We reach the conclusion that, from a strictly technical perspective, the classic role of the global catalog can be assumed in an ad-hoc manner by any catalog that forms part of a collaborative federation of XML-based catalogs, and implements our adaptive query algorithms, independently of the storage model used to access its contents.enE-CommerceE-CatalogCatalog integrationXMLXpathCatalog integration made easyText/Conference Paper1617-5468
