OpenMoji is an open-source emoji set maintained by HfG Schwäbisch Gmünd. The repository contains the full pipeline for producing emoji assets: source SVGs, a metadata generation system that merges emojibase-data with custom CSV enhancements and Unicode draft overrides, export scripts for color/black SVGs, PNGs, PDFs, and font generation via Docker. The central data file `data/openmoji.json` provides structured emoji metadata including hexcodes, tags, authors, and dates. The build system is modular with incremental caching, color palette enforcement using kd-tree, and comprehensive tests for data integrity, SVG layer rules, and font table presence. While primarily a data/research repository producing emoji assets, it includes a thin npm package for programmatic access and a sophisticated build pipeline that could be adapted for other icon sets. The repository is actively maintained with recent commits and CI workflows, though it relies on external dependencies like emojibase-data and a Docker font builder that may introduce drift.
