Before Word integrated its own improved version tracking in more modern versions, during my undergrad I participated in a research project to add version tracking to Word documents by abusing its zip file format[1]. My research partner created a plugin to manage the versions, and my main contribution was a Java tool that attempted version merging[2].

It wasn't fleshed out or usable, but it was an interesting project. I was impressed at how open the Word/Office format was, this was before Microsoft's reemergence into openness and open source.
