# Context Graphs

> The backbone of Galaxy

## **What is a Context Graph?**

A **Context Graph** is an ontology-driven knowledge graph. It connects meaning across databases, teams, tools, and time.

## **What Context Graphs Enable**

Context graphs help teams:

* Understand relationships across system boundaries
* Traverse information the way humans naturally reason
* Preserve nuance that flat schemas and static docs lose

## **Capabilities of the Graph in Galaxy**

The graph you build in Galaxy is:

<Columns cols={2}>
  <Card icon="check-double" horizontal title="Navigable">
    Explore connections interactively
  </Card>

  <Card icon="check-double" horizontal title="Visual">
    See relationships at a glance
  </Card>
</Columns>

<Columns cols={2}>
  <Card icon="check-double" horizontal title="Queryable">
    Ask questions and get answers
  </Card>

  <Card icon="check-double" horizontal title="Evolvable">
    Automatically up-to-date
  </Card>
</Columns>

This is why Galaxy is not only “semantic modeling.” The graph is how meaning becomes usable in practice.

## **Context Graphs in Our Product**

We represent context graphs as [Projects](/projects) in Galaxy. Projects are created from Sources and consist of nodes and edges. You can ask questions on top of your Project using our Chat feature. Read more about each of these components:
