Abstract
We discuss some weaknesses and limitations of an earlier semantic framework for the correctness of fragmentation schemes. For instance, this framework only supported conditional fragmentation based on single equality predicates. In order to solve these problems, we present a new meta model also allowing fragmentation based on a conjunction of less simple predicates.
