Most schema languages rely on regular grammars for specifying schema constraints, a fundamental paradigm in the design of these languages. The one exception is Schematron, produced by Rick Jelliffe. Schematron throws out the regular grammar approach, replacing it with a rule-based system that uses X

After suggesting that UIDs should be attached to elements to leave the choice of their names and language up to application designers, the debate on ebXML mailing lists has expanded to cover many points often discussed on XML forums — including the need for universal "names", the readabilit

Message transfer of e-business applications struggled in the past due to incompatible component models such as CORBA and COM, as well as complex, competing message standards such as ANSI-X.12 or EDIFACT. XML lowers these traditional barriers because all you need for processing is an XML parser. XML

Vijay Kukreja writes a small Java program which uses Xalan and shows us how simple it is to do XML transformation. In the Part I he explains the problem and helps getting things ready. Part II focuses on the Java program and the input XML file. And in the final Part III the XSL file is explained lin

Using XML with Java is amazingly simple: All you need is a JDK, some free class libraries, a text editor and some data to process. The Document Object Model (DOM) is a popular, standardized way of manipulating XML data. Java developers might prefer JDOM in the future,a more Java-oriented API for rea

Xparse-J aspires to be the smallest Java XML parser on the planet. Xparse-J favors compactness over conformance, so it is mainly useful for being embedded in Java applets for simple XML processing tasks, such as parsing RSS as demonstrated in RSSApplet.

As the world is codified one schema at a time, what are the consequences and implications? This first half of a two-part essay examines why schemas are essentially political.
