The classes alone will not provide enough information to answer the competency questions
from Step 1. Once we have defined some of the classes, we must describe the internal
structure of concepts.
We have already selected classes from the list of terms we created in Step 3. Most of the
remaining terms are likely to be properties of these classes. These terms include, for
example, a wine’s color, body, flavor and sugar content and location of a
winery.
