Electoral Rolls — West Bengal, 2002

Overview

This repository implements end-to-end workflows for collecting West Bengal electoral roll PDFs across two eras, then packaging large-scale outputs for reliable release and reuse.

Data and Sources

• Booth-level 2002 roll links from ceowestbengal.nic.in captured into manifest tables.
• ASD/MOM 2025 flows from wb.gov.in public endpoints with district-level filtering.
• Raw, interim, processed, and metadata layers tracked as separate pipeline stages.

Workflow

• Automate URL collection and PDF download with retry logic and status-aware manifests.
• Provide targeted failure-retry scripts rather than restarting full download cycles.
• Build release assets as chunked zip parts with checksums and scripted publish plans.

Outputs

• Large archival electoral-roll collections structured for reproducible distribution.
• Operational scripts for reruns, recovery, and release automation.
• Portable release artifacts for independent research and verification.
