ENIAM: A More Complete Conceptual Schema Language

The problem of knowledge representation has been extensively addressedin the information systemsfield and there has been a wide range of suggestionsfor capturing semantics.A number of systemsand methodologieshave been proposed. Most seem to suffer from a variety of problems which makerepresentationdifficult, e.g. mixing of type and instances,too many and complex structures. Representationlanguageswhich permit a graphical form are becoming more widely acceptedunder the motivation of being ableto seethedatastructureswhich exist. However the semanticsare somewhatlimited with, for example,few integrity constraints being represented.In this paper we show how a conceptualschemalanguagewith a graphical form canbe extendedto permit a wider classof semantics to be represented.
