Zotonic is a modern, high-performance Content Management System (CMS) and web framework specifically designed to handle semantic data and provide high-connectivity for web applications. It is built using Erlang, which allows it to maximize processing power and speed.

The main features of this tool include:

• Semantic Data Model: Zotonic uses a pragmatic implementation of the Semantic Web, combining traditional database concepts with a model that excels at managing structured data from multiple sources. This makes complex data relationships manageable for human users.

• Real-Time Connectivity: The platform features deep integration with the MQTT protocol (commonly used in the Internet of Things) for publish/subscribe messaging. This allows for real-time browser/server interaction and live-updating content, such as search pages that refresh as you type.

• Comprehensive Developer Framework: Beyond being a CMS, it is a full framework that includes controllers, templates, dispatch rules, and filters. It provides extensive tools for developers, including a command-line shell, Docker support, and a template tracing tool to visualize how pages are rendered.

• Advanced Collaboration and Access Control: It includes a sophisticated access control system and supports collaboration groups, which allow teams to organize and manage members and private content without complex setup.

• High Performance and Scalability: By leveraging Erlang, Zotonic is built to be "blazing fast," focusing on maximizing system power for modern web demands.

• Modular and Extensible Architecture: The system is highly modular, allowing developers to create custom modules, actions, and validators. It also includes built-in handlers for email, media, and automated testing.

• Open Source and Secure: Distributed under the Apache 2.0 license, Zotonic prioritizes security with built-in features to prevent Cross-Site Scripting (XSS) and other injection attacks.
