Connecting the dots – Web Accessibility through Internationalization and Localization
2025年8月10日 , TR212

In the open-source and global ecosystem, digital (web/mobile) projects must be designed to serve users across languages, cultures, and abilities. This talk delves into how internationalization (i18n) and localization (l10n) complement web accessibility (a11y) standards to create truly inclusive digital experiences—leveraging open-source technologies, libraries, and best practices.

Attendees will gain insights into:
Internationalization: The technical foundations necessary for adapting content for any language or culture, including character encoding, RTL/LTR design, and internationalized code structures.
Localization: The process of tailoring a product to meet specific cultural, linguistic, and regulatory requirements, such as translating content, modifying UI elements, and adapting formatting conventions.
Web Accessibility: Ensuring that web content is robust and accessible to users with disabilities across different locales, focusing on the intersections between i18n, l10n, and accessibility standards (WCAG).

Key Takeaways:
- How open-source frameworks (e.g., React Intl, Fluent, Format.js) and community-driven projects facilitate i18n, l10n, and a11y.
- Lessons from global brands (ikea, pixar, etc) and OSS projects that integrate multilingual and accessible design.
- Best practices for creating adaptable, inclusive web applications with minimal rework.

Target Audience:
Open-source contributors, frontend developers, UX designers, accessibility advocates, and anyone passionate about making the web more inclusive through OSS.
