This repository is a curated collection of traditional Chinese patterns organized as structured open data. It contains 100 high-resolution pattern images accompanied by detailed metadata (in JSON format) and Chinese-language description pages. The data is organized into six thematic categories (Flora, Fauna & Beasts, Geometric, Cloud-Water-Stone, Auspicious Objects, Characters & Composite) and aggregated into machine-readable JSON and CSV formats. Each pattern includes standardized metadata fields for identification, categorization, semantic description, and visual characteristics, along with cryptographic hashes for verification. The project serves as a cultural heritage resource for designers, researchers, and educators interested in traditional Chinese decorative arts.
