[ddia.vonng.com](https://ddia.vonng.com/) publishes *Designing Data-Intensive
Applications* as a multilingual book. The case snapshot includes 24 chapters
each in Simplified and Traditional Chinese, 23 chapters of the English second
edition, and two 21-chapter first-edition sets.

## What it demonstrates {#what-it-demonstrates}

- A complete `type: book` reading shell with chapter-level navigation.
- More than 130 numbered figure, table, equation, and example targets.
- Stable cross-references and generated book indexes across several editions.
- Multiple written-language variants inside one publication.

Use this pattern for long-form works where numbering, citations, and movement
between chapters matter more than documentation-style sidebars.
