Thank you for contributing a license to Träwelling! We'll review your pull request soon.

Here's our internal review checklist:

License requirements

• The license allows use, redistribution, and modification of the data
• The license does not require royalties or usage fees
• The license is not specific to a product or technology
• Any restrictions are clearly stated

Technical checks

• The source filename matches exactly what appears on traewelling.de/debug/motis-sources
• The data source URL is reachable and correct (or null and not relevant)

Thanks for the addition. :)

However, for generic SPDX licenses, I would recommend adding that directly to Transitous; then we wouldn't need the entry here, because Träwelling can process it automatically.

I've added the identifiers to transitous here: public-transport/transitous#2113
