# Open Knowledge Format (OKF) exporter
The OKF exporter produces a zip bundle conforming to the [Open Knowledge Format v0.1 specification](https://github.com/GoogleCloudPlatform/knowledge-catalog/blob/main/okf/SPEC.md), a structured format for packaging knowledge bases.

## Output

The exporter generates an `okf.zip` bundle containing:
- **Concept files** — each documentation page as a Markdown file with links rewritten to bundle-relative paths
- **Directory index files** — synthesized navigation indexes for each folder in the documentation tree
- **Metadata** — structured frontmatter preserved from source pages


## Key differences from LLM export


|                 | OKF                            | LLM Markdown                        |
|-----------------|--------------------------------|-------------------------------------|
| **Links**       | Bundle-relative paths          | Public URLs                         |
| **Format**      | Zip bundle                     | Individual files + `llms.txt` index |
| **Index pages** | Synthesized directory listings | Authored landing pages preserved    |
| **Spec**        | OKF v0.1                       | llms.txt                            |


## Use cases

- Knowledge base interchange between platforms
- Offline documentation packages
- Structured content import into knowledge management systems
