Licences and open source

Daolang is built on other people’s work: dictionaries, recordings, fonts and software. Here are their authors and licences.

Course data

CC-CEDICT

CC BY-SA 4.0

MDBG and the CC-CEDICT contributors

English meanings of words, and the readings behind the «Type the characters» keyboard. Meanings are shortened and selected for the course. The app's English glosses are derived from CC-CEDICT and are shared under the same licence.

Pronunciation recordings

CC BY-SA

Words recorded by native speakers, from an open corpus. The recordings are unchanged: loudness is evened out on playback.

大BKRS

Free use under the bkrs.info terms

BKRS contributors, bkrs.info

Russian meanings of words, selected and shortened for the course.

hanzi-data

MIT

argb

Russian meanings of HSK 1–6 words — one of the opinions the glosses were chosen from.

Make Me a Hanzi — graphics.txt

Arphic Public License

Shaunak Kishore; outlines from the Arphic PL KaitiM GB and Arphic PL UKai fonts (Arphic Technology)

Character outlines and stroke order, for writing and for taking characters apart. Only the characters the course needs are taken.

Make Me a Hanzi — dictionary.txt

GNU LGPL 3.0 and the Unicode notice

Shaunak Kishore; based on Unihan (Unicode, Inc.) and cjklib

How characters break into parts — for «Build the character from its parts» and the character notes. The data is modified: selected and extended for the course; it ships with the app as components.json.

Hanzi Writer data

Strokes of characters the app does not carry — fetched from the network (jsDelivr) when they are opened.
