  This paper begins the discussion of how the Information Flow Framework can be
used to provide a principled foundation for the metalevel (or structural level)
of the Standard Upper Ontology (SUO). This SUO structural level can be used as
a logical framework for manipulating collections of ontologies in the object
level of the SUO or other middle level or domain ontologies. From the
Information Flow perspective, the SUO structural level resolves into several
metalevel ontologies. This paper discusses a KIF formalization for one of those
metalevel categories, the Category Theory Ontology. In particular, it discusses
its category and colimit sub-namespaces.
