This repository contains open‑source, machine‑readable JSON representations of major library classification systems:
- Dewey Decimal Classification (DDC)
- Universal Decimal Classification (UDC)
- Library of Congress Classification (LCC)
The goal is to provide a structured, reusable data source for developers, librarians, and researchers who work with library metadata, cataloging tools, or knowledge organization systems.
This repo contains English and Bahasa Indonesia in JSON Format.
Library classification numbers are the backbone of any physical or digital library. Having these schemas in a clean, parseable format allows:
- Building search interfaces that suggest related subjects
- Validating call numbers in library software
- Creating educational tools (like the interactive demo on curatorian.id)
- Automating collection analysis and mapping
All data is offered under an open license to encourage reuse and collaboration.
