[wdmmg-discuss] Infer Dataset Size

[Stefan Wehrmeyer]

Hello,

I'm working on the new homepage for OpenSpending and I want to put up a visualization similar to this: http://openspending.org/dataset/cra but I want to compare the size of the different datasets.

I understand that it is not straight-forward to determine the size of the dataset from the spending entries – or is it? 
I'm looking for something like total budget amount for a dataset, but that might not be the sum of the (non-aggregated) entries.

Do I manually need to enter a total amount for each dataset from some source or is there a feasible way to infer this number from the dataset's entries?

Cheers,
Stefan
