Dia format uses a subset of svg 1.1 specification from W3C.

For the "static" ones you would author by hand or in an svg editor,  the 
easiest way is to follow the "custom shapes" chapter provided by the 
manual :)

In short, "custom shapes" are an svg 1.1 xml subset, which is embedded 
in a <shape> xml tag with, at option, one text tag.

For dynamic ones (what you have eg with lines or UML), the current way 
is C programming.

Any shapes set can be ~sorted in "sheets", which are also xml.

There are also a menu item in "save as" to export a diagram as a shape, 
and a button opening a toolbox to edit sheets.

This last method is limited to your "home" directory, especially for 
"sheets".

Best Regards, and good authoring,
