A federated information system requires that multiple (often heterogenous) information systems are integrated to an extent that they can share data. This shared data often takes the form of a federated schema, which is a global view of data taken from distributed sources. One of the issues faced in the engineering of a federated schema is the continuous need to extract meta data from cooperating systems. Where cooperating systems employ an object-oriented common model to interact with each other, this requirement can become a problem due to the type and complexity of meta data queries. In this research, we specified and implemented a meta data software layer in the form of a high-level query interface for the ODMG schema repository, in order to simplify the task of integration system engineers. Two clear benefits have emerged: the reduced complexity of meta data queries during system integration (and federated schema construction) and a reduced learning curve for programmers who need to use the ODMG schema repository
