Orchard is an Open Source CMS being developed by Microsoft that uses .NET MVC. Orchard is currently working toward a V1 release hopefully in Jan 2011. The project currently includes an extensibility model for both modules and themes, and dynamic content type system, ease of customization, and more.
Orchard just completed our second major milestone, focused on Web designers. Included in this release is a new theme engine (Razor syntax by default), a flexible shape/template/layout system, a widget framework, and more. “The Theme Machine” is the default theme that take advantage of all these features.
Orchard will create shared components for building ASP.NET applications and extensions, and specific applications that leverage these components to meet the needs of end-users, designers, developers, and Web professionals. Additionally, we seek to create partnerships with existing application authors to help them achieve their goals. Orchard is delivered as part of the ASP.NET Open Source Gallery under the Outercurve Foundation. It is licensed under a New BSD license, which is approved by the OSI.
The intended output of the Orchard project is three-fold:
•Individual .NET-based applications that appeal to end-users, designers, developers, and Web professionals
•A set of re-usable components that makes it easy to build such applications
•A vibrant community to help define these applications and extensions
In the near term, the Orchard project is focused on delivering a .NET-based CMS application that will allow users to rapidly create content-driven Websites, and an extensibility framework that will allow developers and customizers to provide additional functionality through module extensions and themes.
