It is also up to the application providing the data. Between the two,
they can negotiate a desired exchange format for the data.

I was looking to finish refactoring the cairo drawing routines, and be
able to export arbitrary graphics formats which cairo knows how to
stream. (That is pdf, png, postscript, svg, and WMF / EMF o Win32).


When you're talking about transfer to the board layout, one or the other
end will need to know how to invoke gnetlist and do the right thing with
the data. Since the piece of schematic you're copying might be nested
within a hierarchy block, that does make things more complicated.

Realistically, I don't expect to see copy-paste between schematic and
board layout any time soon. It's getting to the edge of what fits the
physical copy+paste UI metaphor. Drag/drop would also be a stretch.
