Thank you this is very useful to know.
Of course a key thing that Open Knowledge are linked with is transparency and if this is not clearly evident in the decision making then it could undermine the whole process and diminish the credibility that any government gives the Index.
As with so many things the logic should be that with the evidence available others should be able to replicate the process and generate the same results. If this is not the case that would be worrying.
It would be particularly helpful, for example in the methodology page, if against each indicator an live example from a country which demonstrates the ideal result and how it was calculated - that is worked examples. And show how marks are deducted for issues with levels of openness.
At the moment colleagues in the major organisations who generate the data are confused as there seem to be moving goalposts which makes it harder to know where to target future improvements.
