components. The Commons Proper is a place for collaboration and sharing, where developers from throughout the Apache community can work together on projects to be shared by Apache projects and Apache users.
Commons developers will make an effort to ensure that their components have minimal dependencies on other
software libraries

deployed easily. In addition, Commons components will keep their
interfaces as stable as possible, so that Apache users, as well as other Apache projects, can implement these components without having to worry about changes in the future.

Commons Sandbox
The Commons Sandbox provides a workspace where Commons contributors collaborate and experiment on projects not included in the Commons Proper. Commons members champion projects in the Sandbox for promotion to the Commons Proper, and groups of developers work to enhance Sandbox projects until they meet the standards for promotion.
Commons Dormant
The Commons Dormant is a collection of components that have been declared inactive due to little recent development activity. These components may be used, but must be built yourself. It is best to assume that these components will not be released in the near future.
