Below is the schema of engine interactions:

Each plugins are indepentant and are here to generate thumbnails, previews, etc... Each previews, meta-data are cached in a cache directory to accelerate http queries. bonus: I have included in engine a handler that allows you to add comments per file, this behaviour does not require SQL databases because comments are saved in file's cache's meta-data.

If you want to see xml output without xslt processing, add "?xaiDebug=text" in your request. (you can put "?xaiDebug=xml", but your browser will do the xslt processing, so don't forget in this case to ask to view source)

Below is a sample of xml output

<?xml version='1.0' encoding='utf-8' standalone='yes' ?>
<?xml-stylesheet type='text/xsl' href='http://www.vanbelle.fr/.libs/themes/explode/template.xslt'?>
<autoIndex>
  <display mode='folder' format='' theme='explode'  />
