The Power of Open Data
This document discusses the power of open data and how making data available online can enable new applications and discoveries. It provides examples of how open government data allowed for the creation of apps like a gas pump inspection checker. The document also discusses how RESTful principles and APIs have allowed systems like Twitter to be used in new ways not envisioned by their creators by opening their data to developers through standardized interfaces. Overall, the key message is that opening data can fuel innovation and discovery at a relatively low cost.
