Depends on what version of Dia you are using. With 0.97-pre there is 
generic object metainfo. Just use:

        obj.properties["meta"] = {'mykey' : 'myvalue' }

which then gets stored and loaded with Dia's standard load/save.

Is this generate from PyDia? Maybe you can show some source?
(Given the recent increase in PyDia questions I wonder why there are no 
user provide PyDia plug-ins. Are you all just developing proprietary stuff?)

I don't understand this. Are you already using the meta facility?
