  Faceted classifications define dimensions for the types of entities included.
In effect, the facets provide an "ontological commitment". We compare a faceted
thesaurus, the Art and Architecture Thesaurus (AAT), with ontologies derived
from the Basic Formal Ontology (BFO2), which is an upper (or formal) ontology
widely used to describe entities in biomedicine. We consider how the AAT and
BFO2-based ontologies could be coordinated and integrated into a Human Activity
and Infrastructure Foundry (HAIF). To extend the AAT to enable this
coordination and integration, we describe how a wider range of relationships
among its terms could be introduced. Using these extensions, we explore richer
modeling of topics from AAT that deal with Technology. Finally, we consider how
ontology-based frames and semantic role frames can be integrated to make rich
semantic statements about changes in the world.
