has part is concretized as information content entity relational information display An information content entity that displays relations between sets in a concretized collection of display components. Zhang J. A representational analysis of relational information displays. International Journal of Human-Computer Studies. 1996 Jul 1;45(1):59–74. Zhang’s notion of 'dimension' relies on an understanding of ‘distributed representations’ which have both an 'internal' and an 'external' component. Each sets (see 'representing sets') has a quality of 'being distrobuted between internal (the cognition and representation of the sets as such) and external (the 'mark).' See: Zhang J, Norman DA. Representations in distributed cognitive tasks. Cognitive Science. 1994 Jan 1;18(1):87–122. relational information display component mark collection
