Error when I create database extension

I was wondering how to create metadata.xml when I created the database extension. How to create the following through the eclipse xml file. Xml file is through what kind of process to get. I have Oracle11 to expand the package, I would like to create a mysql extension package based on it myself I do not know what to do?
