Freebase, a structured wiki-like database, should be of interest to anyone with an interest in web architecture and the quest for a semantic digital order. It uses a system of user-extensible types that allow contributors to build logical relations between topics rather than just linking and tagging them. Sounds simple? Freebase’s structure seems to introduce some pretty powerful descriptive possibilities. Freebase has just reached ‘alpha’ (open to public view, but not freely editable). I think it’s one to watch.
