Michael Chui, Diana Farrell, and Kate Jackson: “Institutions and companies across the public and private sectors have begun to release and share vast amounts of information in recent years, and the trend is only accelerating. Yet while some information is easily accessible, some is still trapped in paper records. Data may be free or come at a cost. And there are tremendous differences in reuse and redistribution rights. In short, there are degrees when it comes to just how “open” data is and, as a result, how much value it can create. While businesses and other private organizations can make more information public, we believe that government has a critical role in unleashing the economic potential of open data. A recent McKinsey report, Open data: Unlocking innovation and performance with liquid information, identified more than $3 trillion in economic value globally that could be generated each year in seven domains through increasingly “liquid” information that is machine readable, accessible to a broad audience at little or no cost, and capable of being shared and distributed. These sources of value include new or increased revenue, savings, and economic surplus that flow from the insights provided by data as diverse as census demographics, crop reports, and information on product recalls.”
