Perpetual Motion Interactive Systems, a Microsoft technology solutions provider, has announced the availability of DotNetNuke 3.0, an open source content management system for the Microsoft ASP.NET platform. This major release offers forward compatibility with the much anticipated Microsoft ASP.NET 2.0 (Whidbey) platform, and adds new Localization and Search capabilities."Our community has taken a giant step forward with this release," said Shaun Walker, DotNetNuke creator and maintainer. "While the usability improvements in DotNetNuke 3.0 have simplified content management tasks for end-users on an international scale, the new portal framework has empowered developers and designers to create richer, more powerful application resources for the growing community. I am very proud of the development team who has worked so hard on this release over the past eleven months." DotNetNuke 3.0 includes a number of enhancements which improve its versatility, power, and accessibility. These include a more intuitive user interface, support for "drag-and-drop" content management, improved URL structuring for search engine indexing, and enhanced provisioning support for scriptable configuration. In addition, the application underwent an extensive code access security review so that it is capable of running in a Medium Trust hosting environment. Following are some of the 3.0 enhancements: Membership, Roles, and Profile -- Integration of the Microsoft ASP.NET 2.0 (Whidbey) Membership, Roles, and Profile API allows DotNetNuke to conform to a common Membership model. Localization -- Administration user interfaces for DotNetNuke can now be localized into any language. The architecture is based on the Microsoft ASP.NET 2.0 (Whidbey) localization system. Field & Module Help -- Localized field level help and module level help are now available on all administration user interfaces. Simplified & Organized Administrator UI – Administrator user interfaces have been reorganized to group common fields into collapsible sections to simplify the end-user experience, while still providing access to advanced functionality. A new control panel has been added which encapsulates more of the common administrative functions. Hoster Support – Improvements for Web Hosters include XML templates for scripting all aspects of the installation experience, feedback during the installation process, the ability to run in a Medium Trust environment, and optimized performance and memory consumption to maximize web server density. DotNetNuke will be sponsoring a number of third party sub-projects, providing an essential library of freely available, open source resources to augment the base portal framework. DotNetNuke 3.0 is available for free download. The full application source code and sub-projects are distributed under a standard BSD open source license.
