[1][2] DGD pioneered important technical innovations in MUDs, particularly disk-based object storage, full world persistence, separation of concerns between driver and mudlib, runtime morphism, automatic garbage collection, lightweight objects and LPC-to-C compilation.
[7] During the 1994–1995 academic year, DGD was a core element in a master's thesis at the Katholieke Universiteit Leuven.
As part of the thesis work, a deterministic mechanism for handling arrays and mappings passed between objects was devised.
