ABSTRACT
Due to the recent growth of the World Wide Web, numer-
ous spatio-temporal applications can obtain their required
information from publicly available web sources. We con-
sider those sources maintaining moving objects with prede-

perform queries on the integration of these data sources effi-
ciently. Examples of such data sources are networks of rail-
