HELPERG Data · Provenance

Sources

Every organisation HELPERG Data reads from, the licence each dataset travels under, whether it may be redistributed, and the attribution that must accompany it.

10 registered sources from 4 organisations, rendered from the same registry the API serves at /api/v1/sources. Where terms are unclear, the conservative reading applies and nothing is redistributed.

Attribution: Weather data from MET Norway (Norwegian Meteorological Institute), licensed under CC BY 4.0.
Update frequency: Continuous. Each response carries its own Expires header, which is authoritative.

How attribution travels with the data

Every API response carries meta.attributionRecords: the source, its official URL, the licence name and URL, whether attribution is required, the exact credit line, and whether HELPERG modified the data — which it does on the calendar and weather surfaces, where provider vocabularies and units are normalised. A consumer that renders the data and drops the record is in breach of the source licence, but cannot claim it was never told.

Developers: attribution requirements in the API documentation. Records on thecalendar, releases andweather pages show their attribution beside the data.
