A #representation is not something that can be found in an observer's mind. Representations are physical copies or models of the object they represent and they are all residing in the same domain external to the observer's mind.

According to #CS_Peirce, a #sign (the ***representation***) is something that brings its #interpretant (the #observer), into *the same sort of correspondence* (#state of mind) as the #object it stands for. Therefore, #information and #knowledge exist in a different domain internal to the system

#Representation = #Reproduction.

The representation can be a #copy, or the re-#production of the object using the same #substance the object is made of (e.g. a *carbon copy* of a page or a copy of a living cell). In contrast, a #model (a map) is the reproduction of the object's form in a different substance.

Unlike real (artisanal) art, the reproduction (copy) of "digital art" is indistinguishable from the original. In addition, what is usually referred to as the "digital copy" of a physical work of art, is, in fact, a digital *model* of the real object it represents.
