vascoda (www.vascoda.de) is today the most important project to
achieving a new innovative infrastructure in the field of scientific
information in Germany. The aim is to integrate high-quality information
from the deep and from the visible web by using search engine technology
(FAST) and new concepts to integrate the data, not only technically, but to
solve the problem of semantic heterogeneity at a high level of quality. In
contrast to the ontology and semantic web approach that of semantic
heterogeneity in the context of the shell model started from the invisible
web, opening itself to the visible, not vice versa, and is putting the reuse of
existing semantic knowledge (thesauri) in the foreground. The
consequences of these differences and the common features of both
approaches are in the focus of the paper
