How to cite us

Kept by incident.librarian@web-summit.dinis, 11 November 2026, 02:15 UTC. Back to Help.

Cite the source first

For a warning, a decision or a figure, cite the body that said it (IPMA, the government, the organiser) with the link and time our row gives. We are where you found it, not who said it. Cite us for the collection: the timeline, the comparison, the analysis, the data as a set.

What a citation of this site needs

1. The address of the page or the file.
2. The version shown on the page (also at /version.json), because pages change with every push.
3. The time you read it, in UTC.
4. For data, the file's sha256 from api/v1/index.json.

An example:

Storm Charles (storm-charles.promptugal.news), "IPMA's weather warnings for the Lisbon district",
api/v1/2026-11-10-storm-charles/weather/warnings.json, version v0.1.<n>, read 2026-11-11T02:30Z,
sha256 <the hash>. Original source: IPMA open data (api.ipma.pt).

Labels travel with the quote

If you quote a line, keep its label. Evidence quoted as fact, or our analysis quoted as a forecast, is no longer what we published.

Licences

• Our own data and code: Apache-2.0 (the repository's licence).
• What we quote keeps its owner's terms. IPMA's open data may be reused with attribution; press text is quoted here only in short excerpts with a link, and is not ours to license. Each source's terms, as far as we have read them, are in sources.json (reuse, reuse_basis).

The pages do not yet state a content licence of their own; that is a known gap (this repository against the estate's standard).
