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.
<oXygen/> is a complete cross platform XML editor providing the tools for XML authoring, XML conversion, XML Schema, DTD, Relax NG and Schematron development, XPath, XSLT, XQuery debugging, SOAP and WSDL testing. The integration with the XML document repositories is made through the WebDAV, Subversion and S/FTP protocols. <oXygen/> also supports browsing, managing and querying native XML and relational databases. The <oXygen/> XML editor is also available as an Eclipse IDE plugin, bringing unique XML development features to this widely used Java IDE.
