WSGIAppClient is simple middleware meant to provide a client interface to an Atom Publishing Protocol server offering a weblog profile. The interface is meant to mimic the functionality of the WordPress authoring environment.

The interface is built using XSLT and is a test bed for building web applications that focus on XSLT as a template language. This includes developing standards for passing parameters and node-sets to indicate messages, errors and any other necessary elements into a page.
