At Semantic Arts, we recently decided to upgrade our internal system to turn something that was a not temporal (our billing rates) into something that was. Normally, that would be a pretty big change. As it turned out, it was pretty straightforward and could be done, as an in place update. It turned out to be a pretty good mini case study for how using semantics and a graph database can make these kinds of changes far less painful.
So, Dave McComb documented it in a YouTube video.
