OKF is an open, human- and agent-friendly format for representing knowledge — the metadata, context, and curated insight that surrounds data and systems. It is designed to be authored by people, generated by agents, exchanged across organizations, and consumed by both.

The format is intentionally minimal: a directory of markdown files with YAML frontmatter. There is no schema registry, no central authority, and no required tooling. If you can cat a file, you can read OKF; if you can git clone a repo, you can ship it.
