A lot of the discussion on the potential of open data focuses on the economic potential, and the impact on transparency. Important things, but the benefits of it don’t accrue at the public sector body (PSB) that opens up the data. To make sure that a PSB keeps routinely publishing open data, having a direct benefit for the PSB itself is a great motivator.
Open data can be a policy instrument to help reach policy goals. At different levels of maturity examples are available, starting at improving (internal) efficiency by reducing transaction costs, through seeing how third party usage impacts own policy goals, and stimulating that usage, to the emergence of new services created by citizens/organisations and public sector bodies collaboratively that would not be possible otherwise.
