Data & credits
Atsumia is built entirely on open geographic and encyclopaedic data. Here is exactly what comes from where.
Four sources, one card
- GeoNames
- The canonical catalogue: what a place is, where it is, and its stable identifier. Licensed CC BY 4.0.
- Wikidata
- Structured enrichment and the bridge to Wikipedia and Commons. Structured data is CC0.
- Wikipedia pageviews
- The popularity signal that determines rarity. Aggregated across language editions.
- Wikimedia Commons
- Card imagery. Every file carries its own licence, fetched and displayed per file.
What this build actually contains
This is a local-first prototype of the gameplay loop. The catalogue is a development fixture of 113 real places chosen to exercise every rarity tier, several continents and the awkward cases — a place with no Wikidata link, a place with Wikidata but no English article, and two different places called Paris. The eligibility policy (v1) rejected 4 records on the way in.
Identifiers and pageview totals in the fixture are representative values, and every card says so on its detail page. Card imagery and image licences, by contrast, are fetched live from Wikipedia and Commons, so the attribution you see is real.
What a production build still needs
- A GeoNames bulk import of
allCountriesplus the daily modification and deletion feeds. - Wikidata enrichment via the
wkdtbridge, run from dumps rather than per-record API calls. - Pageview aggregation from the hourly dumps, not one HTTP request per article.
- A server-side, transactional pack draw with real idempotency keys and authenticated accounts.
- A database. Progress here lives in your browser and nowhere else.
Image licensing
Commons hosts only freely reusable media, but the obligations differ per file — some require attribution, some are public domain, some are share-alike. Atsumia stores the author, licence name and licence URL for each file and shows them on the card, rather than assuming one licence for everything.
Sensitive and disputed geography
Geographic datasets contain offensive historical names, disputed territories and sensitive sites. Atsumia does not adjudicate political questions: it stores what the source says, keeps the provenance, and provides a reversible way to hide a card without destroying the imported record or anyone’s ownership history. Country and territory classification deserves a written policy before any broad international release.
