One file with everything
The yearly dump carries all datasets above, the schema notes and a copy of the licence. It is rebuilt whenever a dataset gains rows:
- ravensholm-open-dump-2025.zipall CSVs + schema + licence
Current dump SHA-256, first 16 hex: bc95e0582b6bec2c… — compare with sha256sum ravensholm-open-dump-2025.zip after download.
Publication policy
Append, don't rewrite
Figures are corrected by adding flagged rows, so a number you quoted last spring stays findable. The schema file explains the correction flags.
No registration, ever
Downloads work the same for a schoolchild and a ministry. We do not gate the data, and we do not count who takes it.
Delays are honest
A late publication shows the reason on this page — a sensor fault is a sensor fault, not a silent gap.
Open licence
CC BY 4.0: use it, sell it, publish it — name the city and link a dataset. The full text ships in the yearly dump.
