Concrete Domains

SNOMED International Proposal for Representing Concrete Domains in RF2

Uses Cases - Drug strength values, Singapore Drug model also uses Booleans for eg "is Manufactured / is Vaccine" (xsd standard states true ,false)

Potential Impact to vendors / NRCs:

Roadmap: Consultation Summer 2019 targeting first release July 2020 and concepts-as-numbers inactivation July 2021

Time permitting: Migrating content to a dependent module

@Peter Williams

Refset Metadata

@Peter Williams

10

This topic comes from SNOMED on FHIR

Also TRAG item: Reference set metadata See Agenda item 17 and consider in wider context of machine readable metadata item 11

In fact, this metadata may be more widely useful when applied to a module.

Suggestion that we could use the FHIR standard which already defines metadata. DM suggests a JSON format which would be extensible unlike a column based solution.

@Kai Kewley

Classification Service with documentation available in GitHub

• Makes use of the Snomed Owl Toolkit which is capable of converting SNOMED CT Snapshot files into an OWL ontology file (functional syntax) for use in 3rd party tools such as Protégé.

• Review Necessary Normal Form for Inferred relationships (draft)

Requirements and recommendation for representing SNOMED CT in a standalone OWL file

@Former user (Deleted)

@Yongsheng Gao

Use Cases: Reputational risk, desirable to be able to assert correct canonical / sanctioned representation. Classifier research - allows for reproducible results.

Specification for representing SNOMED CT in OWL

Revisit "Negative Delta"

@Peter Williams

10

At request of EAG - need to revoke/delete a published component. Comments added to Negative Delta.

See TRAG agenda item #

Notify @Andrew Atkinson

Use cases:

Two groups: where audit is desired (eg technical issue) and where it is not (IP, un-processable characters)

1. Removing IP - suggestion to blank out particular field ("~") while leaving row.

2. Conflicting Rows ie no clear state (technical issue, not content) - suggestion to subsequent delta clarifying row.

3. Clinically dangerous historical error in before-previous release.
