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.

# Download compressed database
db_gz_path = hf_hub_download(
    repo_id="cstr/de-wiktionary-sqlite-full",
    filename="de_wiktionary_normalized_full.db",
    repo_type="dataset"
)

# Decompress (if it's .gz)
db_path = db_gz_path.replace('.gz', '')
with gzip.open(db_gz_path, 'rb') as f_in:
    with open(db_path, 'wb') as f_out:
        shutil.copyfileobj(f_in, f_out)

# Connect
conn = sqlite3.connect(db_path)
```

### Example Query (New Tables)
```python
# Get all hypernyms (parent categories) for "Hund"
