This file preserves attribution notices required by upstream licenses.

-------------------------------------------------------
The following is the complete content of Foursquare's NOTICE.txt
(https://fsq-os-places-us-east-1.s3.amazonaws.com/NOTICE.txt),
which Apache 2.0 and Foursquare's notice require us to preserve:

The Foursquare OS Places dataset (the “Data”) is licensed under the Apache License, Version 2.0 (the "License"). You may not use, modify, or distribute the Data except in compliance with the License.

As set forth more fully in the License, if you use, modify, or distribute the Data, you must:
* provide recipients with a copy of the License.
* if applicable, include prominent notices to the extent you’ve changed the Data.
* preserve attribution to Foursquare, including preserving the full content of this NOTICE.txt file.

To ensure appropriate attribution to Foursquare, we recommend the following:
* if using/distributing the Data in flat file form as-is or after making changes/modifications: include this NOTICE.txt file, which may be modified to include an additional notice of your changes/modifications, if any.

2. Overture Maps Foundation — Foursquare transformation notice
--------------------------------------------------------------
As stated on https://docs.overturemaps.org/attribution/ (Places section)
and https://docs.overturemaps.org/blog/2025/09/24/release-notes/:

  Data from Foursquare. Copyright 2024 Foursquare Labs, Inc. All rights reserved.
  Available under Apache 2.0. Foursquare data was transformed to the Overture
  schema. Changed: 2026-03-18.


3. YayNo (Latitude 65 Technologies LLC) — further changes
---------------------------------------------------------
YayNo further adapted Overture Places records for its business directory,
starting 12 November 2026:

  - Filtered by region / bounding box and by a documented confidence threshold.
  - Flattened name, address, phone, website, and sources fields into the YayNo
    schema, retaining the Overture GERS id, per-record sources, license, and
    release version.
  - Mapped Overture taxonomy / basic_category values onto YayNo's industry and
    category slugs. The original Overture categories are stored with the record.
  - Deduplicated against existing YayNo listings by normalized name and
    proximity. OpenStreetMap (ODbL) records are never merged with Overture
    records; a name-and-proximity match skips the incoming Overture row so the
    two licensed datasets stay separate.
  - Did not modify the upstream GeoParquet files.

These changes apply to the YayNo directory database, not to a redistributed
copy of the raw Overture release.
