It was a custom asset / reference system that I wrote a good few years back at Eurocom. At the time I wanted to use Maya asset system. I nearly used it, but found some killer bugs when duplicating assets. They basically kept loosing material assignments. Also as assets use the reference system I had issue's with CGFX shaders being loaded and complied time and time again. Slowing scene load times considerably. So I rolled my own system by using our metaData node / class. Inherited from the base class, hooked up to a db to track assets and versions (shotgun like) and rolled some utility methods for importing, updating, pushing edits back to source etc. It was something was bespoke for the way artists wanted to work at the time.
