Evolution of Knowledge Bases expressed in Description Logics (DLs) proved its importance. Most of studies on evolution in DLs have focused on model- based approaches to evolution semantics and in particular on Winslett's semantics (WS). It was understood that evolution under WS even in tractable DLs, such as DL-Lite, suffers from inexpressibility, i.e., the result of evolution cannot be expressed in the same logics. In this work we show which combination of DL-Lite logical constructs are responsible for the inexpressibility and explain reasons of such a behavior. We present novel techniques, based on what we called prototypes, to capture Winslett's evolution in FO[2] for two DL-Lite sub-fragments. We also discuss approximations of evolution results under WS in DL-Lite.
