Content and content management have become buzzwords. They are still heavily overloaded, not well understood or defined and heavily misused. Moreover, the user dimension is not yet incorporated. We develop an approach that is based on separation of concern: syntax dimension and content, semantics dimension and concepts, pragmatics dimension and topics, and finally referent or user dimension and memes. This separation of concern may increase the complexity of handling. We show, however, that a sophisticated handling of different kind of data at each dimension and a mapping facility between the dimensions provides a basis for a user-oriented content management system. This separation of concern and the special mapping procedure allows to derive content management systems that satisfy the needs of user communities.
