Using sparql2sql in Practice

PiSmartHome

PiSmartHome is an application that uses the queries from the Smart Home Analytics Benchmark within a web-based interface for descriptive and diagnostic analytics. It uses D3.js to visualise over time temperature and energy usage as per the benchmark queries. Translation from SPARQL to SQL is performed using the sparql2sql-server.
