Sources & License

Copybooks in Dutie use National Palace Museum open data or images from Wikimedia Commons. This page explains the source, the license, and what we changed.

Source

National Palace Museum Open Data (Taipei): digitalarchive.npm.gov.tw/opendata. Dutie uses the 6-megapixel image files and the text from it.

License

The 6-megapixel image files and the text are licensed under CC BY 4.0 (Creative Commons Attribution 4.0 International): free to use, including commercially, on condition that the source is credited. The full license is on the Creative Commons page.

How it is credited

Museum copybooks use the credit format provided by the Museum:

品名。國立故宮博物院，台北，CC BY 4.0 @ www.npm.gov.tw

where “品名” is the title of that copybook.

Wikimedia Commons

For Commons images, the app shows “來源：Wikimedia Commons”, the author and the license name, with links to the source file and license terms when available. The collection and object number appear only when provided. Licenses include Public Domain, CC0, CC BY and CC BY-SA, with the version shown on each copybook. A cropped CC BY-SA image must be shared under the same license.

What Dutie changed

CC BY 4.0 requires saying whether the original was modified. Dutie crops the images and adds camera movement (the effect of a camera moving across the picture and resting on each passage). What you see in the app is therefore a processed version, not the original image supplied by the Museum. To see the original, go to the Museum’s open data.

Relationship with the Museum

Dutie is an independent app. It is not affiliated with or partnered with the National Palace Museum, and the Museum does not endorse this app.
