Extensible Markup Language (XML)

XML Filled a Growing Need

Proprietary (controlled) formatsProprietary (controlled) formatsand closed applications could not deal with growing complexity

XML: an Open Data Format for Open Systems

XML Enables Portable & Persistent InformationXML is only one (essential) y ( )part of the solution.

XML alone does notguarantee portability

The Importance of Validation

The rules governing documentshave grown more sophisticated.

Validity is in the eye of the consuming application...

The XML RevolutionXML sought more than anythingXML sought, more than anything, to enable content processability

Wellformed XMLi il f bli hiprimarily for publishing processes

Valid XMLfor more “data centric” processes

The success of processable XMLsparked a revolution in the way t h l li titechnology applications are designed, developed and deployed
