What is AppML?

• AppML stands for Application Markup Language
• AppML uses XML to describe data
• AppML uses XML to describe applications
• AppML uses XML to exchange data
• AppML applications are self describing.
• AppML is an open source initiative
• AppML is initiated by Refsnes Data

Why an Application Markup Language?

Why do we need an Application Markup Language?

• Create platform independent applications
• Create compile free applications
• Create expandable applications
• Create distributable applications
• Reach a larger audience
• Reduce our development costs
• Use vendor independent Web standards
• Use thin browser clients

AppML Design Goals

The design goals for AppML have been:

• AppML must run straightforwardly over the Internet
• AppML must use Internet standards only
• AppML must be completely platform independent
• AppML must be compatible with XML and XHTML
• AppML must support a variety of application needs
• AppML must be self describing
• The specification must be short, formal and concise
• Optional features must be kept to a minimum, or zero
• AppML applications must be easy to develop
• AppML applications must be easy to maintain
• AppML applications must scale gracefully
• AppML applications must be future proof

Important AppML Notes

AppML is not a programming language. AppML is used to describe applications.

AppML uses the Internet standards XHTML and XML.

Traditional applications are precompiled, with predefined data structures and predefined functions, while AppML allows the programmer to redefine both data, and functions while the application is running.

AppML is also ideal for extremely rapid prototyping.
