Outline

Stefan Strobl & Martin ReitererResearch Group for Industrial Software (INSO) | Faculty of Informatics | Vienna University of Technology

We aim to make the concept of Java Internationalization more convenient

for agile software development projects.

Mission

Stefan Strobl & Martin ReitererResearch Group for Industrial Software (INSO) | Faculty of Informatics | Vienna University of Technology

Concept for building multilingual software:

– Separate culture-sensitive content

– Culture-sensitive resources are provided in multiple translations

Internationalization

Stefan Strobl & Martin ReitererResearch Group for Industrial Software (INSO) | Faculty of Informatics | Vienna University of Technology

Results in one single version of software:

– Reduces effort of maintainance, support and evolution

– That can dynamically adopt its output language

– Support for new cultural regions can be added by plugging in new resource translations.

Why Internationalization?

Stefan Strobl & Martin ReitererResearch Group for Industrial Software (INSO) | Faculty of Informatics | Vienna University of Technology

Problems in Practice

1. Internationalization increases the complexity of development and the resulting product

2. Requires well-founded knowledge of cultural differences

3. Needs to be lived by the entire development team

4. It‘s hard to keep language specific artifacts up-to-date

Stefan Strobl & Martin ReitererResearch Group for Industrial Software (INSO) | Faculty of Informatics | Vienna University of Technology

Typical Faults 1/3

Hard coded constant string literals within source code

Translation requires source code changes. Only one language per version of the source file possible

constant string literal

Stefan Strobl & Martin ReitererResearch Group for Industrial Software (INSO) | Faculty of Informatics | Vienna University of Technology

Typical Faults 2/3

Reuse externalized string literals in different contexts

Meaning of phrases depends on contextual information

Example:to focus to concentrate to focus to zoom in on sth.

Typically, it‘s hard/impossible to find a translation that covers all contexts!

Stefan Strobl & Martin ReitererResearch Group for Industrial Software (INSO) | Faculty of Informatics | Vienna University of Technology

Incomplete Internationalization of program sections

High effort in refactoring! Hard to detect through testing.

Typical Faults 3/3

constant literal

externalized literal

Roadmap

Replacing the current Resource-Bundle editor Licence TapiJI under Eclipse Public License (EPL)

Increase openness and extensability for– Easily enhancing support for new editors– Add new context-sensitive smart helps

Involving the community for:– Getting feedback about the current work– Cooperatively working on new ideas

Stefan Strobl & Martin ReitererResearch Group for Industrial Software (INSO) | Faculty of Informatics | Vienna University of Technology

Involving the Community

Open sourcing and hosting at EclipseLabs
