Our work at Quoin includes multinational and global organizations, and often requires that web, mobile, and enterprise applications can be customized for specific languages. In particular, the Primero platform has this requirement given its widespread use in Latin America, Asia, and Africa. This presentation examines the process and tools for internationalization and localization. Internationalization is the process of extracting strings and other elements that vary by location. Similarly, localization involves the customization of these elements so an application can be customized for a specified locale.
