Abstract:

The DITA-OT plugin transforms a map into a single file, suitable for publication, and automatically call the xmlrpc API of the blog to publish it. The DITA Wordpress plugin adds a css (a slightly modified version of the DITA-OT commonltr.css) to your Wordpress theme to properly render the standard domains.
