A growth of internet technologies and a broad range of information sources, used in organizations, libraries and scientific centers, lead IT researchers to develop new models, methods and tools for data integration. The necessity in heterogeneous information sources integration, such as relational and object databases, bibliographic collections, Web servers and information retrieval (IR) systems, becomes clear. The approach used in our project is based on the mediator architecture, to which heterogeneous data collections are attached via wrappers. In the article, we discuss the aspects of information retrieval systems integration. The procedure of new collection’s registration, and an approach for construction of bibliographic IRS wrappers are also shown using the example of IR system IRBIS. A component-based architecture of the wrapper, wrapper’s functions, and mapping of the mediator’s query language and type system, based on the SYNTHESIS data model, into IRBIS are described.
