The grouping role URI was

http://www.ihtsdo.org/RoleGroup

and is now

http://snomed.info/id/609096000

For the OWL XML representation, the URI was unspecified (the empty string), while for the OWL Functional Syntax representation the URI was (via RDF:about)

http://www.ihtsdo.org/sct.owl

and now includes explicit version information

The CTS2 specification requires that all resources be identified using URIs. This section lists, where such a thing exists, the IHTSDO standard URIs for the resources that require URIs in the CTS2 implementation. This omits URIs for things such as External Code Systems and Value Sets since they are outside the scope of the SNOMED CT URI Standard. Note, however, that a Reference Set is the SNOMED CT mechanism for identifying an arbitrary set of Concepts, which is analogous to a Value Set. Thus the Reference Set URI would be the appropriate thing to use as the Value Set identifier.

Identifying SNOMED CT Versions in HL7

...

Fast Healthcare Interoperability Resources (FHIR™)

Footnote Macro

See http://hl7.org/fhir

defines a set of 'resources' to represent health and healthcare administration-related information. Rather than OIDs, FHIR uses URIs to identify code systems, usually along with an associated version string. The code system is intended to characterise the set of valid codes, hence the recommended URI to use for this is:

http://snomed.info/sct

and the recommended string template to use for the associated version, substituting in the appropriate module sctid and effective time, is:
