Ontological concepts

Types of concepts, symbols, special characters, plain-text prefixes

Types of concepts

Ontological concepts classify the kinds of entities used in ontology modeling (classes, particulars, properties, relators, etc.). Each kind can carry a graphic symbol and special characters that support readable formulae; plain-text prefixes make the same ideas usable in URLs and ASCII-only serializations (typors on taoke.de).

[GuBe2021] and [AlHe2020] connect this discipline to foundational ontology practice and OWL-oriented engineering.

OntoGraphs and notation

Graphical visualization (OntoGraphs) reuses these symbols so diagrams stay aligned with triple-level syntax.
