So you don't want to use Dia's internal model (diagram, layers, objects)?

BTW: what's an "outside plugin"? Something not included with standard Dia?
Or something running outside of Dia? Or without Dia?

Sorry I don't understand the architectural model you have in mind. It might 
be either developing a plugin for Dia or ripping out some subset of Dia 
functionality to be reused in another application. What would you be 
"forking into another project"?

There are Dia plugins controlling what Dia is displaying called renderers. 
Other Dia plugins are able to create and modify diagrams - e.g. import 
plugins, but also the recently added layout plugin.
And on the core of all there are object plugins providing the building 
blocks for diagrams, mapping properties to recipes for drawing.

As I said I'm uncertain about what you are looking for, but neither 
enabling external (as in out of tree) plugins nor prodividing a diagramming 
library are partcular high on my own personal list.
