Overview

Data Provenance

Trace Corpus records to EDGAR, exchanges, issuers, publishers, and courts.

Corpus preserves the source identifiers and timestamps needed to audit a research result.

  • Filing responses retain CIK, accession number, filing date, acceptance time, report date, form type, and SEC URL.
  • Normalized statements map source XBRL concepts to a versioned Corpus taxonomy.
  • Unmapped and amended facts remain available in the raw fact ledger.

India

  • Security records retain ISIN, NSE symbol, and BSE code where available.
  • Annual reports retain issuer identifiers, source URL, reporting period, artifact identity, and extraction status.
  • News and judgments retain their publisher or court source and document identity.
