AdiumXMPPBookmarks is a plugin for Adium that implements XEP-0048: Bookmark Storage.

When connecting an XMPP account, Adium will attempt to retrieve all server-side bookmarks, add them locally and join them if they are set to autojoin. Edits to the bookmarks are pushed to the server.

Note: This is the older XEP-0049: Private XML Storage based version of XEP-0048. This means that editing the bookmarks from two different clients at the same time is not supported.
