Next priorities

@Former user (Deleted)

Recent publication of:

• SNOMED CT Template Syntax v1.0 (http://snomed.org/sts)

• SNOMED CT Expression Template Language v1.0 (http://snomed.org/etl)

Outstanding work items:

• Updates to SNOMED CT URI standard

  • Current URI standard - http://snomed.org/uri

  • Proposed additions - SNOMED CT URI Standard

• Development of SNOMED CT Query Language

  • Proposed scope and examples: SNOMED CT Query Language

• SNOMED CT Expression Constraint Template Language

• Addition of new features to the SNOMED CT Template Syntax

• Repository of normative expression constraint results / Failing cases

  • Implementers to generate EOL delimited format

  • File naming of examples and the corresponding results

  • Sorted alphabetically

  • Substrate - 20170731 international edition

  • Compare implementation outputs

• Others?

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?
