Hi Guys, Many years ago I made a drawing showing how libgeda represented a schematic. The representation was doubly-linked lists of OBJECTS, ATTRIBs, etc. The drawing is here: http://www.brorson.com/gEDA/gEDA_Structures_20050108.pdf I don't know how much (or how little) things have changed since then, but perhaps this drawing might be of use?
