US Regulation eCFR 2026-01-01 Dataset

This repository contains a structured, machine-readable version of the Electronic Code of Federal Regulations (eCFR), captured as of January 1, 2026. Unlike the annual CFR snapshots, this dataset reflects the editorialized, near real-time version of federal regulations.

Dataset Description

The eCFR is a daily updated editorial compilation of CFR material and Federal Register amendments. This dataset captures a specific point-in-time snapshot of that fluid regulatory environment, structured for high-performance AI applications, semantic search, and legal analytics.

• —Source: GovInfo Bulk Data (eCFR)
• —Snapshot Date: 2026-01-01
• —Format: [Specify format, e.g., JSONL, Parquet, or CSV]
• —Focus: Current administrative law across all 50 Titles.

Data Acquisition & Integrity

This dataset was compiled using legitimate developer-sanctioned methods. Data was retrieved via official U.S. Government Publishing Office (GPO) bulk data endpoints and the eCFR API.

By utilizing official developer channels rather than traditional bot-based web scraping, the dataset ensures:

1. 1.Structural Consistency: Preserves the complex hierarchy of Titles, Subtitles, Chapters, Parts, and Sections.
2. 2.Metadata Enrichment: Includes versioning information and effective dates as provided by the GPO.
3. 3.Clean Ingestion: Optimized for RAG (Retrieval-Augmented Generation) by removing noise and maintaining the integrity of legal citations.

Potential Use Cases

• —RAG & Agentic Workflows: Providing LLMs with the most "current" version of federal regulations for accurate grounding.
• —Regulatory Intelligence: Analyzing the evolution of specific agency rules over time.
• —Compliance Automation: Mapping internal corporate policies to the latest eCFR requirements.
• —Cross-Title Linking: Discovering semantic relationships between different regulatory domains.

Structure

The dataset follows the official eCFR hierarchy:

• —Title: Broad subject area (e.g., Title 21 for Food and Drugs).
• —Chapter: Specific regulatory agency.
• —Part/Section: The granular text of the law.
• —Last Modified: Timestamp indicating the last editorial update to that section.
