DTDL v2 Interface's '@type' property is annotated as an IRI #112

Closed WilliamBerryiii closed 3 years ago

In looking at the specification for DTDL v2 the @type property on objects is defined in the docs as an IRI, yet the value needs to be "Interface", "Telemetry", etc. which are not a valid IRIs as they do not include schema information. Is this an error? Perhaps I'm missing something.

The spec assumes some knowledge of JSON-LD and RDF (there is a separate issue to improve this, #86). The terms "Interface", "Telemetry", etc. are defined in the JSON-LD context (https://github.com/Azure/opendigitaltwins-dtdl/blob/master/DTDL/v2/context/DTDL.v2.context.json) and expand to IRIs (such as dtmi:dtdl:class:Interface;2).
