Trying to find a name for the new element that is precise and intuitive for a broad audience of adopters is a honorable attempt. Being "right" does not buy anything here, since beautiful specifications do not ensure correct usage in a largely distributed system as the WWW. And the proposed names are more reasonable than what you make out of it.

Why? The URI of the concept is just a name. Beneath the hood, it remains possible to link this to SKOS with ease.

Surely not in the sense of owl:Class. One can work with the notion of a concept without a the notion of something being an instance of that.

I've seen this create serious communication and methodology problems when folks whose only ontology training or experience comes from such communities join ontology / semantic technology projects in other domains without managerial attention to this and other community-specialized practices.

How popular are these compared to the regular use of Concept (as in SKOS). Isn't that a caveat that there "related communities" are aware of and could live with?

For example, there are kinds of Knowledge Representation systems where Concept is the equivalent of what is called 'Resource' in RDF. I absolutely want it as a universal type, I am just worried about folks in related communities misunderstanding it.

Keep http://schema.org/Concept in case we want to have a generic 'Concept' type later? What's making this proposal too Skos specific that it cannot fulfill the generic type of 'Concept'? Why not just tell people to use skos:Concept then (from the skos namespace)?

I think it would make it confusing and require people to have knowledge about the origin vocabulary where the term came from, which goes agasint the goals of schema.org (might as well just use the original term namespace). Also, namespacing terms isn't something that has been done before in schema.org.
