The paper outlines 3 approaches to query federation: Receptor Explorer (Rob), AIDA (Scott), and FeDeRate (Eric). While the first two approaches involve querying RDF/OWL datasets (converted from different data sources), the third approach involves mapping SPARQL to SQL using SWObjects. I don't think any of these approaches use Jena adapter to map to relational databases. I may have missed something. If so, the developers of these approaches can chime in. -Kei Oliver Ruebenacker wrote: > Hello, > > Very nice!
