XML Schema Integration with Reusable Schema Parts

Modern information systems may exploit numerous XML formats for communication. Each message may have its own XML format for data representation which causes problems with integration and evolution of their schemas. Manual integration and management of evolution of the XML formats may be very hard. We tackled this problem in our previous work, however, for simplicity reasons, we omitted the possibility of exploiting reusable schema parts. In this paper, we complement our previous work with additional methods for schema integration which exploit reusable schema parts that quite often appear in XML schemas. This further helps a domain expert to get a precise mapping to a conceptual diagram, which then integrates the XML formats and facilitates their evolution a change that is made once in the conceptual diagram is propagated to the XML formats.
