3 Meta-Ontological Architecture of GFO

GFO has a three-layered meta-ontological architecture comprised of (1) a basic level consisting of all relevant GFO-categories, (2) a meta-level, called abstract core level containing meta-categories over the basic level, for example the meta-category of all categories, and finally, (3) an abstract top level including set and item (urelement) as the only meta-meta-categories.
