<b>update:</b> my ascii drawing corrupt with threaded view. please have a look from single article view.<br><br>
Thanks for reply. This is too interesting for me.<br><br>
I used extends here, not with, like you always do. Roles, mixins are new to me. <br>
I guess this picture vaguely like this.

So, your generic object should know the dependencies of roles to use, plugging them , create the output. Dependencies varies from case by case, you have to use roles dynamically, with apply_all_roles. <br><br>
From client, it will just look like google api, tell the pipe line parameters needed with HTML header, or sending XML.<br><br>
