The 53 bundled metro networks are prepared from OpenStreetMap data. OpenStreetMap attribution applies to those network graphs and track geometries.

02 / HONG KONG
MTR Corporation Limited and DATA.GOV.HK.
Hong Kong static station information and live-arrival references are attributed to MTR Corporation Limited and DATA.GOV.HK. Reuse of the government dataset remains governed by DATA.GOV.HK Terms and Conditions of Use version 1.2.
| Resource | Official link | Role |
|---|---|---|
| MTR data provider | Provider page ↗ | Names the provider for Hong Kong transit data. |
| Next Train API | Dataset record ↗ | Source record for live MTR arrival information. |
| Terms of Use | DATA.GOV.HK terms ↗ | Governs reuse and attribution. |
03 / TAIPEI
Taipei Metro Open Data.
The Taipei city pack uses vendored station and entrance snapshots published through data.taipei by Taipei Rapid Transit Corporation. Reuse is governed by the Open Government Data License, Taiwan, version 1.0, including its attribution requirements.
04 / MAINLAND OPERATORS
Identifiers and recipes, not copied content.
Beijing, Shanghai, Guangzhou, and Hangzhou station references include reviewed operator identifiers, canonical station mappings, aliases, source URLs, and Just-Go-authored request/mapping recipes. Operator station text, schedules, facilities, exits, descriptions, images, and layouts are not republished as a Just-Go service.
| Operator | Official site | Current use |
|---|---|---|
| Beijing Subway | bjsubway.com ↗ | On-device station-information fetch; eligible last-good snapshot remains device-only. |
| Shanghai Metro | shmetro.com ↗ | On-device station-information fetch. |
| Guangzhou Metro | gzmtr.com ↗ | On-device line and service-time fetch. |
| Hangzhou Metro | hzmetro.com ↗ | On-device line and service-time fetch. |
05 / EXTERNAL RESOURCES
770 links remain external.
The reviewed catalog contains 770 link records resolving to 698 unique targets across 43 cities. Linked pages, PDFs, images, maps, and other resources remain with their providers. A user-initiated link does not copy the destination into Just-Go or change its license.
06 / UNIVERSAL CITY FORMAT
One document, the full source union.
Each of the 58 developer-facing universal city documents combines authored schema fields with the city’s applicable network, station, official-resource, coverage, and rights records. The files are integrity-indexed repository artifacts and are not bundled into the app.
Publishing one JSON shape does not place every field under one license. Each city document carries rights identifiers, and downstream consumers must preserve the terms attached to its sources.
07 / SOFTWARE
Just-Go source code.
Just-Go’s original software source is published under the MIT License. The MIT grant does not replace third-party database, data, service, name, trademark, or website terms.
