cims:stereotype: string vs URL

[VladimirAlexiev]

Some cims:stereotype values are strings (eg enum, others are URLs (eg uml:atribute).

Note: I defined this prefix to shorten URLs that appear in cims:stereotype: "uml": "http://iec.ch/TC57/NonStandard/UML#"

This is not wrong per se, but is slightly bad style. It makes for this ugly piece in the JSONLD ontology (eu:OperationalLimitType.kind):

      "cims:stereotype": [
        "European",
        {
          "@id": "uml:attribute"
        }
      ],

Compare to this other piece of metadata that is rendered nicely:

      "cims:multiplicity": "cims:M:1..1",

It's because I declare in the context:

  "cims:multiplicity"      : {"@type": "@id"},

But I can't do that for cims:stereotype because it has mixed values

I think we need to improve here. This is a discussion item. Ideally

• a stereotype is not a URI/URL
• for multiplicity I would prefer to split lowerBound/UpperBound kind of notation like in SHACL minCount, maxCount
