Open Knowledge Format · v0.1 conformance

OKF Validator

Paste one concept file or upload a bundle. Checks the three hard rules (parseable frontmatter, non-empty type, reserved-file handling) and flags quality issues the spec tolerates as warnings.

Note: The "Paste" option of this tool assumes that you copied the text from a Markdown (.md) file. If you are unsure, please use the file upload option.

Drop .md files here

Multiple files or a whole bundle folder. Non-markdown files are ignored.

What conformance means here

OKF v0.1 is intentionally lenient. A file fails only when it breaks a hard rule. Everything else is reported as a warning so you fix blocking issues first, then improve quality.

Errors (fail): missing or unparseable YAML frontmatter; frontmatter that is not a map; missing or empty type on a non-reserved file.
Warnings (still conformant): missing recommended fields (title, description, resource, tags, timestamp), tags not an array, broken bundle-relative links, empty body.
Reserved files (index.md, log.md) do not require a type. Unknown fields and unknown type values are allowed.
