases/AM/latest/docs/AOM2/AOM2.html#_terminology_package>) from a post-coordinated expression or constraint expression. This should be trivial, but I don't see where SNOMED has specified it.

True, I was looking for that also, a few days ago. I don't have time to read much now, but there is a document on the SNOMED site on URI's, maybe it is in there? I can take a look later or look in my documentation, I have course materials. I come back to this tomorrow if not someone else already has.

The URI spec is here <https://confluence.ihtsdotools.org/display/SLPG/SNOMED+CT+URI+Standard>, but it doesn't address URIs for expressions either.

(All the SNOMED language specs appear to be here <https://confluence.ihtsdotools.org/display/SLPG/SNOMED+CT+Computable+Languages> these days - nice and convenient, and also nicely published. We probably should go back to linking to them somewhere on the openEHR site).

I checked my course materials from last year, lucky I found it quickly, there is not any mentioning of URI's for expressions, so I guess it does not yet exist.
