German Wiktionary - FULL Normalized SQLite Database

This is a complete, lossless, and fully normalized SQLite database of German Wiktionary, capturing 100% of the structured data from the cstr/de-wiktionary-extracted dataset.

It is designed for production-ready applications, complex linguistic analysis, and mobile apps (Flutter, React Native) that require a comprehensive local dictionary.

🎯 Key Features

✅ 100% Lossless: All 30+ top-level and nested fields from the source JSONL are preserved.
⚡ Fast Queries: Fully indexed schema for sub-20ms queries.
🔗 Full Semantic Web: Includes all semantic relations (synonyms, antonyms, hypernyms, hyponyms, meronyms, holonyms, coordinate_terms).
🗣️ Rich Content: Includes expressions, proverbs, and entry notes in addition to definitions and examples.
📱 Mobile-ready: Optimized for sqflite (Flutter) and other local DB use cases.
(and all features from the standard DB: forms, translations, sounds, etc.)
