City, Gdańsk vs City, New York Open Data
Otwarty Gdańsk (Open Gdańsk) runs a standard CKAN 2.x installation; a live keyless GET against `ckan.multimediagdansk.pl/api/3/action/package_search` returned full JSON dataset metadata with a wildcard `Access-Control-Allow-Origin` header on both the plain response and an OPTIONS preflight. The catalogue covers Gdańsk municipal transit, budget, and environmental datasets, with individual resources downloadable as CSV, JSON, or XLSX depending on the publisher.
NYC Open Data runs on Socrata; a live keyless GET against the SODA endpoint for the 311 service-request dataset (`data.cityofnewyork.us/resource/erm2-nwe9.json`) returned full JSON with a wildcard `Access-Control-Allow-Origin` header, and the same resource is fetchable as CSV by swapping the file extension. Anonymous reads work without any credential; registering a free Socrata app token is optional and only raises the per-IP throttling limit.
