Status of the Sandbox Components

Check the status of a sandbox component on the sandbox wiki page or just ask on one of the commons mailing lists.

A Sandbox component is considered active if there is a definite plan for promotion to the Commons Proper and there is an active group of existing committers working on a component.

A Commons Sandbox component is considered dormant if there is little recent development activity and no individual or group of individual commiters has emerged to champion its ultimate promotion to Commons Proper. See the Commons dormant components webpage for a list of Commons components currently considered dormant.

A Commons Sandbox component is considered inactive if there is no active development for a sustained period of time.
