# Export and import the Open Knowledge Format

Google Cloud just published the [Open Knowledge Format](/docs/open-knowledge-format): a folder of Markdown files, a little structure at the top of each one, links between them, an index for navigation, and a log for history. It is a common shape for knowledge that AI agents can read. It is also, almost field for field, what Hjarni already is.

So we shipped the button. **Export a folder you own, a team space, or your entire knowledge base as an OKF bundle.**

## What lands in the bundle

- **One Markdown file per note**, with OKF front-matter: title, timestamp, description, resource, tags.
- **An `index.md` for every folder**, carrying the folder's description and AI instructions plus links to its notes and sub-folders.
- **A root `index.md` and a `log.md`** change history, built from your note versions.
- **Wiki-links rewritten as relative Markdown links**, so the graph still works on disk.
- **Attachments** alongside their note.

Unzip it and it makes sense without Hjarni anywhere in the picture. Put it in a git repo, hand it to another OKF-aware tool, or point your own scripts at it.

## It reads both ways

The same bundle [imports back into Hjarni](/docs/import). Relative links reconnect, `description` and `resource` map to summary and source URL, and the `index.md` and `log.md` navigation files are skipped. This works for any OKF producer, not just bundles Hjarni made, so bringing an existing knowledge base in is as easy as taking yours out.

## Where to find it

Open your **folders** page, a single folder, or a team, then click **Export** and pick **Open Knowledge Format**. Prefer Hjarni's own front-matter? Choose **Markdown** from the same menu. To import, head to **Import** on your Personal page or [`/import/new`](/import/new).

Most days you will not need any of this. With the built-in MCP server, [Claude](/docs/claude) and [ChatGPT](/docs/chatgpt) read and write the same notes live. Export is there for the day you want your knowledge to travel. That is what [export and ownership](/docs/export-and-ownership) means: not a panic button you press when you leave, but proof that the knowledge was always yours.

Live for everyone. Nothing to turn on.
