Microsoft Boosts Modeling Strategy and Rejoins OMG
9/15/2008
Microsoft, as part of its overall initiative to support modeling capabilities, especially in its .NET Framework, last week joined the Object Management Group (OMG), a nonprofit organization that fosters integration standards for the enterprise.
The announcement signals a greater openness for Microsoft. Joining the OMG is somewhat like Microsoft's embrace of open Web server standards collaboration when it joined the Apache Software Foundation in July, according to Jeffrey Hammond, senior analyst at Forrester Research.
The OMG is known for a number of modeling approaches under its Meta-Object Framework and Model Driven Architecture (MDA), but its Unified Modeling Language (UML) is perhaps the best known component. UML is "deliberately domain-independent and platform-agnostic," according to an OMG white paper. It creates profiles that other platforms or applications can support.
Microsoft's announcement could indicate that the company is embracing UML, although the company didn't specifically admit to it. Instead, Microsoft has long championed a lightweight modeling approach, called Domain Specific Languages (DSL), as an alternative to UML.
Hammond said it wouldn't surprise him to see UML pop up in the Microsoft world, but that Microsoft probably views UML "as a great DSL for software architects." He added that the Microsoft Visio application "includes UML templates that are quite good." One of the issues for Microsoft early on was the problem of complexity in modeling, and "Microsoft rightly noted that building off UML 2.0 can create some complex tooling for architects and developers," Hammond said.
Still, a Forrester study conducted for Unisys found that three quarters of organizations doing modeling and model-driven development were using the OMG's UML.
UML was originally championed at OMG by Rational, and Microsoft backed it early on with Rational Rose. Later, IBM acquired Rational.
"There were significant differences over modeling, specifically the Model Driven Architecture that the OMG had been promoting," Hammond explained. "Rational was one of the key proponents of UML and they [Microsoft] were very much involved with Rational in the early days. They actually shipped a limited edition of Rose in Visual Studio back in the 1998 time frame, and were very much pro-UML, but that changed and they moved away from it for a variety of reasons."
Microsoft currently has two of its own model-driven development technologies -- Extensible Application Markup Language (XAML) and ASP.NET model-view-controller -- which developers can use now. Those technologies will be part of "Oslo," a broad Microsoft modeling integration effort under development, as well as Visual Studio "Rosario," according to Microsoft's announcement. Rosario is the planned Team System version that will follow Visual Studio Team System 2008.
