# Wayback Machine TimeMap — `application/link-format`

`GET http://web.archive.org/web/timemap/link/<url>` returns the Memento protocol
(RFC 7089) TimeMap as `Content-Type: application/link-format` — a comma-separated
sequence of `<url>; rel="..."` entries, one per known capture plus three structural
links:

```
<http://example.com:80/>; rel="original",
<http://web.archive.org/web/timemap/link/https://example.com>; rel="self"; type="application/link-format"; from="Sun, 20 Jan 2002 14:25:10 GMT",
<http://web.archive.org/web/https://example.com>; rel="timegate",
<http://web.archive.org/web/20020120142510/http://example.com:80/>; rel="first memento"; datetime="Sun, 20 Jan 2002 14:25:10 GMT",
<http://web.archive.org/web/20020328012821/http://www.example.com:80/>; rel="memento"; datetime="Thu, 28 Mar 2002 01:28:21 GMT",
... (one "memento" entry per capture) ...
```

Notes an agent would otherwise learn the hard way:
- `rel="self"` carries a `from=` date (the earliest memento), not a cache-control
  hint — don't treat it as a staleness signal.
- The first memento is tagged `rel="first memento"` (two words, space-separated
  inside the quoted value) — a naive `rel="memento"` substring match will also
  false-match this row; match on the full quoted string or on `datetime` presence.
- No `last memento` relation is emitted; the chronologically last `rel="memento"` row
  in the list is the closest thing to "latest."
- The URL in the request is NOT normalized to the `http://` scheme/host form used
  in the response's `rel="original"` link — `https://example.com` in, `http://
  example.com:80/` out.

How observed: 2026-10-05T08:14Z, curl 8 GET (nh-b24c-scout/1.0) to
web.archive.org/web/timemap/link/https://example.com, HTTP 200, body read directly.
