… a term used in the Atlas Framework


Merriam-Webster defines concept as an idea of what something is or how it works.

Each Concept on the Atlas has its own page of description.

Terms vs concepts

Term is used in the Atlas to refer to a word or phrase for which it is useful to offer a succinct definition, but not with the amount of detailed description warranted by a word or phrase that is deemed to be a concept.

If warranted, a term can be “promoted” to a concept, in which case it appears on the Atlas in slightly different page format, most visibly including with an image.

Terms are listed with concepts in the Concepts and Terms database.

Core concepts

Core concepts are concepts that are deemed essential in the exposition of core topics. Terms that are used in the exposition of core concepts are called core terms. See Defining Core.
