Repo-PlantUML-Dataset: A Real-World Repository-Derived Collection of PlantUML Files

The Repo-PlantUML-Dataset is a curated collection of 1,026 real-world PlantUML diagram files extracted from 68 public GitHub repositories across 13 programming languages. Unlike synthetic UML datasets, this collection preserves authentic diagram styles, structural complexity, and naming conventions. Each repository includes metadata such as language, stars, forks, watchers, repository size, and creation/update dates. The dataset is suitable for research in UML diagram analysis, automated diagram generation, architecture recovery, and machine learning applications. All files respect original licenses and are publicly available.
