In this report we study temporal conceptual schema evolutions related to reification, a typical and complex modeling construct.
Various kinds of reification are considered. Using a previously defined framework, we specify, only at conceptual level (and
without descending to logical nor application levels), the effects of any possible evolution related to reification, thus reducing the
complexity of the management of those changes.
