Thanks Steve, that makes sense, particularly since the qudt and units bundled in TBC are inconsistent w.r.t. class namespaces !
The bigger question is how reference data like this should be handled in TBC and EDG - in terms of expected update strategies and recommended pathways to making things visible and usable in EDG As a straw man I would be expecting/hoping for: 1) Reference data to include the current best practice per product release - either update if namespace unchanged or added with new namespace 2) Old versions kept as deprecated for a few release cycles if new version has unique namespace, with links to new namespace 3) All SHACL shapes necessary to use reference data out of the box available 4) A simple documented pathway to make reference data available in EDG and via GraphQL On Wednesday, July 1, 2020 at 2:52:39 AM UTC+10 Steve Ray wrote: > I would strongly urge you to consider migrating to QUDT version 2.1.
