# Third-party notices — Typing keyboard
|
||
|
||
The generated Chinese source manifest is
|
||
`OSGKeyboard/Resources/Typing/Rime/manifest.json`. Exact librime
|
||
binary dependency licenses are bundled beside `NOTICE.txt`.
|
||
|
||
## Distributed components (Chinese IME)
|
||
|
||
| Component | Pinned version / commit | License | Purpose |
|
||
|-----------|-------------------------|---------|---------|
|
||
| [librime-xcframework](https://github.com/ghostflyby/librime-xcframework) | `1.17.0-pack.1`, package `d578192…` | BSD-3-Clause + bundled dependency notices | Static iOS librime runtime |
|
||
| [rime/librime](https://github.com/rime/librime) | `1.17.0` | BSD-3-Clause | Chinese input-method engine |
|
||
| [rime-pinyin-simp](https://github.com/rime/rime-pinyin-simp) | `0c6861e…` | Apache-2.0 | Permissive baseline dictionary |
|
||
| [fxsjy/jieba](https://github.com/fxsjy/jieba) | `67fa2e3…` | MIT | Modern Simplified-Chinese word frequencies |
|
||
| [phrase-pinyin-data](https://github.com/mozillazg/phrase-pinyin-data) | `cee0ed6…` | MIT | Phrase pronunciations |
|
||
| [pinyin-data](https://github.com/mozillazg/pinyin-data) | `923b108…` | MIT | Character-pronunciation fallback |
|
||
|
||
`Scripts/typing/build_rime_dictionary.py` deterministically merges these
|
||
sources into `osg_pinyin.dict.yaml`; its manifest records every source URL,
|
||
commit, SHA-256 and output SHA-256.
|
||
|
||
## OSG-owned pieces
|
||
|
||
- SwiftUI QWERTY / candidate UI, `RimeEngineBridging`, and the English
|
||
suggestion / autocorrect / next-word session layer.
|
||
- Objective-C++ C-API bridge for librime.
|
||
- Full-pinyin, Microsoft-double-pinyin and Sogou-double-pinyin schemas.
|
||
- Microsoft/Sogou mappings were independently encoded from public key-map
|
||
specifications; GPL schema files were not copied.
|
||
- Eight opt-in fuzzy-pinyin rule groups.
|
||
- Offline English typing data under
|
||
`OSGKeyboardShared/Resources/Typing/English/`:
|
||
- `english_lexicon.bin` — mmap-friendly binary of the top 40k alphabetic
|
||
unigrams (log-scaled ranks) plus truncated bigrams; this is what the
|
||
keyboard extension loads
|
||
- `english_lexicon.tsv` / `english_bigrams.tsv` — build inputs derived from
|
||
Peter Norvig’s public-domain `count_1w.txt` / `count_2w.txt`
|
||
(https://norvig.com/ngrams/; not GPL/LGPL dictionaries). Not copied into
|
||
the app bundle.
|
||
- Rebuild with `python3 Scripts/typing/build_english_lexicon.py`
|
||
(add `--from-tsv` to compile the binary from existing TSV without network)
|
||
|
||
|
||
## Reference only

||
|
||
NanoMouse commit `a6177d898a01662ce551b43a01cf82a9f84ca54c`
|
||
(MIT) was used to understand iOS Rime lifecycle boundaries. Its KeyboardKit,
|
||
UI, data packages and application features are not linked into OSGKeyboard.
