Deontology vs. Ontology — What's the Difference?

Ethical or moral theory concerned with duties and rights.

Ontology is the branch of philosophy that studies concepts such as existence, being, becoming, and reality. It includes the questions of how entities are grouped into basic categories and which of these entities exist on the most fundamental level.

The doctrine that ethical status of an action lies in its adherence to a set of rules.

The branch of metaphysics that deals with the nature of being.

(ethics) Ethics.

(Computers) A system for naming, classifying, and defining objects.

(ethics) The normative ethical position that judges the morality of an action based on the action's adherence to rules or obligations rather than either the inherent goodness or the consequences of those actions.

The branch of metaphysics that addresses the nature or essential characteristics of being and of things that exist; the study of being qua being.

The science which relates to duty or moral obligation.

In a subject view, or a world view, the set of conceptual or material things or classes of things that are recognised as existing, or are assumed to exist in context, and their interrelations; in a body of theory, the ontology comprises the domain of discourse, the things that are defined as existing, together with whatever emerges from their mutual implications.

The theory of a particular philosopher or school of thought concerning the fundamental types of entity in the universe.

(logic) A logical system involving theory of classes, developed by Stanislaw Lesniewski (1886-1939).

A structure of concepts or entities within a domain, organized by relationships; a system model.

That department of the science of metaphysics which investigates and explains the nature and essential properties and relations of all beings, as such, or the principles and causes of being.

A systematic arrangement of all of the important categories of objects or concepts which exist in some field of discourse, showing the relations between them. When complete, an ontology is a categorization of all of the concepts in some field of knowledge, including the objects and all of the properties, relations, and functions needed to define the objects and specify their actions. A simplified ontology may contain only a hierarchical classification (a taxonomy) showing the type subsumption relations between concepts in the field of discourse. An ontology may be visualized as an abstract graph with nodes and labeled arcs representing the objects and relations.

The metaphysical study of the nature of being and existence
