During Smart City Expo in Barcelona (we wrote about it here) another Polish city – Poznań – joined the initiative of the Open & Agile Smart Cities. OASC is a city-driven, non-profit organisation. The overall objective is to create a Smart City market. OASC was founded in January 2015 and came to life with the first wave of cities joining in March 2015. OASC continues to grow.OASC kickstarts the use of a shared set of methods to develop systems and make them interoperable across a single city as well as between multiple cities. Today’s smart cities are pioneering solutions that improve local practices while promoting sustainable job creation. OASC provides the network for cities all over the world to share best practices, compare results, and avoid vendor (and city) lock-in while advocating for de facto standards.
