UML (Unified Modeling Language) is the standard modeling language for software architecture, system design, and technical documentation. Governed by the Object Management Group (OMG), UML defines a set of notation conventions and diagram types — class, sequence, activity, use case, state, component, deployment, and more — used across the software development lifecycle. This collection profiles the ecosystem of tools, APIs, and services that work with UML diagrams programmatically.
