Documenting the spread of OECD norms: Country by Country Reporting Map

Here is a world map showing status of implementation of the OECD's Country by Country Reporting regime; clicking on the flags gives a brief country status report. I'm not really sure how informative it is in that it is not all that useful to read simply that CBCR is being implemented but the implementation date is "unknown" in various countries, especially when the little flag masks real controversy surrounding the country's intentions.  Also I am not sure what to make of all the blank space--do the map's curators think these other countries are irrelevant to the inquiry? Even so, if the idea is that the map will one day be covered in green flags, and that the world with green flags is remarkably different than today's world with mostly red and yellow ones, watching the map evolve will be a fascinating study in the power of soft law.
