Abstract | This paper addresses knowledge dimensions as units in knowledge organization (KO). Knowledge dimensions concern the ways reality is represented through a series of steps, including (α) reality in itself, (β) phenomena, (γ) perspectives, (δ) documents, (ε) collections, (ζ) information needs, (η) people, (θ) cognition. Concepts of particular perspectives, like the discipline or the viewpoint by which a phenomenon is considered, could be defined in terms of phenomena, e.g. hydrology is the study (γ) of water systems (β), or astronomy is the scientific study (γ) of celestial objects (β)The approach based on phenomena is taken in the Integrative Levels Classification (ILC), which primarily lists phenomena rather than disciplines. DDC tends to lump theory and application in a single class. Both DDC and ILC are used to represent the subjects of KOSs recorded in the Basel Register of Thesauri, Ontologies and Classifications (BARTOC). The subject of some KOSs only have dimension β with no particular γ. This is the case of the scientific taxonomies of organisms and of languages that simply list their objects, as well as taxonomies for e-commerce that simply list products. Disciplinary classifications imply both γ and β. Other KOSs are explicitly conceived for application to a particular kind of documents, such as books (δ), or a particular kind of collection (ε), such as library classifications or museum classifications. Among the KOSs which deal with educational media used in schools, document (δ) (type of educational media) or people (η) (for children or adolescent) dimensions appear. In conclusion, we were able to apply various dimensions beyond the discipline-focused dimension (γ) when we indexed KOSs in BARTOC. Also, we can find that there are various types of dimension applied according to the characteristics of the KOS.
