"Locale" is a mechanism used by the Web, Java, and many other technologies to establish user interface language, data presentation formats, and for tuning application behavior to the cultural requirements of each user. Many application developers make use of locales and then presume their applications now have correct international behavior. How well do Locales work in actual practice? Our panel of experts will discuss their differing views on Locales, how Locales should and should not be applied, whether they work as expected, and whether alternatives should be considered. The panel format provides a forum for audience discussion that builds on the content of related papers being delivered at this conference.
