Welcome

The UML Forum is a web community dedicated to the Unified Modeling Language (UML), the industry-standard visual modeling language for specifying software-intensive systems. Here you can find information related to UML specifications, UML tools, UML training, UML processes, UML publications, and UML mailing lists.

The Unified Modeling Language (UML) is a graphical language for visualizing, specifying, constructing and documenting the artifacts of software-intensive systems. The UML was originally derived from the object modeling languages of three leading object-oriented methods: Booch, Object Modeling Technique (OMT) and Object-Oriented Software Engineering (OOSE). It was first added to the list of Object Management Group (OMG) adopted technologies in 1997, and has since become the industry standard for modeling software-intensive systems.

October 31, 2008 - Dial 'M' for Marketecture: Microsoft Elaborates Upon Oslo 'M' Modeling Language at PDC 2008.
Microsoft elaborated upon its Oslo modeling strategy during its annual Professional Developers Conference (PDC) held in Los Angeles this week. It appears that the core technologies associated with the Oslo modeling strategy include a text-based Domain Specific Language (DSL) code-named 'M', a design "surface" named Quadrant, and a repository for semantic models that it is currently unnamed. (Why not 'R'?) Given Microsoft's announcement last month that is joining the OMG, it is less than clear how text-based 'M' will help the OMG with its motley mix of semantically inconsistent and non-interoperable visual modeling languages, which include UML, OMG SysML, and BPMN. Will 'M" make the OMG's alphabet soup of modeling languages taste better or worse? For a NY Times article about Oslo modeling languages click here.

October 15, 2008 – OMG Board of Directors Votes to Adopt UML 2.2 and OMG SysML 1.1 Revisions.
The Object Management Group (OMG) Board of Directors met in Orlando, Florida during the week of 22-26 September 2008 to approve nine new and and revised specifications. Among the revised specifications they voted to adopt were UML 2.2 and OMG SysML 1.1. You can download convenience documents for the UML 2.2 and OMG SysML 1.1 revisions using links found on the Specification pages of the UML Forum and SysML Forum, respectively.

September 10, 2008 - UML Beats DSLs to Model-Driven Development Punch?: Microsoft Joins OMG.
Microsoft today outlined its approach for incorporating modeling into mainstream computing and announced that it is joining the Object Management Group (OMG),  the standards body responsible for defining the UML and BPMN modeling languages. "We're building modeling in as a core part of the platform," said Bob Muglia, senior vice president, Server and Tools Business at Microsoft. Does this mean that Microsoft is abandoning its Domain Specific Language (DSL) modeling strategy in favor of a General Purpose Language (GPL) modeling standard, or is this just Muddle Driven Marketecture hype?
