Open Knowledge Format v0.1 (Google Cloud, June 2026) represents knowledge as a directory of UTF-8 Markdown files with YAML frontmatter. No manifest, no schema registry, no required tooling. One file = one concept; the graph is built from ordinary Markdown links between files.
- A concept's id is its file path minus
.md. - Frontmatter carries the metadata — see frontmatter schema.
- Reserved filenames:
index.md(a directory's table of contents) andlog.md(change history). This bundle uses both. - Links are absolute (
/x/y.md) or relative (../y.md) and are untyped.
okfview implements this format faithfully — and only this format, by
deliberate scope. The full rules okfview enforces are in
conformance, and okfview serves this same reference to agents via
the get_okf_spec MCP tool.
