We discuss Morpheus, a data transformation construction tool and associated repository. The architecture of Morpheus is motivated by the goal to reuse (pieces of) previously written transformations to solve data integration problems by finding relevant ones in the repository and then modifying them for repurposing. In addition, Morpheus is integrated with a DBMS so as to leverage existing capabilities including the runtime environment for transforms. We discuss the architecture of Morpheus and illustrate its usage with the help of a simple transform construction scenario.
