Fediscount: dataset and summaries

Fediscount is a proof of concept for Web applications relying on configurable federations of SPARQL endpoints. It is an e-commerce Website where end users can browse a set of products and offers made available by a set of independent vendors.To facilitate the deployment process, here are the already ingested Fedshop dataset and summaries. For more details, please check out the Fediscount GitHub repository.The federation of endpoints is emulated by a Virtuoso endpoint (Version 7.2.6.3233-pthreads as of Jun 22 2021) where each endpoint has its own graph. By design, the database for 200 endpoints works for smaller configurations, i.e., for 20 and 100 endpoints as well (they are subsets of the former).The federation engine FedUP works with tiny summaries in Apache Jena's backend (TDB2): 

fedshop20-h0.zip summarizes 20 endpoints;

fedshop100-h0.zip summarizes 100 endpoints;

fedshop200-h0.zip summarizes 200 endpoints.
