This paper discusses the unification of the meta-ontological model, namely, its conceptualization, in particular in library information activities. Arguments are presented that can allow us to unify the categorical declarative model of meta-ontology. The analysis is based on the categorical tensor fractal approach. These results provide an opportunity to intensify the discussion on this topic. It is declared that there is a need for not only conceptualization, but also categorization itself as the basis of the terminological dictionary of a specific subject area, branch, and field of knowledge. It is proposed to divide the ontological model into three components: (1) the categorial declarative component, (2) the production component, and/or, (3) the conceptual motivational component. © 2019, Allerton Press, Inc.
