Difference between organizations “rpm” and “pool” in “src.opensuse.org”

Hello, May I ask what are the differences between these two organizations in "src.opensuse.org"? They both have a similar package list. https://src.opensuse.org/pool https://src.opensuse.org/rpm/ By the way, will this old site continue to update? https://code.opensuse.org/group/package Thank you.
