SILURIAN: a Sparql vIsuaLizer for UndeRstanding querIes And federatioNs

SPARQL federated queries can be affected by both characteristics of the query and datasets in the federation. We present SILURIAN a Sparql visualizer for understanding queries and federations. SILURIAN visualizes SPARQL queries and, thus, it allows the analysis and understanding of a query complexity with respect to relevant endpoints and shapes of the possible plans.
