Reference policy

How sources are used on this site.

01

Start with primary evidence

Specification claims link to the official draft and commit history. Adoption claims link to original repositories, commits, issues, or maintainer announcements.

02

Separate rules from recommendations

Merged specification rules are documented separately from open proposals, metadata quality guidance, link portability, and implementation profiles.

03

Record verification dates

The draft and ecosystem can change quickly. Status pages state when evidence was checked so readers can distinguish a snapshot from a timeless rule.

Improve the reference set

Submit a useful OKF source.

Send a reference, example bundle, integration note, article, validator, or template that helps builders understand and use OKF.
