(b) If the domain of DP is a DI and its range is a set of classification data, apply the following combination
of mapping patterns. First, use the classification property pattern to create a separate DC for each possible
DP value. Second, use the property chain pattern to specify the path between the DI and the described PO.
Third, extend the DCs using the structural descriptor and the multivalued descriptor to specify the required
structure (by concrete OPs) and concrete DPs of their POs.
