Open & Communicating Architecture

Koha is a modern, browser-based library platform built from connected layers. Each layer has a clear responsibility, communicates through standards, and can evolve without locking the library into one vendor or device.

Koha architecture: open standards and clearly separated layers connect library users, systems, data and infrastructure.

External data sources

Z39.50, SRU and OAI-PMH connect Koha to external catalogues, repositories and metadata services.

Integration services

LDAP, SSO, REST APIs, SIP2, NCIP and third-party applications extend Koha into the wider library ecosystem.

Why this matters

Open interfaces make it easier to integrate, troubleshoot, secure and grow a library environment without rebuilding the whole system.
