The Clio project is a joint project between the IBM Almaden Research Center and the University of Toronto begun in 1999. Clio's goal is to radically simplify information integration, by providing tools that help in automating and managing one challenging piece of that problem: the conversion of data between representations. Clio pioneered the use of schema mappings, specifications that describe the relationship between data in two heterogeneous schemas. From this high-level, non-procedural representation, Clio can automatically generate either a view, to reformulate queries against one schema into queries on another for data integration, or code, to transform data from one representation to the other for data exchange.
