MySociety.org just launched a campaign to make bills available over the internet in a standardised format.
This could be very well applicable to other government data, e.g. the planning applications.
An that is also what private companies ask government to do, for example Google Transit with public sector data.
So, this described format could well be the stage 4 of the benchmarking model we are trying to discuss here.
