This document summarizes Enel's open data initiative to publish linked data about their electric vehicle charging network. It discusses how Enel publishes data about charging stations as linked open data, links the stations to external datasets like Geonames, and experiments with adding real-time occupancy data. It also shows how natural language queries can be used to ask meaningful questions about the charging network using SPARQL.

18. …WHY
?
• Having Consumers GeoTag and Recommend their favorite
charging stations (like the City of Paris did for its bike sharing
Vélib’)
• Having Consumers Share where they go charging using their
EV
• Providing suggestions on charging locations based on
friends’ check-ins (converting foursquare data in RDF)
• Engaging with Consumers to encourage the adoption of
eMobility
