Abstract: With the ever-growing availability of so-called complex data, especially onthe Web, decision-support systems such as data warehouses must store andprocess data that are not only numerical or symbolic. Warehousing and analyzingsuch data requires the joint exploitation of metadata and domain-relatedknowledge, which must thereby be integrated. In this paper, we survey the typesof knowledge and metadata that are needed for managing complex data, discussthe issue of knowledge and metadata integration, and propose a CWM-compliantintegration solution that we incorporate into an XML complex data warehousingframework we previously designed.
