While deprecated, codes for antecedent SNOMED versions (SNOP, SNOMED, SNOMED II, SNOMED International (3.x), and SNOMED RT) exist in records. For this legacy data to be accurately and unambiguously communicated, URIs need to be defined for these code systems, and http://snomed.info/sct is not approproptiate.
An initial proposal of http://snomed.info/srt has been made for SNOMED RT.
This page is intended to capture opinion and discussion of
- what the URIs should be
- whether SNOMED International should define/own them
- where they should be specified
- any caveats for their use (e.g. only legacy data, no new data...although it can't be enforced)
Please add your comments and thoughts below with the intent of working up a position for SI to consider.
Grahame: The FHIR community prefers a different system than http://snomed.info/sct (which is what the specification currently says), as it makes it easier to differentiate the legacy identifiers. The FHIR Community also prefers that something exist at http://snomed.info/srtc (if chosen) that is able to (a) describe what codes are valid and (b) provide some search or enumeration of all valid codes
