This document summarizes Jen van der Meer's presentation on open data. It discusses how open data is not just for governments but also has benefits for businesses through new products, services and economic value. Examples are given of open data fueling demand, such as flu tracking and Yelp reviews. While closed data limits sharing and scientific progress, open data has positive externalities by benefiting others. The presentation calls for more public-private partnerships and startups to advance open data and interconnect information for social good.
