Swingset

Swingset is an evidence-preserving dataset of competitive West Coast Swing results.

Load it

SELECT e.name AS event, p.place, leader.name_raw AS leader,

DuckDB can run this query directly. Polars, pandas, and Hugging Face datasets can read each table from the paths above. placements is the default config in this version. Hugging Face cannot stream an empty Parquet config, so calendar-only releases default to events; after results arrive, the default changes to placements.

Published coverage

This table is computed from the event rows in this exact dataset version. A source on an event identifies its evidence source or an explicitly labeled URL-override placeholder; it does not establish complete contest or round coverage.

Known gaps

• 128 contests have unsupported scoring layouts. Their raw evidence is retained privately; see review_queue for details.
• 487 of 573 events currently have event metadata but no parsed contest results.
• heats has 0 rows; public heat assignments are rarely available.
• Unverified callback codes and numeric marks remain in private evidence; they do not become negative callbacks or zero marks. WDR finals bibs stay null where partner ownership is unknown. Couple names remain a single couple entry when the source does not establish individual roles.
• Rows with snapshot_id = override are URL-override placeholders, not fetched source evidence. Their dates span the month encoded in the override ID; they are not verified event dates. Do not infer result coverage from these rows.

Sources and attribution

• WSDC event calendar (wsdc_calendar)
• WSDC points registry (wsdc_registry)
• EEPro (eepro)
• scoring.dance (scoringdance)
• danceconvention.net (dcn)
• World Dance Registry (wdr)

These sites remain the sources of their facts. Row-level source and snapshot_id fields identify the captured evidence where the table supports them. Coverage varies by source, event, round, and date; this card makes no claim of complete source or registry coverage.

Updates and corrections

Collection runs every 15 minutes when work is due. identity_links carries current identity confidence; changelog explains published changes. File corrections or removal requests at https://github.com/skeswa/swingset/issues.

Collection and personal data

Public calendars, registries, and score sheets are fetched serially per host, respecting robots, Retry-After, and a five-second request floor. An explicitly seeded registry sweep uses its documented two-second exception. Results include public competitor and judge names. Suppressed people keep structural rows with identity fields removed. Raw bodies stay private. Source terms continue to apply.
