# Extension Views

> Specialized components for rendering specific EAA extension data.

> Each extension view renders a structured display of its corresponding `ext:namespace@version` data object. Import only what you need.

```tsx theme={"theme":{"light":"github-dark","dark":"github-dark"}}
import {
  AIExtensionView,
  LicenseExtensionView,
  OnchainExtensionView,
  VerificationView,
  ContribExtensionView,
} from "@provenancekit/ui";

// Renders ext:ai@1.0.0 data — model, provider, autonomy level, tokens
<AIExtensionView data={action.extensions["ext:ai@1.0.0"]} />

// Renders ext:license@1.0.0 — SPDX ID, AI training status
<LicenseExtensionView data={resource.extensions["ext:license@1.0.0"]} />

// Renders ext:onchain@1.0.0 — tx hash, chain, contract
<OnchainExtensionView data={action.extensions["ext:onchain@1.0.0"]} />

// Renders Ed25519/ECDSA signature verification result
<VerificationView proof={action.proof} />

// Renders ext:contribution@1.0.0 — attribution weights as bars
<ContribExtensionView data={action.extensions["ext:contribution@1.0.0"]} />
