This paper contains a description of an architecture
for semi-formal systems that has developed over
a period of over ten years.

The architecture has been implemented in a variety
of prototype systems that have had varying amounts
of usage during that period.

The main features of the architecture allow
increased functionality, interoperability,
and consistency of applications,
while not constraining the development
of specialized systems to meet specific needs.
