Chinese dictionary data

CC-CEDICT, release 2026-08-10T07:59:10Z — CC BY-SA 4.0. Community maintained Chinese-English dictionary published by MDBG. Original filename cedict_ts.u8. Downloaded source form: cc-cedict-2026-08-10.txt.gz. Official release page: MDBG CC-CEDICT. License.

Unicode Unihan Database 17.0.0 — Unicode License v3. Copyright © 1991-2026 Unicode, Inc. The pinned Unihan readings source supplies kHanyuPinlu frequency counts and kMandarin preferred readings for deterministic single-character lookup priority. See the complete copyright and permission notice and official archive.

The shipped lookup TSV and lookup-only Jieba additions are adapted CC BY-SA material. Transformations (normalizing definition separators, adding an explicit zero HSK column, ranking single-character readings from pinned Unihan data, assigning deterministic fallback frequencies, omitting built-in Jieba words, and excluding four split-rule words) and SHA-256 values are in the provenance manifest. No extension-specific GPL code or data is copied.

Experimental Spanish language pack

The Spanish pack is authorized for an experimental public preview. “Experimental” describes its current quality and support level, not a distribution-license restriction. Exact lengths and SHA-512 hashes for every artifact and bundled notice are recorded in the Spanish pack manifest.

Apache OpenNLP Spanish UD GSD models 1.3 — Apache-2.0. The tokenizer, part-of-speech, and lemmatizer models were converted into LangSail's browser format. See the upstream models, bundled license, and bundled notice.

Doozan/Wiktionary Spanish-English data — CC BY-SA 4.0. The upstream data was converted into a ranked line-oriented lookup TSV and combined with reviewed application-owned supplements while retaining source-order senses. See the upstream attribution and bundled license.

FrequencyWords-derived Spanish data — CC BY-SA 3.0. Frequency-derived material distributed through doozan/spanish_data contributes to the generated morphology table. See the upstream project, upstream attribution, and bundled license.

Discovery works

Discovery currently ships exactly five Global Storybooks Chinese works. The catalog records each author, Chinese translator, source URL, pinned source revision, exact license, and text-only sentence-block modification:

global-storybooks-zh-0087 我喜欢看书 — Letta Machoga; illustrations Wiehan de Jager; translated by dohliam; narration Zhuo Sun — CC BY 3.0.
global-storybooks-zh-0027 决定 — Ursula Nafula; illustrations Vusi Malindi; translated by Vicky Liu; narration Zhuo Sun — CC BY 4.0.
global-storybooks-zh-0296 卖香蕉的汤姆 — Humphreys Odunga; illustrations Zablon Alex Nguku; translated by Vicky Liu; narration Zhuo Sun — CC BY 4.0.
global-storybooks-zh-0006 阿南西和智慧 — Ghanaian folktale; illustrations Wiehan de Jager; translated by dohliam; narration Zhuo Sun — CC BY 3.0.

All five use source revision dc10707c3dfa58512b277d4c89492ecf2ce86390. Content hashes (SHA-256) are: 0087 1c22e098b5df7fe9d00a25276a743efacc374b32e5bb8313660f5c4a3bfd2ed9; 0027 1d3fa14dc982214ee80bbbcf80d68a2bbd5a97639a7d52b4cc13eaab12c2e7d4; 0296 b92bfba3a5b28839888d1ecdcd871f52e682780ce54a2c1c4ed0725c546a95eb; 0006 2db3cbc0dfc8bd0a17709a1a2c65121039dc9f49bd4a95f74d82ba38f0e4df24; 0110 466255e58aa172d8abd50ba5219dda6d4aacbfa0232facabd748ba178d9869d7. See the machine-readable inventory and the source collection; each Discovery card also exposes its editorial form, adaptation statement, and content notes.

Artwork and exclusions

The favicon, install icons, sail marks, social card, and their SVG/PNG variants are original LangSail artwork generated by scripts/render-brand-assets.mjs. The public sync-opportunity.js helper is original LangSail code. No third-party fonts, images, audio files, speech models, translation models, or embedding models are bundled. The experimental Spanish analysis models and data are covered above and in the Spanish pack manifest. Browser/system fonts are used.
