I know one place where the DFM and assembly (PnP programming, flying probe, whatever) exclusively use ODB++.
Easy enough to generate from any enterprise-grade software, but may not be available in lower tier and free software.
The format looks easy enough to reverse engineer (it's plain text ASCII, organized by folders, wrapped up in a .tgz), but I don't know if anyone's done the work. Apparently, the companies behind it don't want an open implementation...
