Welcome to FedX

FedX is a practical framework for transparent access to Linked Data sources through a federation. It incorporates new sophisticated optimization techniques combined with effective variants of existing techniques and is thus a highly scalable solution for practical federated query processing.

Core Features

• Virtual Integration of heterogeneous Linked Data sources (e.g. as SPARQL endpoints)
• Transparent access to data sources through a federation
• Efficient query processing in federated environments
• On-demand federation setup at query time
• Fast and effective query execution due to new optimization techniques for federated setups
• Practical applicability & easy integration as a RDF4J SAIL
• Comprehensive CLI for federated query processing from the command line
