openDoors

openDoors is an open-source framework and standard for door access control and automation. It provides software components, data models, and guidelines that enable organizations to manage entry systems, authenticate users, monitor door status, and integrate with a range of hardware such as electronic locks, readers, and sensors.

Origin and governance: The project began as a collaborative effort among developers, facilities managers, and researchers from multiple countries, with the goal of enabling interoperable door control solutions. It is released under an open-source license and is governed by a community-driven model that includes a steering committee, contribution guidelines, and public discussions.

Architecture and features: openDoors uses a modular architecture consisting of a core server, plug-ins for different door controllers, and client libraries. It exposes RESTful APIs and supports identity federation through standards such as OAuth 2.0 and JSON Web Tokens. Core capabilities include access policy management, multi-factor authentication support, real-time door status, audit trails, event-driven alerts, and extensibility via plug-ins for various hardware.

Security and privacy: The framework emphasizes secure communications (TLS), encrypted event logs, and role-based access control. It advocates data minimization and regular security audits, while noting that improper configuration or unpatched components can create vulnerabilities.

Impact and usage: Open-source adoption has been reported in educational institutions, libraries, coworking spaces, and small enterprises that seek interoperable door systems. Critics note that while open standards promote interoperability, successful deployment requires expertise in identity management and hardware integration, and ongoing maintenance.
