[GOAL] OASPA CC-BY chart: where's the data?

[Heather Morrison]

OASPA has posted a picture of a chart of CC-BY growth on their blog:
http://oaspa.org/growth-in-use-of-the-cc-by-license-2/

The chart by itself is difficult to interpret. For example, to what extent is CC-BY growth conflated with OASPA membership growth or overall open access growth? 

Will OASPA be releasing the data for all to mine?

best,
