modid

A modid, short for mod identifier, is a string used to uniquely identify a mod within a modding framework or game. It serves as a namespace for resources, content, and configuration, helping to prevent conflicts between different mods and the base game.

In Minecraft modding environments such as Forge and Fabric, the modid is central to how a mod is loaded and referenced. It is typically defined by the mod author in the mod’s metadata and is used as the namespace for many game assets. Asset files, such as textures and language files, are usually organized under a folder named assets/[modid], and game content registered by the mod often uses the modid as part of the resource location, for example modid:path. The modid thus links code, data, and game content together within the modding framework.

Naming and maintenance guidelines are commonly recommended to ensure compatibility and avoid conflicts. Modids are generally lowercase and may include digits and underscores. They should be unique within the modding environment and kept stable across releases to prevent breaking references in existing worlds or other mods. Changing a modid after release can create missing references and data migration challenges.

In addition to its use in resources and registries, the modid is distinct from a mod’s display name. The display name is user-facing, while the modid is a programmatic identifier used by the game, tools, and other mods to reference the mod reliably.
