A "rich client" is a compromise between the thin client and
the thick client. The purpose of the rich client is to provide a graphic interface,
written using an XML based syntax, which provides similar functionality to a thick client
(drag-and-drop, tabs, multiple windows, drop down menus).
Rich clients can also perform essential processing on the server side. Data is then sent using a
standard exchange format, using XML syntax (SOAP, XML-RPC), which is then interpreted by the rich client.
The principle standards which define a rich application are as follows:
- XAML (eXtensible Application Markup Language), pronounced "zammel", an XML standard developed by
Microsoft, and which is mostly used in .NET framework applications
- XUL, pronounced "zool", is an XML standard developed by Mozilla, used for example in the email client
Mozilla Thunderbird or in the browser Mozilla Firefox
- Flex, is an XML standard developed by Macromedia.
