AtomicWiki is entirely based on the Atom Publishing Protocol and syndication format. All entries are stored as Atom feeds. The Atom Publishing Protocol is used to create and manipulate feeds and entries. The entire system is implemented in XQuery and XSLT with the help of some Javascript for the AJAX goodies (like in-page comment editing). What makes the software really powerful is its tight integration with XQuery and XML databases. Macros and extensions to the wiki syntax are implemented as XQuery functions. XQuery code can also be directly embedded into an Atom entry to generate dynamic content. The eXist weblog is powered by AtomicWiki.
