Michel, I believe the difference you are seeing is because of how you reference the definition.
When you ask for http://qudt.org/2.1/vocab/unit, you get a graph with base URI of http://qudt.org/2.1/vocab/unit In that graph, unit:M specifies: rdfs:isDefinedBy <http://qudt.org/2.1/vocab/unit> ; When you ask for http://qudt.org/vocab/unit, you get "the latest version" of the graph, with base URI of http://qudt.org/vocab/unit In that graph, unit:M specifies: rdfs:isDefinedBy <http://qudt.org/2.1/vocab/unit> ; rdfs:isDefinedBy <http://qudt.org/vocab/unit> ; This is as I intended, because both statements are true, since 2.1 is the latest version at present. The QUDT 2.1 catalog at http://www.qudt.org/2.1/catalog/qudt-catalog.html is intended for a human audience, and it shows you the 2.1 version of definitions via html pages. (You can also visit earlier versions of the catalog from the QUDT homepage at http://qudt.org/) The resolvable URIs for "unit" discussed earlier in this message are intended for a machine audience, where Turtle files are delivered rather than html files. I'm open to suggestions from the community as to how this should behave if not the above. Steve On Fri, Sep 13, 2019 at 4:00 AM 'Bohms, H.M.
