RELAX NG

In computing, RELAX NG (REgular LAnguage for XML Next Generation) is a schema language for XML - a RELAX NG schema specifies a pattern for the structure and content of an XML document. A RELAX NG schema is itself an XML document but RELAX NG also offers a popular compact, non-XML syntax. Compared to other XML schema languages RELAX NG is considered relatively simple.

It was defined by a committee specification of the OASIS RELAX NG technical committee in 2001 and 2002, based on Murata Makoto's RELAX and James Clark's TREX, and also by part two of the international standard ISO/IEC 19757: Document Schema Definition Languages (DSDL). ISO/IEC 19757-2 was developed by ISO/IEC JTC1/SC34 and published in its first version in 2003.

Schema examples

Suppose we want to define an extremely simple XML markup scheme for a book: a book is defined as a sequence of one or more pages; each page contains text only. A sample XML document instance might be:

XML syntax

A RELAX NG schema can be written in a nested structure by defining a root element that contains further element definitions, which may themselves contain embedded definitions. A schema for our book in this style, using the full XML syntax, would be written:

2004 Republican National Convention

The 2004 Republican National Convention, the presidential nominating convention of the Republican Party of the United States, took place from August 30 to September 2, 2004 at Madison Square Garden in New York City, New York. The convention is one of a series of historic quadrennial meetings at which the Republican candidate for President of the United States and party platform are formally adopted. Attendance included 2,509 delegates and 2,344 alternate delegates from the states, territories and the District of Columbia. The convention marked the formal end of the active primary election season.

The theme of the convention was "Fulfilling America's Promise by Building a Safer World and a More Hopeful America." Defining moments of the 2004 Republican National Convention include a featured keynote address by Zell Miller and the confirmation of the nomination of President George W. Bush and Vice President Dick Cheney for reelection. Bush and Cheney faced the Democratic Party's ticket of John Kerry and John Edwards in the 2004 presidential election.
