Open Data really is the Goose that Laid the Golden Egg! My favourite report on the subject so far http://www.force11.org/sites/default/files/attachments/EARSC-Study_GMES-Open-Data-Policy_Final-Report_Dec-2012.pdf.
A nice analogy and a good set of reasons why public sector created data should be made a available FREE for anyone.
Working on the “How” they do this on a European scale is the usual challenge, particularly with the wealth of different charging structures in each member state. But entrepreneurs will pick up quickly in the early “free” markets. We will show how free data improves the economy for all!
