I certainly agree that much of the ontology is implicit in the data 
structures.  But I would add that it's possible to relate those
data structures to other languages.    (02)

In particular, I'd like to mention a successful application to
legacy re-engineering.  It involved analyzing COBOL programs that
were up to 40 years old and had gone through many modifications
and updates over the years.  The company also had documentation
of various kinds -- reports, manuals, notes, emails, etc.    (03)

The problem was to analyze both the programs and the documentation
relate them to each other, detect errors and inconsistencies, and
generate a glossary, data dictionary, etc.    (04)

A major consulting firm estimated that the project would require
40 people for 2 years to read all the documentation and relate
it to the software and the databases.  But with suitable computer
analysis, the project was completed in 15 person weeks.    (05)

(Just type 104 into the page window of the Adobe reader to jump
to slide 104.)    (08)
