MQTT Fundamentals for the Unified Namespace
The article discusses key aspects of MQTT in relation to a Unified Namespace (UNS), highlighting four essential mechanisms: broker-mediated pub/sub, quality-of-service levels, retained messages, and Last Will functionality. It explains how MQTT ensures effective communication, addressing misconceptions about delivery guarantees and exploring its historical context, strengths, and application in industrial settings.

Why Point-to-Point Integration Fails at Scale
Point-to-point integration becomes problematic as the number of systems increases, leading to a combinatorial explosion of interfaces and heightened fragility at ISA-95 level boundaries. This method incurs significant costs, including ongoing support and operational risks, making it unsuitable for larger plants. A unified namespace presents a scalable alternative for integration.

What Is a Unified Namespace? A Ground-Up Definition
A unified namespace (UNS) is an event-driven architecture in which every system in a plant publishes its current state to one central broker, organized in a semantic hierarchy that mirrors the business. Any producer writes to it. Any consumer reads from it. Nothing integrates point-to-point. The result is a single, live source of truth: at… Read →
