# Knowledge graph

_How GraphCanon models tools as a connected graph instead of a flat directory - the pieces that make a graph a graph._

Key concepts: Entities, Nodes, Edges, Provenance

## Canonical

The canonical version is the single official form of something - one URL, one name, one record - that all variants and duplicates resolve to.

## Edge (relationship)

An edge is a connection between two nodes - the relationship that makes a graph a graph.

## Entity

An entity is a real-world actor in the graph - an organization or person - that tools can be linked to, such as the company that maintains a repo.

## Knowledge graph

A knowledge graph stores information as entities connected by typed relationships, so meaning lives in the connections - not just in rows of a table.

## Node

A node is a single thing in a graph - in GraphCanon, usually one tool, category, or entity.

## Provenance

Provenance is the recorded origin of a piece of data - where it came from, how it was derived, and when - so a claim can be traced and trusted.

## Taxonomy

A taxonomy is a controlled, agreed-upon set of categories used to classify things consistently, rather than free-form tags.

## Typed edge

A typed edge is a relationship with a named kind - such as alternative, integrates_with, depends_on, or successor - so the connection is precise.
