The document discusses Open Addresses, an initiative to create an open database of addresses in the UK. Open Addresses aims to make address data available for anyone to use for free by gathering data from open datasets and crowdsourcing. It is owned by the not-for-profit Open Data Institute. The benefits mentioned include increased social and economic value, faster publication of new addresses, and new businesses and services created through linked address data. Open Addresses plans to grow its user base through trial programs, social media, and mainstream media to publicize the initiative.
