As with open source software, open licensed data is all about being free. Free as in 'costs nothing' and...

32. Harry Wood's interest in internet collaboration and web2.0 technologies lead him to the OpenStreetMap project three years ago, as a hobbyist mappper, and as an increasingly passionate evangelist, community coordinator and developer. Turning this hobby into a profession, he worked at CloudMade developing core features of the OpenStreetMap website and working on CloudMade products and services which help developers use OpenStreetMap data. In 2010 he plans to operate as a freelance OpenStreetMap consultant http://harrywood.co.uk These slides are (of course) freely re-usable under the Creative Commons Attribution-ShareAlike 2.0 License Map images cc-by-sa2 OpenStreetMap.org contributors.
