Microsoft Assistance Markup Language

A markup language related to: Windows Vista™ - AP (Assistance Platform) Help
Windows Vista introduces a breakthrough user experience and is designed to help you feel confident in your ability to view, find, and organize information and to control your computing experience.

Microsoft Assistance Markup Language (MAML) is a XML based markup language used by "Longhorn" Help. The current help system HTMLHelp 1.x is using HTML topic files. HTML is a markup language that combines presentational and semantic elements.The most significant aspect of MAML is the shift to a structured authoring model. Documents and their constituent elements are defined semantically, placing the focus on content rather than formatting. Presentation is controlled at rendering time, adding a new degree of flexibility.

MAML consists of several distinct content types, each one specific to a type of document. The MAML content types include: conceptual, FAQ, glossary, procedural, reference, reusable content, task, troubleshooting, and tutorial.

Content authored in MAML can be output to many different formats, including DHTML, XAML, RTF, and print. When MAML content is presented online, there are three levels of run-time transformation: structural, presentational, and rendering. Structural transformation uses reusable content and applies conditional logic, determining the content that will appear, and the structure of that content. The resulting MAML format document is then ready to move onto the presentational transformation stage. At this point, the content is transformed into one of the presentation formats (DHTML, XAML, or RTF). Rendering transformation is the final stage where stylesheets are applied and the content is displayed in its final form.

Microsoft Windows Vista is a line of graphical operating systems used on personal computers, including home and business desktops, notebook computers, Tablet PCs, and media centers.

On January 30, 2007, it was released worldwide to the general public and was made available for purchase and downloading from Microsoft's web site. The release of Windows Vista comes more than five years after the introduction of its predecessor, Windows XP, making it the longest time span between two releases of Microsoft Windows.

Windows Vista contains hundreds of new features; some of the most significant include an updated graphical user interface and visual style dubbed Windows Aero, improved searching features, new multimedia creation tools such as Windows DVD Maker, and completely redesigned networking, audio, print, and display sub-systems. Vista also aims to increase the level of communication between machines on a home network using peer-to-peer technology, making it easier to share files and digital media between computers and devices. For developers, Vista includes version 3.0 of the .NET Framework, which aims to make it significantly easier for developers to write high-quality applications than with the traditional Windows API.

There are several editions of Windows Vista:
- Windows Vista Starter
- Windows Vista HomeBasic
- Windows Vista Home Premium
- Window Vista Business
- Windows Vista Enterprise
- Windows Vista Ultimate
