Few designers explicitly think about their applications' interrelationships
. Designers appear not have a deep enough conceptualization of their domain
s to identify intuitive relationships and realize the full scope and interc

igners and developers an analysis tool to think about an information domain
in terms of its interrelationships. RNA incorporates a complete taxonomy o
f generic relationship types that would apply to any application domain.
