Conceptual Modeling in the eXtreme

Information and Software Technology, 2002
Abstract Conceptual Modeling-based methods and their corresponding CASE tools have traditionally had one main weak point: the use of different notations for the problem space system view (centered on the what the system is) and the solution space view (centered on the how it is to be represented).

Levels for Conceptual Modeling [PDF]

open access: possible, 2011
Usually object types are organized in taxonomies by means of a specialization relation (also called subtyping or isa) 'implemented' by means of inheritance. This paper proposes a (non-incompatible) alternative to taxonomies that relies on three primitives: grounding, a specific kind of factual existential dependence, extensional atemporal parthood, and

Since the modeling process is characterized by interpretation and abstracting the situation at hand it is essential to enclose information about the design process the modelers went through. This aspect is often discarded.
