Twinkle Hub passes each source's original license metadata to your client unchanged — we don't silently relicense or strip terms. This page lists every license that appears across Twinkle Hub's coverage.
Each MCP tool response carries a license field in its metadata (e.g. OGDL-Taiwan-1.0). Your agent / app sees it as-is and can decide whether to cite, attribute, or filter. We don't strip the field.
Licenses across the 52,960 datasets currently indexed (source: data.gov.tw)
OGDL-Taiwan-1.0
52,919 datasets · 99.92%
The standard license for Taiwan government open data, issued by NDC. Commercial use, redistribution, and adaptation all allowed. Source attribution is requested. No real friction for AI integrations.
CC-BY-4.0
16 datasets · 0.03%
Standard international CC license. Commercial use, redistribution, and adaptation allowed; you must retain the original author / source / license link.
CC0-1.0
15 datasets · 0.03%
Provider waives all rights — effectively public domain. Commercial use, redistribution, adaptation are unrestricted; attribution isn't strictly required (still recommended).
CC-BY-SA-4.0
8 datasets · 0.02%
Commercial use, redistribution, adaptation allowed, but derivatives must be released under the same CC BY-SA license. Take care when ingesting into a publicly-released LLM dataset.
OFL-1.1
2 datasets · 0.00%
Font-specific license. Commercial use and modification allowed, but a modified font cannot be sold by itself — it must accompany an app / document. Rarely applies to datasets.
Multi-country data tools (Hong Kong / Japan / Korea / United States / Singapore) are governed by each source government's open-data licence. As with Taiwan data, the license field is passed through verbatim on every tool response — never removed or rewritten.

Which license each source publishes under. Onboarded sources list their primary license; exploring sources will publish terms when we integrate them.
