Knowledge "objects' are proposed as a modelling framework which facilitates the reuse of knowledge. Knowledgeobjects are operators which maybe used to construct the 'items' in the conceptual model. Items are a single frameworkfor describing the data, information and knowledgethings in an application. Theconceptual model is constructed by applying object operators to hasic 'data items'. Items are expressed in terms of their particular 'components'. The knowledge embedded within a knowledgeitem can not he rcadily applied in the context of diffcrcnt components. Items do not facilitate reuse. Objects are not expressed in terms of particular componentsand do facilitate reuse.
