Export and import the Open Knowledge Format

Google Cloud just published the 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. 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.

Most days you will not need any of this. With the built-in MCP server, Claude and 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 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.
