data model

Chrome DevTools for ontologies.

GraphOntology does not define ontology. It makes ontology understandable. Layouts place nodes; modes decide which relationships to emphasize; plugins add domain features.

Copy the pattern from a working story.

Web4 authority and provenance

A visitor can trace who asserts authority, what delegates it, and which evidence supports the claim.

Open graph Open report

CanonLink agreement graph

A visitor can inspect an agreement relationship without any CanonLink-specific UI living inside the core package.

Open graph Open report

Valgraf and Incentivis value graph

A visitor can see how value and evidence move through a mission system instead of reading an opaque score.

minimal host contract

Embed the explorer with app-neutral props.

A host app owns its graph, theme, permissions, and inspector copy. The reusable package owns rendering, filtering, selection, focus, export, and URL-state primitives.

import { OntologyGraphExplorer, createOntologyGraphTheme } from "@graphontology/ontology-graph-explorer";

const hostContract = {
  graph,
  theme: createOntologyGraphTheme({ mode: "dark" }),
  mode: "authority-chain",
  initialFocusId: "authority-registry",
  allowedNodeTypes: ["system", "agent", "registry", "legal", "evidence"],
  allowedEdgeTypes: ["authority", "delegates", "provenance", "registry"],
  inspectorRenderer: undefined,
  onSelect: (selection) => console.log(selection),
  onExport: (payload) => console.log(payload)
};

export function HostOntologyView() {
  return <OntologyGraphExplorer {...hostContract} syncUrlState={false} />;
}

package exports

Reusable component surface

Public explorer routes use URL state by default. Embedded hosts can pass `syncUrlState=` while still using diagnostics, algorithms, adapters, plugins, reports, and exporters from the package root.

What GraphOntology deliberately does not do.

Does not become another graph database.

Does not become another ontology language.

Does not replace JSOntology or CanonLink.

Does not execute agents.

Does not own runtime state.

Does not hide host permissions or data access.
