# osinfo-db (libosinfo): default branch is `main`, files are `.xml.in`

`osinfo-db` is the libvirt/virt-install project's database of OS
metadata (install media detection, minimum resources, EOL dates),
hosted on GitLab and consumed by `osinfo-db-tools` as a downloadable
tarball, but also readable file-by-file over plain HTTPS.

## Probe 1 — guessing the obvious raw path (fails)

```
curl -sD - https://gitlab.com/libosinfo/osinfo-db/-/raw/master/data/os/ubuntu.com/ubuntu-24.04.xml
```

## Observed

HTTP 404 (GitLab's own styled HTML 404 page, `content-type: text/html`).
Two assumptions in the obvious URL are both wrong: `curl -s
"https://gitlab.com/api/v4/projects/libosinfo%2Fosinfo-db"` shows
`"default_branch": "main"`, not `master`; and the project's repository
tree (`GET .../repository/tree?path=data%2Fos%2Fubuntu.com`) shows every
file under `data/os/<vendor>/` carries a trailing **`.xml.in`**
extension (e.g. `ubuntu-24.04.xml.in`, `ubuntu-26.04.xml.in`), not plain
`.xml` — `.xml.in` is the autotools convention these files use at
authoring time, and it survives all the way into the published repo
tree rather than being an artifact that only exists post-build.

## Probe 2 — the correct path

```
curl -sD - https://gitlab.com/libosinfo/osinfo-db/-/raw/main/data/os/ubuntu.com/ubuntu-24.04.xml.in
```

## Observed

HTTP 200, `content-type: text/plain; charset=utf-8`, 6,298 bytes,
`cache-control: max-age=60, public, must-revalidate,
stale-while-revalidate=60, stale-if-error=300, s-maxage=60` (fronted by
Cloudflare, `cf-cache-status: REVALIDATED`). Body is the libosinfo XML
schema: `<os id="http://ubuntu.com/ubuntu/24.04">` with `<short-id>`
(two values: `ubuntu24.04` and `ubuntunoble`), `<codename>Noble
Numbat</codename>`, `<release-date>2024-04-25</release-date>`,
`<eol-date>2034-04-25</eol-date>`, and `<resources arch="all">` giving
minimum/recommended CPU (Hz)/RAM/storage (bytes) for installers that
consult this database.

## How observed

2026-10-05T11:47:28Z–11:47:48Z UTC, `curl` GET against `gitlab.com`
(both the raw-file path and the public `api/v4` project/tree endpoints,
unauthenticated).
