  ROSS ("Representation, Ontology, Structure, Star") is introduced as a new
method for knowledge representation that emphasizes representational constructs
for physical structure. The ROSS representational scheme includes a language
called "Star" for the specification of ontology classes. The ROSS method also
includes a formal scheme called the "instance model". Instance models are used
in the area of natural language meaning representation to represent situations.
This paper provides both the rationale and the philosophical background for the
ROSS method.
