Welcome to the Unified Modeling Language™ (UML®) website. Feel free to browse news and articles on UML, success stories, available certification and training, along with the current specifications. UML is OMG's most-used specification, and the way the world models not only application structure, behavior, and architecture, but also business process and data structure. Our members define and maintain the UML specification which we publish in the series of documents for your free download. Software providers of every kind build tools that conform to these specifications. To model in UML, you'll have to obtain a compliant modeling tool from one of these providers and learn how to use it. If you're new to modeling and UML, start with our own Introduction to UML.
