Getting Help
Community Support
Besides eXist-db's extensive documentation, eXist-db has a large and active community of users and developers. The community uses mailing lists, chat, a wiki, and social media—to get and give help, follow the latest developments, and share tips and discoveries.
The book, "eXist: a NoSQL Document Database and Application Platform" is currently being printed and is available from O'Reilly.com.
The exist-open mailing list is the primary forum for asking questions and getting help. Finding the answer to a question can sometimes be as simple as searching the mailing list's archives. Whether you have a question that you can't find the answer to, or you just want to join the discussion, subscribe to the mailing list—it's free and you can unsubscribe anytime.
Please consult this page for tips how to best report issues.
Besides exist-open, there is a mailing list dedicated solely to the XQuery language: the xquery-talk mailing list. It's a great place to ask questions about XQuery, from basic to advanced.
Also, there are numerous excellent resources for learning XQuery, including the XQuery wikibook and Priscilla Walmsley's XQuery book (O'Reilly 2007).
