I think this thread has gone a little off the rails. There are predefined (by FHIR) URIs for value sets that are defined just as descendants of a single concept, or members of a reference set.
For an enumeration of concepts and/or a snomed ECL expression, then you can use a Fhir ValueSet and give it a URI. ValueSets also generalise beyond just SNOMED (LOINC for example). Furthermore, there are existing tools to expand them to the set of member concepts, you can include metadata, manage versions etc. This is much more than you get just by encoding ECL in a URI. In case anyone wants to play with ECL expressions and their evaluation you can go here for an interactive page: https://ontoserver.csiro.au/shrimp/ecl.html Also, some brief documentation and click-through examples here https://ontoserver.csiro.au/shrimp/ecl_help.html Regards Michael Sent from my iPhone On 3 May 2017, at 9:08 pm, Diego Bosc? <yamp...@gmail.com<mailto:yamp...@gmail.com>> wrote: Seems like the only way right now is creating refsets and referencing them with standard URIs... 2017-05-03 13:02 GMT+02:00 Bert Verhees <bert.verh...@rosa.nl<mailto:bert.verh...@rosa.nl>>: On 03-05-17 12:53, Thomas Beale wrote: On 03/05/2017 11:40, Bert Verhees wrote: On 03-05-17 12:36, Thomas Beale wrote: 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. Stupid.
