# Data licenses

Every shipped dataset, its source, its licence and the attribution it asks for. A
`data-import/` script rebuilds each sourced table; a curated one is hand-written.
The scripts run through `docker compose run --rm data-import data-import/<name>.py`
and cache their downloads under `data-import/cache/`; `geo-se.py` needs a
Trafikverket API key, free at [data.trafikverket.se](https://data.trafikverket.se/),
in `TRAFIKVERKET_API_KEY` or a `--key-file`.
