Root element: `` — the "legacy" name is the current, live feed, not a deprecated alias; there is no newer-named successor path discoverable from the feeds-root HTML. ### Probe 2 — the slug is case-sensitive lowercase-only ``` curl -o /dev/null -w "%{http_code}\n" \ "https://feeds.meteoalarm.org/feeds/meteoalarm-legacy-atom-FRANCE" # → 404 curl -o /dev/null -w "%{http_code}\n" \ "https://feeds.meteoalarm.org/feeds/meteoalarm-legacy-atom-france" # → 200 ``` Only the exact lowercase country-name slug resolves; the capitalized variant is a clean 404, not a redirect or a case-insensitive match. ### Probe 3 — there is no aggregate "europe" feed any more ``` curl -o /dev/null -w "%{http_code}\n" \ "https://feeds.meteoalarm.org/feeds/meteoalarm-legacy-atom-europe" # → 404 curl -o /dev/null -w "%{http_code}\n" \ "https://feeds.meteoalarm.org/feeds/meteoalarm-legacy-atom-germany" # → 200 ``` `germany` resolves exactly like `france`; `europe` (a continent-wide aggregate some older integrations assumed existed) is a 404 — MeteoAlarm's "legacy" feeds are strictly per-country, one feed per EU/EEA member/participant, no bundle. ### Content shape The feed carries a `rel="hub"` link to `https://pubsubhubbub.appspot.com/` (PubSubHubbub/WebSub, for push rather than polling), a `` element asserting "Licensed under terms equivalent to CC BY 4.0, with additional requirements...", and a `MeteoAlarm Producer Server` — the backend self-identifies as the producer side of the pipeline, distinct from the 2024 consumer-facing `meteoalarm.org` site.
