Open data and sources

This download contains only the exportable ODbL dataset: it can be downloaded, reused and corrected by anyone, without an account or asking us. Partner businesses and local services may appear in the guide as proprietary data, but do not come from OpenStreetMap and are not in this ODbL file.

Download

Download the dataset (JSON)

It contains 1060 points in the ODbL collection. The 37 records excluded from this file include proprietary partner and local-service data, and sources without a compatible redistribution licence. The 10 reported broken are included, each carrying its state and the date it was reported: a dataset that hides the broken fountains is less useful to whoever reuses it. The 21 whose only source is fontanelle.org are on the map with attribution but outside this file.

Licence

The derived database is Open Database License (ODbL) 1.0. You may use, modify and redistribute it. You must attribute OpenStreetMap where applicable and release any derived database under the same licence.

882 records contain OpenStreetMap data, under ODbL 1.0 with attribution to © OpenStreetMap contributors.

180 records contain Wikidata data, under CC0 1.0; they are not attributed to OpenStreetMap.

Partner-business and local-service details are not included and are not ODbL: they are proprietary data, merged only in memory when the page is built. Appearing in the guide does not put a business’s name under share-alike.

What this file contains

How fresh it is

Freshness is computed point by point, on that point’s own check date — never on the most recent date in the dataset.

What “verified” means here

A point is verified in one of two ways, and these are two distinct levels: somebody has checked its declared source, or gone on site. 974 points are confirmed from their source, 76 from an on-site check. We never write a source check as a visit. The 10 reported broken carry the report date and author. Dates are always the real ones, even when old.

Sources

From sources without a declared licence we take single facts, and those points are on the map. The author and the date travel with each one and are in the file above. What we do not do is redistribute their set: the 21 points whose only source is fontanelle.org stay out of the download. Datasets with a non-commercial clause are excluded entirely: perdiqua Pisa is published by a company.

What we give back

When a correction is verified on site, our method is to publish it on OpenStreetMap with the check date, so anyone can use it — including us. Until that happens, it remains a source check and is never presented as our fieldwork.

If the project closes, corrections already published on OpenStreetMap stay there with their dates. The public work that has actually been returned does not disappear with the guide.

Found a mistake?

The “Works? No” button is the fastest way to tell us: it is on everything that can break, namely fountains, toilets, study spaces, parks and useful services. It is not on the 229 monuments: asking whether a fifteenth-century square still works would tell no one anything. You can also correct the point directly on OpenStreetMap: the correction reaches us too, at the next import.
