How to read it
Parquet is a columnar format readable by every mainstream data tool — pandas, polars, DuckDB, R/arrow, Apache Spark. A quick start in Python:
import pyarrow.parquet as pq
sites = pq.read_table("sites.parquet").to_pandas()
print(sites[sites.status == "ok"].sort_values("mean_iptc_score", ascending=False).head()) Or with DuckDB directly against the raw URL (no download needed):
duckdb -c "SELECT site_id, mean_iptc_score FROM 'https://github.com/iptc/metawatch/raw/main/data/runs/2026-05-13/sites.parquet' WHERE status = 'ok' ORDER BY mean_iptc_score DESC LIMIT 10;" File layout
| File | What's in it |
|---|---|
runs.parquet | 1 row per run — start/end times, totals. |
sites.parquet | 1 row per site per run — discovery strategy, status, articles & images sampled, mean score. |
articles.parquet | 1 row per article fetched — URL, publication date, http status, JSON-LD payload. |
images.parquet | 1 row per image — URL, dimensions, CDN attribution, per-image score, presence flags. |
metadata_fields.parquet | 1 row per (image, field) tuple — long-form table for per-field aggregation. |
