Extensible Application Markup Language (XAML, pronounced zammel ([zæ:mɛl])) by Microsoft is a declarative XML-based language used to initialize structured values and objects.

Technology

XAML is used extensively in the .NET Framework 3.0 technologies, particularly in Windows Presentation Foundation (WPF), where it is used as a user interface markup language to define UI elements, data binding, eventing, and other features, and in Windows Workflow Foundation (WF), in which workflows themselves can be defined using XAML. The serialization format for workflows was previously called XOML, to differentiate it from UI markup use of XAML, but now they are no longer distinguished. However, the file extension for files containing the workflow markup is still "XOML".^[2] .NET Framework 3. ... This subsystem is a part of . ...

A workflow is a reliably repeatable pattern of activity enabled by a systematic organization of resources, defined roles and mass, energy and information flows, into a work process that can be documented and learned. ... This article is about data structure encoding. ...

XAML elements can map directly to Common Language Runtime (CLR) object instances whereas attributes can map to CLR properties and events on those objects. In typical usage, XAML files will be produced by visual design and developer tools, such as Microsoft Expression Blend, Microsoft Visual Studio, XAMLPad or the hostable Windows Workflow Foundation (WF) visual designer.

XAML files are sometimes compiled into a .baml binary files, which may be inserted as a resource into a .NET Framework assembly. At run-time, the framework engine extracts the .baml file from assembly resources, parses it, and creates a corresponding WPF visual tree or workflow. The Microsoft . ... A workflow is a reliably repeatable pattern of activity enabled by a systematic organization of resources, defined roles and mass, energy and information flows, into a work process that can be documented and learned. ...

When used in WPF, XAML is used to describe graphically rich visual user interfaces, such as those created by Adobe Flash. XUL, GladeXML and UIML are other examples of XML-based user interface languages. WPF allows for the definition of both 2D and 3D objects, rotations, animations, and a variety of other effects and features. This subsystem is a part of . ...

GladeXML is the XML format that the Glade Interface Designer uses to persist its forms. ... UIML stands for User Interface Markup Language. ...

When used in Windows Workflow Foundation (WF) contexts, XAML is used to describe potentially long-running declarative logic, such as those created by process modeling tools and rules systems. RuleML and BPEL are other examples of XML-based declarative logic languages. This subsystem is a part of . ...

Anything that is created or implemented in XAML can be expressed using a more traditional .NET language, such as C# or Visual Basic.NET. However, a key aspect of the technology is the reduced complexity needed for tools to process XAML, because it is simply XML. As a result, a variety of products are emerging, particularly in the WPF space, which create XAML-based applications. As XAML is simply based on XML, developers and designers are able to share and edit content freely amongst themselves without requiring compilation.

Example

This example shows a Hello World text in the top-level XAML container called Canvas.

 <Canvas xmlns="http://schemas.microsoft.com/client/2007" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"> <TextBlock>Hello World! </TextBlock> </Canvas>

The MySilverlight.js must contain the code that loads the above XAML code (as a XML file) code under the MySilverlight html element.

Criticism

With XAML, critics, for instance ECIS, fear that Microsoft aims to introduce content on the web that can only be served from the Windows platform. They argue that XAML is positioned to replace the cross-platform HTML standard. Effectively, once XAML usage becomes widespread enough, users will risk having to purchase Microsoft products to access web content,^[3] however, XAML is cross-platform by design and cross-platform implementations do exist for example eFace for Java.^[4] The European Committee for Interoperable Systems (ECIS) is an international non-profit association founded in 1989 in order to promote interoperability and market conditions in the ICT sector allowing vigorous competition on the merits and a diversity of consumer choice. ...
