Schema Evolution publication categorizer

This paper presents an intermediate meta-model that consists
of a set of generic meta-classes that capture and describe
the semantics of a variety of data models. A model is
described by a set of intermediate model meta-classes (organized
in the form of a directed acyclic graph (DAG) to
achieve extensibility y), while irtst antes of these meta-classes
are used to describe a schema in a given data model. The
proposed approach supports dynamic meta-schema comparison
and transformation by employing special-purpose transformation
rules.
