I'm with Ian on this. The only use of post coordination is hard and requires complex tooling support that is way beyond any value you get. I would say even laterality & other qualifiers should go in the information model and not in the terminology if you have the choice.
If you are instead talking about ECLs expression constraint language, then you might want to look at http://ontoserver.csiro.au/shrimp/ecl which provides a UI for constructing ECL expressions and evaluates them as well. It also has links to summary documentation and sample expressions.

You use them to create new concepts not available in the SNOMED release. They are built using the SNOMED CT Compositional Grammar. In the archetypes they could be used for the semantic binding of the structure (atNNNN codes), or for data values in coded data typeshttps://confluence.ihtsdotools.org/display/SLPG/SNOMED+CT+Compositional+Grammar https://confluence.ihtsdotools.org/display/SLPG/SNOMED+CT+Compositional+Grammar - SNOMED CT Expression Constraint Language is an extension of the compositional grammar that allows building SNOMED CT subsets intensionally, i.e., by restriction or querying. This allows you to create a subset by defining an expresion. This can be used to constraint coded values (acNNNN codes) https://confluence.ihtsdotools.org/display/DOCECL/Expression+Constraint+Language+-+Specification+and+Guide Now, if your question is about how to combine the modeling of archetypes and the modeling of SNOMED CT expressions, this paper could give you some hints. It's old, but still relevant. There are clear areas for modeling information as archetypes or with terminologies, but there is also a grey area where both solutions are applicable.

One of the things they were interested in discussing was how to use postcoordinated SNOMED CT (expression constraint language) expressions with openEHR, which I know nothing about. Does anyone have any knowledge about or experience with this?
