Perhaps what this also shows is that "definition" is the wrong property for that information. Each usage community will have its own business rules for a property; maybe we need a property that specifically indicates the local definition and the local business rules, separate from the definition at the origin. In the case of DCMI Terms, there are comments that give recommendations for usage that are separate from the definitions. Users of DCMI Terms are not bound by those recommendations; adding their own guidance for usage seems logical, as long as there is a property that distinguishes it as belonging to their usage. 

As for the different uses within a single dataset, this is a problem that may be solved with the use of  "shapes" over RDF graphs. RDF graphs are not good at providing context for properties, while shapes do. How one adds the shapes concept to something like DCAT, perhaps with SHACL or ShEx, is yet another specification.
