Sophie

http://sophieproject.org/

• According to the site, Sophie is written in Java, but is used in Pier application MobileWikiServer.
• Sophie is a FOSS collaborative multimedia "book" authoring system. Updates are instantaneous (no edit conflicts or merges) and multiple authors can collaborate on the same book simultaneously. (Educated guess: uses XMPP)

Note: From the Using Sophie Server video, it appears that Sophie Server is merely Pier, and that Sophie Author and Sophie Reader are Java apps.

• Sophie Author allows users to create complex networked multimedia documents without specialized training.
• Sophie Reader allows readers to read Sophie books in a browser without downloading a separate application.
• Comment frames allow easily constructed spaces for discussion inside of books.
• Browser frames allow embedding fully functional web browsers in book pages.
• Sophie can import, embed, and export PDF files.
• Easy to use embedded books: Sophie books can open inside other Sophie books.
• Frame-based timelines present an easy way to create animations.
• Sophie Server allows uploading, managing, and downloading books on a server.
• Sophie Server allows simultaneous collaborative creation of books.
