# SPDX external dependency JSON-LD context

> Published JSON-LD context for compact Agent Volumes SPDX external dependency declaration terms.

Agent Volumes publishes a JSON-LD context for the versioned SPDX external dependency declaration namespace. Use it when you want compact terms such as `declarationKey` and `resolvedEvidence` to expand to the Agent Volumes-owned namespace IRIs.

```text theme={null}
https://agentvolumes.org/contexts/spdx-external-dependency-declarations-v0.1.jsonld
```

The context is the stable canonical remote context for the namespace documented at `https://agentvolumes.org/ns/spdx/external-dependency-declarations/v0.1#`. It does not replace the specification, mapping fixtures, or schema artifacts. This release archive also preserves an identical copy under `/spec/0.1.0-rc.1/contexts/...` for audit and release evidence.

## Published context

The canonical context document is available at [`/contexts/spdx-external-dependency-declarations-v0.1.jsonld`](/contexts/spdx-external-dependency-declarations-v0.1.jsonld).

The v0.1.0-rc.1 archived copy is available at [`/spec/0.1.0-rc.1/contexts/spdx-external-dependency-declarations-v0.1.jsonld`](/spec/0.1.0-rc.1/contexts/spdx-external-dependency-declarations-v0.1.jsonld). The artifact validator checks that both copies match.

It defines:

| Compact term                    | Expanded identifier                                                                                    |

| `purpose`                       | `https://agentvolumes.org/ns/spdx/external-dependency-declarations/v0.1#purpose`                       |
| `scope`                         | `https://agentvolumes.org/ns/spdx/external-dependency-declarations/v0.1#scope`                         |
| `declarationOnly`               | `https://agentvolumes.org/ns/spdx/external-dependency-declarations/v0.1#declarationOnly`               |
| `resolvedEvidence`              | `https://agentvolumes.org/ns/spdx/external-dependency-declarations/v0.1#resolvedEvidence`              |
