Data Quality & Assurance

Data Quality & Assurance

Dealcharts is the open context graph for structured finance. Quality = verifiable provenance + live assurance. Every object carries lineage, coverage, freshness, and latency so you can judge reliability at a glance.

Assurance Glossary

• Coverage — % of required fields populated for this object/period

• Freshness — age since last successful source ingest

• Latency — time from source publish → platform update

• Last schema change — latest structural change affecting comparability

What we publish

• Context, not conjecture. Pages link entities (issuers, servicers, funds) to deals, shelves, tranches, and filings.

• Citations by default. Each chart or profile points back to public sources (e.g., EDGAR).

• Provenance everywhere. Edits and submissions include author + timestamp.

Live quality indicators

Below you'll find current signal on gaps, conflicts, and coverage. These update as we ingest and review filings.

How we fix errors

1. Users click "Spot an error?" and submit a correction or confirmation.

2. We check against primary sources and related entities.

3. Approved changes are published; provenance is retained.

Verification improves the graph

• Verified Entities confirm identifiers, official links, and a short "About."

• Verified details cascade to related charts and pages, reducing drift across the site.

• Learn more → Contact us for entity information.

Update cadence

• Ingestion from public sources occurs on a recurring schedule (often weekly).

• Entity disambiguation and relationship mapping are refined continuously.

Known gaps (rolling)

• Inconsistent issuer/servicer naming across filings

• Historical tranche renames

• Shelf alias normalization for legacy deals

What to do if you find an issue

• Use "Spot an error?" on the affected page, or email quality@dealcharts.org with links/screenshots.

• Verified entities receive priority review.
