Abstract
In model management, the Merge operator takes as input a pair of schemas, together with a set of mappings between their objects, and returns an integrated schema. In this paper we present a new approach to implementing the Merge operator based on semantic mappings between objects. Our approach improves upon previous work by (1) using formal low-level transformation rules that can be translated into higher-level rules and (2) specifying precise BAV mappings, which merge schemas without any information loss or gain.
