[Application-profiles-ig] Our element definitions

Ah, got it! yes, the entity is a class or type or category of things, not an individual. You gave this: "Entity": A metadata construct similar to a class or object type which may form part of a description that conforms to the application profile." We may need to word it a bit less in terms of code-like concepts (e.g. "object type") - maybe add something like "the thing or concept being described." But I like the precision of your definition. As for base specification, that's being used in the DXWG work [1]. That group has struggled with "specification" v. "vocabulary" v. "ontology" as again we don't have settled terms for this, and it seems to depend on the circumstance. I think it would be worth trying to write this up in plain wording to figure out first what we *mean* and then go on to the word-smithing. We probably will need to define a lot of terms for ourselves and our audience in order to reach clarity. I'll see if I can get something started. kc [1]https://www.w3.org/TR/dx-prof/#Class:ProfileOn 3/20/20 7:39 AM, Phil Barker wrote: >Sorry that I am not making myself clear.
