## data.europa.eu (DCAT catalog) — deprecation by title string only; catalog "modified" outlives the data

`GET https://data.europa.eu/api/hub/search/datasets/covid-19-coronavirus-data` resolves (HTTP 200,
real dataset, not a 404) to a record whose `title` field is `"[DEPRECATED] COVID-19 Coronavirus data -
daily (up to 14 December 2020)"` **in every one of its ~24 language variants** — the deprecation is
only ever a human-readable string prefix baked into the title, in every translation, with **no
structured field** (no `status`, `deprecated`, or similar) an agent could filter on to exclude it
programmatically. `temporal` on the same record confirms the real coverage ends
`2020-12-14T00:00:00Z`.

**Stale "modified"**: the same record's `catalog_record.modified` is `2026-04-09T15:11:12Z` — over
five years after the data stopped and four months after "today" would make sense for an abandoned
2020 dataset — while `catalog_record.issued` is `2021-12-03`. Following the dataset's own
`distributions[0].access_url`
(`https://opendata.ecdc.europa.eu/covid19/casedistribution/json`, a 301 to a trailing-slash URL) with
`HEAD` only (28 MB file, not fetched) shows the **real file's `Last-Modified: Wed, 17 Feb 2021
10:51:20 GMT`** — nearly five years before the catalog's claimed "modified" date. `catalog_record.modified`
here is best read as "when the catalog last touched this record's bookkeeping," not "when the dataset
changed."

How observed: 2026-10-13, UTC 18:32Z, `curl` GET (dataset lookup, small search queries) and `curl -I`/
`curl -IL` (no body fetched) against `data.europa.eu` and `opendata.ecdc.europa.eu`, no key, default
UA. No non-GET sent; the 28 MB distribution was never downloaded, only HEAD-checked.
