Specification Links

You can find the latest released draft on the Specification page. The complex numbering and naming system for drafts and meta-schemas is fully explained here as well.

Understanding draft names and numbers

IETF Internet-Drafts (I-Ds) are named with the editor's name and a sequential number which resets with each new editor. Meta-schemas were more-or-less numbered sequentially up through Draft 7, but the increasingly confusing mismatch between "draft-nn" versions on the meta-schemas and the IETF documents has made that unsustainable. The practice of fixing meta-schema bugs in place to preserve the sequential numbering has also been controversial.

Starting with what had been called "Draft 8" while it was being written, meta-schemas are identified by the year and month of publication. This allows for bug fixes to be published with new URIs (as long as it is not more than once a month).

Published Drafts


Obsolete Draft 2020-12 Documents

These were updated without changing functionality or meta-schemas due to a few errors and unclear sections.

Draft 2019-09 (formerly known as Draft 8)

NOTE: All meta-schema URIs now use https://. While currently also available over plain HTTP due to the limitations of GitHub pages and the need to keep prior drafts available over HTTP, only the HTTPS URIs should be used.

Draft 7

Obsolete Draft 7 Documents

These were updated without changing functionality or meta-schemas due to a few errors and unclear sections.

Draft 6

Draft 5

Draft 4

Draft 3

Draft 2

Draft 1

Note that Draft 0 erroneously claimed to update another RFC, and was replaced the same day by Draft 1. It is included here for completeness only.

Latest Snapshot (work in progress)

The next unreleased draft is a work in progress. You can give feedback and get involved on GitHub.

The specification links here link to the raw sources. We do not provide rendered work-in-progress drafts except near the very end of a publication cycle, during the final review period.
