# UGR'16 — canonical flow parquet

The complete [UGR'16 dataset](https://nesg.ugr.es/nesg-ugr16/) (University of
Granada / Spanish ISP NetFlow, March–August 2016) converted from the published
weekly nfdump CSV tarballs into a canonical flow-record parquet schema.

- **23 weekly files** (17 calibration March–June, 6 test July–August;
  `april_week1` does not exist upstream), ~16.6 billion flows, 210 GB zstd
  parquet. One parquet per week — calibration/test splits rebuild from
  filenames.
- **Labels**: `background` and `blacklist` map to `label_binary="unknown"`,
  never "benign" — background ISP traffic was screened, not verified.
  Attack rows keep their family verbatim (`dos`, `scan11`, `scan44`,
  `nerisbotnet`, `anomaly-spam`, ...) in `label_attack`.
- **NetFlow honesty**: records are unidirectional; reverse counters are null
  (not zero), and there are no packet sequences (Tier A features only).
- 50,098 mangled source lines (0.0003% of the corpus, concentrated in
  `april_week3`) were skipped and logged during conversion.
- `ugr16-manifest.json` records per-file conversion provenance.
