Glossary of Terms of UIAM, EFOS, and PCI: A Dictionary of Ontological Entities, Physical Phenomena, and Units of Measurement
Year: 2026
Type: preprint
Abstract: The article presents a systematic glossary of terms, phenomena, and units of measurement used in four interrelated models: UIAM (Universal Information-Architectural Model, Nikita Kazachenko), IAMR (Information-Architectural Model of Reality, Andrey Zagidullin), SFOS (Entity Forming Objects and Subjects), and ICP (Projection Coherence Index). The glossary is intended to unify the conceptual apparatus and facilitate communication between researchers working at the intersection of physics, ontology, informatiology, and metrology. For each term, a definition, status, units of measurement (where applicable), and notes indicating the source are provided: Nikita Kazachenko's model, the SFOS model, the IAMR model, or joint work. The glossary is structured into sections: basic ontological entities (SFOS, IAMR, $I_\delta$, $P(G)$, $L_k$, $T_{RG}$, $\Phi$, $Z[J]$), entropy and information ($S_{total}$, $dS_I$, $dS_{local}$, $\nabla I$), the Projection Coherence Index (ICP and its components), physical objects and phenomena (entropic sink, topological glue, $W^+$), and the hierarchy of forms of matter (7FM). Particular attention is paid to divergences in the interpretation of ICP between the UIAM model (thermodynamic approach) and the SFOS model (ontological approach), which are the subject of joint verification. A section "Classification Terms" has been added with a historical note on the formation of the dominance of the physicalist interpretation of information in physics since the 1960s, with reference to a separate historiographic study by the author. It is emphasized that the terms "physicalism" and "materialism" are external classification labels, not self-designations. The glossary is open for additions and refinement. The author invites colleagues to discussion and joint work.
