I created an XMI version of the task meta-model diagram, you can find it at

It was automatically generated by the Visual Paradigm tool, and it is 
full of weird ids. I don't think this is a problem if the diagram is 
read by a tool, but I think that it is better to provide a text 
description using a bullet lists or a table, maybe inserting also links 
between the related model entities.
