SNOMED CT Expression Constraint Language

@Former user (Deleted)

Discuss recent feedback about the ECL

OUTCOMES

1. The group agreed to add new operators to the ECL specification to support the FHIR community's use case for immediate children/parents. The preferred syntax was "<!" and ">!" .

2. The group decided that comments should be added to the the brief syntax of the ECL using the "/*... */" syntax.

SNOMED CT Template Syntax

@Former user (Deleted)

Review discussion on optionality and populating attribute groups:

1. Scope and purpose of syntax

   1. Extract/disentangle SNOMED CT (and SNOMED CT-relevant) content from a FHIR Condition resource (i) into a free-standing and ‘recognisable’ SNOMED CT expression, whilst (ii) ‘leaving nothing behind’ which may be of relevance to further processing

   2. Specify mappings from FHIR value sets (e.g. Condition.clinicalStatus) into SNOMED CT

   3. Transform the extracted expression into an ‘optimally-processable’ SNOMED CT expression (in particular grouping body site values with morphology)

   4. Specify constraints on what the extracted/disentangled SNOMED CT expression could or couldn’t contain (by e.g. cardinality instructions).

NOTE - The rest of this discussion will be carried over until the next meeting.
