  2. Agenda • Introduction and motivation • Why develop multi language applications? • Problems and difficulties • Some good practices • Conclusion

  3. Why develop multi-lingual?

  4. Slovenia

  5. Some facts Slovenia Russia 10 billion 17.000.000 km2 $ 15.000 14 No Population: Area: GDP per capita: Neighboring countries: Played at the FIFA World Cup: • 2 million • 20.000 km2 • $ 25.000 • 4 • Yes

  6. Motivation and definition • Small country • Area with high cultural diversity • Focus on foreign markets • „Internationalization is a development process of content, applications and specifications in a way that ensures it will work well with, or can be easily adapted for, users from any culture, region or language.“ • [W3C]

  7. Bad practices • Separate applications for each language • Copy backend, change frontend • Only few applications support multi language natively • Drawbacks: • Time consuming • Hard to maintain • Different look and feel

  8. How to develop?

  9. Database • Different patterns for storing data • Attribute per language • Language identification by foreign key • Separate entities (independent, dependent and language) • Different alphabets • Latin • Cyrillic • Solution: Unicode

  10. Middle tier • Native support for multi-language and Unicode in all mayor application servers and runtimes (Java, Microsoft .Net) • Lack of support in application frameworks • Additional development of multi-language functionality • Adoption of services to provide different functionalities according to the user’s location • Difficult data retrieval and manipulation

  11. User interface • Most affected part of internationalization • Compositional changes • Incorporate images instead of plain text

  12. Templating frameworks • HTML generation based on templates using string substitution • Many free and open-source • A solution using XSL transformation

  13. Don‘t trust the browser • Many applications rely on the browsers‘ locale • Most of the time these are incorrect • Users are unaware of these settings • Develop fallback mechanisms to detect users’ languages

  14. What about AJAX? • AJAX = JavaScript + WebServices • Additional data about the language is needed • JavaScript templating frameworks Request Data

  15. Conclusion • An international web presence is crucial for businesses and organizations • Developing multi language web applications is a difficult job • Following some basic guidelines helps to reduce the difficulty • Plan additional time for content translation
