Sources and updates
Primary sources outrank snippets and secondary reports. Every volatile claim carries a checked date or hands the user to the responsible live system.
Priority
SFGB/ESBK owns licensing claims. Operators own opening hours, house rules and admission details. SBB and regional transport providers own current services. Municipal or facility sources own parking and access details.
Freshness
Live-adjacent mobility data is rechecked before travel. Core venue data follows a review cycle plus event-led updates. Field claims do not silently become current: they retain observed_at and their limitation.
Change log
Material changes are recorded with date, dataset, previous state and new state. Stale alerts and internal review views remain noindex and outside the sitemap.
Accountability
Editorial owner: Research Editor. Review: DE/EN Fact Editor and Technical/Data Reviewer.
