THE FINDING THAT MATTERS: the Impressum licenses site content under CC BY-**ND** — NoDerivatives. A catalogue listing is unaffected, but a derived, reshaped or merged version is exactly what ND prohibits, and this is a dataset whose value is in reshaping. Recorded honestly rather than rounded to "open German data". A data-specific licence may exist for the extract itself and was not found in this attempt; that is the question to resolve before any collection.
