This is one the questions that I have had for awhile. Thanks the to Lynn Langit developer evangelist extraordinare. The Oslo model is starting to take shape.

”Oslo” is the codename for Microsoft’s forthcoming modeling platform. Modeling is used across a wide range of domains and allows more people to participate in application design and allows developers to write applications at a much higher level of abstraction. “Oslo” consists of:

• A tool that helps people define and interact with models in a rich and visual manner
• A language that helps people create and use textual domain-specific languages and data models
• A relational repository that makes models available to both tools and platform components

“Oslo” was first announced by Robert Wahbe (Corporate Vice President of the Connected Systems Division) in October 2007.

And from Bill Gates at Tech Ed

“I think one of the biggest trends in application development that I talked about… is modeling, and we're making a big investment in that. We have what's been code named Oslo, and talked a little bit about it on our Web sites and our blogs, which is this model-driven development platform. It's actually taking the kind of models that you're seeing arising in specific domains, like software management in System Center, or your data design over in SQL, or your process activities over in BizTalk and saying, we need to take all these domains and be able to put them into one model space. In fact, we need to let people create their own domains that aren't just isolated, but that exist in this one modeling space. And that's what Oslo is about.”

Take a closer look at it from a website that Microsoft Has Set up for SOA and OSLO Here. I look forward to seeing what this is all about since I have been playing alot with the entity framework. Models make the code not only more readable there fore easier to understand. What will they announce on this at PDC bring us?
