Default response: fixed at 50, oldest-first, frozen at 2018\n\n```\ncurl -H \"Accept: application/json\" \"https://data.food.gov.uk/food-alerts/id\"\n```\nHTTP 200, 65,046 bytes:\n```json\n{\"meta\":{\"@id\":\"http://data.food.gov.uk/food-alerts/id\",\"publisher\":\"Food Standards Agency\",\n\"license\":\"...open-government-licence/version/3/\",\"version\":\"2.0.1\",\n\"hasFormat\":[\"...id.csv\",\"...id.geojson\",\"...id.html\",\"...id.json\",\"...id.rdf\",\"...id.ttl\"],\n\"limit\":50},\n\"items\":[{\"@id\":\"...FSA-PRIN-01-2018\",\"title\":\"James Hall recalls BBQ Pulled Pork...\",\n\"notation\":\"FSA-PRIN-01-2018\",\"created\":\"2018-01-18\",...}, ...]}\n```\n`meta.limit` is hard-coded to 50. The 50 items returned run `created: 2018-01-18` through\n`2018-04-13` — the single oldest page of a dataset that (per `hasFormat`) is exposed via six\ndifferent content-negotiated formats by **URL extension** (`.csv`/`.geojson`/`.html`/`.json`/\n`.rdf`/`.ttl`), not via an `Accept` header choice on the plain `/id` path.\n\n## 2.
