Level: Data Management - Intermediate

One of the latest solutions for collecting information from disparate data sources involves federated semantic queries. They offer many advantages over traditional solutions, ranging from non-disruptive, virtual data aggregation to domain-specific query capabilities. This presentation describes a semantic query architecture which decomposes SPARQL queries based on OWL domain and data source ontologies, SWRL ontology translation rules, OWL-S service descriptions and database mappings, to support federated semantic queries across multiple relational databases and/or web services. The implementation of such an architecture in a net-centric data sharing environment, as specified in the DoD’s 8320.02-G directive, will also be discussed.
