DerivedCoreProperties are pseudo-properties that are the union of other categories and properties. For example, the derived property Math is the union of the general category Sm and the property Other_Math. Parsing these is necessary for implementing Unicode property escapes. But it also has the added benefit that LibUnicode now does not need to derive some of these properties at runtime.
