FedShop - Hackathon

Hackathon # Organization data/<br> | virtuoso.ini # The template configfile for Virtuoso 7.2.7<br> | virtuoso_batch_*.db # The dump of Virtuoso for 2 batches. Batch 0 contains 10 vendors and 10 rating sites; Batch 4 contains 50 vendors and 50 rating sites.<br> | batch_*.nq.zip # Compressed file containing NQuads for given batch 0/4<br> | fedx_batch_*.conf # FedX federation members declaration for batch 0/4.<br> queries.txt # List of federated queries following the BSBM explore use case. # What does each batch contain?<br> - We generate data using BSBM schema.<br> - Batch 0 contains 10 vendors and 10 rating sites; Batch 4 contains 50 vendors and 50 rating sites.<br> - Each source is stored in dedicated named graph, i.e "http://localhost:8890/sparql/?default-graph-uri=www.ratingsite{0..49}.fr" or "http://localhost:8890/sparql/?default-graph-uri=www.vendor{0..49}.fr". # How to use it<br> - Start Virtuoso v7.2.7 with the desired batch, i.e, virtuoso_batch_4.db and update virtuoso.ini.<br> - To obtain expected results, simply execute any given query in queries.txt directly on Virtuoso.<br> - Start RDF4J's FedX with corresponding config file, i.e, fedx_batch_4.conf.<br> - Run any query in queries.txt<br> - The NQ files are dumps of virtuoso_batch*.db. They could be used for ingesting in other datastores or to build indexes.
