The OSS in Big Cities initiative aims to promote open source software adoption among major cities. It will share success stories and best practices of cities using open source applications for e-government services, smart cities, and other domains. The initiative is led by OW2 and the City of Paris and hopes to engage other large cities. Activities will include networking events, writing documentation, and code/expertise sharing to build strategic awareness and support for open source among city IT leaders and officials. The goal is to help open source solutions gain equal consideration with proprietary options for cities' complex technology needs.
