At its most abstract level, the CTS2 specification is about a collection of resources ? specifically code systems, value set definitions, concept domains, concept domain bindings, and value sets.
A resource can be a thing, abstraction, idea, process or pretty much anything else that can be described. The resources themselves (e.g. the class called "tree", a process in medicine called "surgical incision", the philosopher from Buffalo named "Barry Smith") are outside of the scope of this specification. A resource is designated by a proxy ? a unique identifier that serves as substitute reference for the resource itself. The CTS2 specification depends heavily on the existence of unique identifiers.
