DartLab Data

Structured company data from DART & EDGAR disclosure filings

DART 전자공시 + EDGAR 공시 데이터 — 한국 2,700사 / 미국 970사

What is this?

Pre-collected Parquet files from DartLab — a Python library that turns DART (Korea) and EDGAR (US) disclosure filings into one structured company map.

한국 DART 전자공시 시스템과 미국 SEC EDGAR에서 수집한 기업 공시 데이터입니다.

This dataset is the data layer behind DartLab. When you run dartlab.Company("005930"), the library automatically downloads the relevant parquet from this repo.

Data Source

• EDGAR (US): sec.gov/edgar — SEC's Electronic Data Gathering, Analysis, and Retrieval system

All data is sourced from public government disclosure systems. Financial figures are preserved as-is from the original filings — no rounding, no estimation, no interpolation.
