Why is XML important?

XML describes data. This data can be processed.

XML data can be:

• stored
• exchanged in a neutral, self-documented way
• extracted and re-used
• updated
• displayed in various ways (write once, published many times)
• when all else fails it can still be accessed using vi

XML provides a standard, well-defined, layer on top of which applications can be built.

XML allows the definition of interfaces between loosely-coupled applications.

the hierarchical (tree) model is very powerful.

XML comes with many tools.
