Data sources and licenses
YayNo's business directory is built from open datasets. This page lists every source we use, the license it carries, and where to read the full terms. Listings imported from these datasets start unclaimed, with no reviews, and are not an endorsement of the business or of YayNo.
YayNo is not affiliated with, endorsed by, or sponsored by the Overture Maps Foundation, Meta, Microsoft, Foursquare Labs, Inc., AllThePlaces, OpenStreetMap, or any other data provider.
Overture Maps Places
The primary directory source is the Overture Maps Places theme, accessed from Overture's public S3 and Azure releases. Citation (optional, Overture attribution page): Overture Maps Foundation, overturemaps.org. Data accessed 12 November 2026. Release identifiers are stored on each imported record.
Overture Places contains no OpenStreetMap data and has none of the share-alike obligations of the ODbL. It is a multi-license dataset: each place carries a license on its sources field.

What we must do, and what we do
- CDLA-Permissive-2.0. When sharing the data, we make the agreement text available with it. There is no share-alike and no required attribution string; we credit Overture and the per-record source anyway.
- Apache 2.0 (Foursquare). We provide the license, preserve the Foursquare NOTICE in full, and state the changes and dates (Overture's schema transformation on 2026-03-18; YayNo's directory adaptation starting 12 November 2026) in NOTICE.txt. Foursquare-sourced business pages repeat the required copyright line.
- CC0 1.0 (AllThePlaces). No obligations; the text is still on file.
- Each imported row stores its Overture GERS id, the
sourcesarray (dataset and license), the release version, and a visible attribution line.
The data is provided “AS IS,” without warranty. Overture documents known quality issues (duplicates, incomplete attributes). We filter on a documented confidence threshold and skip permanently closed places and geographic features such as mountain peaks. A listing is not a claim that the business is current, complete, or recommended.
OpenStreetMap (separate import)
Some listings in this demo come from OpenStreetMap, imported by a separate pipeline (source=osm). They are © OpenStreetMap contributors and licensed under the Open Database License (ODbL) 1.0.
OSM and Overture records are never merged. If an incoming Overture place matches an existing OSM listing by name and proximity, the Overture row is skipped. Attributes are not copied across licenses. A public dump of a combined database would need legal review because of ODbL share-alike; we do not publish one. OSM-only pages keep the OSM attribution; this site is a produced work and does not require us to open-source the application.
What is ours
Reviews, Yay scores, accounts, claims, and the YayNo application are original content of Latitude 65 Technologies LLC. They are not derived from Overture or OpenStreetMap. Sample businesses used to walk through the product are labeled “demo” and are not real reviews.
