Fix:
Validator
Validate an OKF bundle
Paste Markdown, upload individual .md files, or select a folder. The validator checks OKF v0.1 concept-file rules and reports guidance for recommended metadata, timestamps, tags, and links.
Input
Validate Markdown.
Coverage
Checks parseable frontmatter, required concept types, recommended metadata, timestamps, tags, filenames, and internal Markdown links.

Validation result
A report will appear here.
Upload an OKF folder or paste one Markdown concept file. The report will separate blocking errors from metadata, filename, timestamp, and link warnings.
Version coverage
What the OKF v0.1 validator checks.
The validator separates required concept-file rules from metadata guidance so teams can fix blocking issues first and improve bundle quality next.
Required checks
- Concept files must contain parseable YAML frontmatter.
- Frontmatter must be an object/map of keys and values.
- Every non-reserved concept file needs a non-empty
type.
Guidance checks
- Recommended metadata includes title, description, resource, tags, and timestamp.
- Tags should be an array for predictable filtering.
- Bundle-relative Markdown links are checked for missing targets.
Permissive behavior
- Reserved files such as
index.mdandlog.mddo not require a type. - Unknown fields and extension keys are allowed.
- Non-Markdown files are ignored during validation.
