Open Knowledge Format (OKF)

OKF is a vendor-neutral, open spec (v0.2, released by Google Cloud) for representing knowledge as a directory of markdown files with YAML frontmatter. No SDK required — if you can cat a file, you can read OKF.

It formalizes the "LLM Wiki" pattern (Karpathy's gist) into an interoperable format: wikis written by different producers can be consumed by different agents without translation.

v0.2 adds: provenance tracking (sources), trust signals (generated, verified), lifecycle management (status, stale_after), and Attested Computations — a new concept type for sanctioned, verifiable calculations.

For the full spec, see:

• references/spec-v01.md — Legacy version (v0.1)

Design Principles

1. Minimally opinionated — Only type is required. The spec defines interoperability surface, not content model.
2. Producer/consumer independence — Who writes and who reads are decoupled. Human-authored bundles feed agents; LLM-generated bundles are browsed by humans.
3. Format, not platform — No cloud, SDK, or vendor dependency. Value comes from how many parties speak it.
4. Trust is first-class — v0.2 makes provenance, verification, and freshness queryable from frontmatter.
