The 6th step of the wizard packager allows you to define which mimetypes 
are associated with your program.

Alas, there is nothing to define a new mimetype, which is needed to make 
the system aware of the *.myfile extension.

All the information is there:

http://freedesktop.org/wiki/Specifications/shared-mime-info-spec

A new mime type can be defined by running the 'xdg-mime install xxx.xml' 
command where 'xxx.xml' is an XML file that defines how to identify the 
mime type.

The syntax of that xml file is defined there:
