XML-based Data Integration for Semantic Information Portals

: This paper addresses some classical problems to integrate data sources that are heterogeneous in structure with possibly redundant data along a real world example integrating three bibliographic data sources. We show how XML-technology can be applied for the data integration process in a straight-forward manner to populate a data warehouse, how an ontology can be used as common schema, and how a generic, declarative approach can increase flexibility and scalability. Our procedure enables more advanced query functionality for integrated data sources.
