Creating and understanding a quality ontology requires familiarity with several core concepts. These form the foundation of how knowledge is structured, connected, and presented within a Space.

Entities are the primary objects or nodes in the knowledge graph. They represent things, people, places, concepts, or events. Each entity has a unique identity and is described by a set of properties. Entities form the backbone of the ontology.

Properties describe attributes of entities or relations. They answer questions like "What is the name of this entity?" or "When did this event occur?" Properties have:

Properties ensure knowledge is structured, searchable, and interpretable.

Relations connect two entities, expressing how they are linked. Each relation has a type or label (e.g., hosts, produced by, located in) and may have properties of its own (e.g., start date, duration). Relations are the glue that creates meaning and enables graph traversal.

A Space is a bounded context within the knowledge graph where entities, properties, and relations live. Spaces define governance, collaboration, and editorial control. They act as containers that organize knowledge without isolating it from the global graph.

The mapping between data type and renderable type ensures consistency and appropriate presentation.

Proposals are suggested additions or edits to the knowledge within a Space. They allow contributors to propose changes without immediately affecting published content. Members vote on proposals to approve or reject them, ensuring governance and quality.

Governance defines who can create, review, and publish knowledge within a Space. Editors can propose changes; members vote on proposals. Governance ensures transparency, accountability, and quality in knowledge management.
