The Web can be considered a single application, all parts of which must work together. To be a world wide web, these parts must work for every country, language, and culture. Internationalization is important to ensure that users worldwide can equally benefit from Web technology.

This tutorial will give an introduction to internationalization on the World Wide Web. The audience will learn about the standards that provide for global interoperability and come away with an understanding of how to work with multilingual data on the web.

Character representation and the Unicode-based Reference Processing Model is described in detail. HTML, XML (eXtensible Markup Language; for general markup), and CSS (Cascading Style Sheets; for styling information) are given particular emphasis. The tutorial addresses language identification, the character model, presentation features (ruby, bidirectionality, number formatting, sorting) and more. The design and implementation of multilingual Web sites and localization considerations are also introduced.
