Questions from Daniel

@Former user (Deleted)

Discuss questions from Daniel (if time permits)

1. to support expression repositories (i.e. where the substrate is dynamic in that expressions could be added), do we need to add the ability to use the ECL to apply constraint operators to post-coordinated expressions, i.e. where a piece of the ECL string is to be interpreted as a SCG expression, e.g. << [ 404684003 | Clinical finding (finding) |: 363698007 |Finding site (attribute)| = 10200004 | Liver structure (body structure) | ]? This would correspond to a DL query.

2. to support potential expansion of the SNOMED CT logic profile, do we need to extend SCG to support axioms as opposed to only expressions, for example to allow (non-hidden) GCAs to be stated in SCG?

3. we need an SNOMED CT OWL specification, i.e. how is SNOMED CT (concepts and descriptions) represented in OWL. Is this within the scope of this group?
