dataLib

dataLib is a mod framework for Minecraft Java Edition datapack developers. It provides a structured macro execution system, modular API modules, and multi-version compatibility — no mods required.

Multiplayer-Safe	No global state conflicts — designed for concurrent player use
Permissions	Built-in datalib:api/perm module for role-based access control
