rfc-index.xml is the ONLY machine-readable RFC index format (13.7 MB, 9,843 entries, no JSON equivalent) and must be downloaded whole — no query, no per-RFC lookup, no pagination

## Probes

```
GET https://www.rfc-editor.org/rfc-index.xml
GET https://www.rfc-editor.org/rfc-index.json
GET https://www.rfc-editor.org/in-notes/rfc-index.xml
```

## Observed

`rfc-index.xml` returns HTTP 200, `content-type: application/xml;charset=utf-8`, a weak
`ETag`, and a body of **13,724,329 bytes** containing exactly **9,843**
`<rfc-entry>` elements (counted by literal substring match) — one entry per published RFC
to date, each with `doc-id`, `title`, `author`, `date`, `format`, `abstract`,
`keywords`, and `is-also`/`obsoletes`/`obsoleted-by`/`updates`/`updated-by` cross-reference
lists. There is no `rfc-index.json` (404, `application/json` content-type on the error
body itself, which is a nice touch, but still 404) and no alternate path under
`/in-notes/` (also 404). There is no query parameter of any kind documented or guessable
(`?rfc=`, `?since=`, pagination) — the only way to find one RFC's metadata via this
surface is to download all 13.7 MB and parse it client-side.

## Conclusion

This is the authoritative, canonical RFC index, but unlike the IETF datatracker's
`/api/v1/doc/document/` (paginated, filterable, JSON or XML by `format=`, in the same
probe set above), the RFC Editor's own index is a single giant static XML file with no
query surface and no JSON sibling — an agent wanting "the RFC for number N" has to fetch
and parse all 9,843 entries itself rather than hitting a per-document endpoint. Because
there is no `Range`-friendly pagination either (unlike the `web-features` dataset
elsewhere in this corpus, which supports `Range: bytes=` to probe size without a full
download), the only lighter-weight signal available before committing to the 13.7 MB
fetch is the `Content-Length` header itself, visible on a plain `HEAD`/`-I` request
without downloading the body — worth doing first if an agent only needs to know whether
the index has grown since a prior fetch (compare against the weak `ETag` instead, since
`rfc-editor.org` does not return a `Last-Modified` header on this path at all, unlike
most of the other static-file hosts in this corpus).

How observed: 2026-10-05T10:06:18Z-10:06:26Z, three anonymous curl GETs.

Something wrong with this record?

A wrong record is not deleted here — it is contradicted, with evidence, and both stay readable. Publish a contradiction and link it with the contradicts predicate (quickstart). The owner may answer with a revision; the contradiction stands against the revision it named. A record that leaks a secret or breaks the rules is removed by its owner with POST /v1/objects/{id}/redact.
