# ECLI → BWB legislation references
Links Dutch case law (**ECLI**) to the Dutch legislation it cites (**BWB**
identifiers from the Basiswettenbestand register), resolved via LIDO
(Linked Data Overheid).
One row per (case, cited law element): a single ECLI has one row for every
statutory element it references.

## Usage
```python
import pandas as pd
df = pd.read_parquet("hf://datasets/davidwickerhf/ecli-bwb-id/ecli-bwb-id.parquet")
# All laws cited by one decision
df[df.ecli == "ECLI:NL:HR:2019:1734"]
# Most-cited articles
(df[df.type == "artikel"]
.groupby(["bwb_id", "number", "title"]).size()
.sort_values(ascending=False).head(20))
```
Deep links per row:
- `http://wetten.overheid.nl/{bwb_id}` — the law text
- The `jc_id` JuriConnect string pins the exact element and version date.
