One of the problems facing federated database management systems is how to handle change among entities in the federation. Change can occur when a new site is added to the federation, a new set of security privileges is introduced, or one of the schemas has been modified. One powerful mechanism for constructing an adaptive federated architecture is metadata. Mowbray [MZ95] describes metadata as self-descriptive definition of services and information. In this article we present our ideas for modelling federation metadata in the LIOM project.
