For most of this questions LDStructure should be your friend 
My personal feeling is that we should use for connectivity the -already working- implementation from SR3D. I did not looked deep into this matter, but that connection information should be stored in a separate file with the same naming except the extension.
By doing it this way we can keep and work on the library as usual and create the connection data in a separate step (parallel or afterwards). I liked the way I could create the connectivity with LD4DStudio, but it was a too mighty tools in my stupid hands.
