Domain schemata

The domain model for ESC contains the following types of information:

0pt 0pt

• Problem, solution pairs; mapping from a point in the source space to a point in the solution space.

• Extrapolation information: pairs of problem attribute differences, solution attribute modifications.

• Applicability zones (regions) of the different cases.

The following operations are directly supported by the domain model:

1. region-op(Case:case, Region:region).

   Represents the association between a case and the region of applicability.

2. source-problem-op(Case:case, Problem:attribute*)

   Associates a source problem with a case.

3. source-solution-op(Case:case, Solution:attribute*)

   Associates a source solution with a case.

4. adjustment-op(Problem-attribute:attribute, Solution-attribute:attribute*, --Adjustment:)

   Associates a problem attribute with a (set of) solution attribute(s) and a procedure to adjust the value of source solution to the problem.
