Package Metacontent & Guidance

  • Last Modified: 2019-04-10

Files and directories stored outside of the ZIP archive's /package directory are referred to as metacontent, and the upack.json manifest file is the only required metacontent in a package.

Unlike actual content, there is no "general purpose" usecase for metacontent. Instead, think of it as a tool to help you build a specification for a package format that is based on a universal package. For example, romp packages define several metacontent files and folders that are used to help install the /package contents.
