  So far, the Web of Data (WoD) has only marginally considered the problem of financing itself. In most of the cases, research funds (either public or private) and donations are supporting the creation and maintenance of WoD services. Applying typical Web financing mechanisms to the WoD is not straightforward, since the machine-processable nature of the WoD introduces new challenges. For example, users may access the data through applications that filter out advertisement. We believe that delayed-answer auctions are a possible way to overcome such a problem: when a user submits a query, the SPARQL endpoint serves the answers in sequence of batches. Behind the scenes, sponsors bid to increase the chances that data they are interested in promoting appears at the beginning of the sequence. In this demo, we show how this delayed-answer auction can be realized. We built a scenario where users can query for restaurants in New York City and restaurant owners act as sponsors.
