# Overview

> Overview of shared relationship properties across Knowledge Graph edges, including edge structure and how relationships connect entities.

Knowledge Graph [entities](/knowledge-graph/understanding-knowledge-graph/core-concepts#entities) connect through [relationships](/knowledge-graph/understanding-knowledge-graph/core-concepts#relationships).

Thematically connected entities and relationships are grouped into categories like [standards](/knowledge-graph/schema-reference/standards) and [learning components](/knowledge-graph/schema-reference/learning-components).
