The growth of the Web of Data (WoD) has primarily been funded by subsidies. New datasets are financed via public funding or research programs. This may eventually limit the growth and could hamper data quality for lack of clear incentives. We propose MaTriX , a market-based SPARQL broker over the WoD as an economically viable growth option. Similar to others, queries are associated with a budget and minimal result-set quality. The broker then employs auction mechanisms to find a set of data providers that jointly deliver the results. Preliminary results shows that mixing free and commercial providers exhibits superior: consumer surplus, producer profit, total welfare, and recall.
