PSOA RuleML Integration of Relational and Object-Centered Geospatial Data

In recent years, many geospatial data sets have become available on the Web. These data can be incorporated into real-world applications to answer advanced geospatial queries. In this paper, we present a use case to integrate a local data set with external geospatial data sets on the Web. The data sets are modeled in different paradigms – relational and object-centered. The integration uses Positional-Slotted Object-Applicative (PSOA) RuleML, which combines the relational and object-centered modeling paradigms for databases as well as knowledge bases (KBs).
