Enable multilingual user interface support
Description
Simpl-Open shall provide the mechanism to support multilingual user interfaces by externalising all static translatable content and implementing a user-facing language selection feature. English will remain the default and only fully supported production language. Multilingual readiness will be demonstrated by including a minimal set of translations (English + one EU official language) for testing and validation through successful UI rendering tests.
It is assumed that texts are static: plural forms, gender-specific phrasing or context-sensitive translations are not dynamically adapted.
This includes the externalisation of all interface text, the implementation of dynamic language selection mechanisms, and the integration of translation workflows into the development and deployment pipeline.
This initiative aligns with EIF Underlying Principle 9: Multilingualism, which emphasises that European public services must be accessible to users across Member States and should reflect the linguistic needs of the expected audience.
SMART Breakdown
- Specific: All UI components must support translation via external language files. The system shall dynamically select the appropriate language based on user input or browser settings.
- Measurable: One additional EU official language must be demonstrably supported through a subset of translated UI content.
- Achievable: Multilingual support will be implemented using internationalisation libraries compatible with the frontend stack (e.g., i18n), and maintained through standard translation file formats (.json, .po).
- Realistic Modern frontend frameworks provide built-in support for multilingual interfaces. This initiative can be delivered without significant impact on development timelines when integrated into early design stages.
- Timely: Multilingual capabilities shall be available for all public-facing components before production go-live and maintained through continuous integration workflows.
