Recently asked about CC use for works in Arabic. There are no Arabic-language jurisdiction ports available at this time; measuring adoption of jurisdiction ports is the easiest way to characterize patterns of adoption, as has been done by Giorgos Cheliotis, with interesting results -- also see http://monitor.creativecommons.org.

Fortunately there is some other data available that could be used to characterize CC use, irrespective of porting, across some languages and countries. This data is described at http://wiki.creativecommons.org/Metrics/Data_Catalog#License_property_search_engine_API_queries and available from http://labs.creativecommons.org/metrics/sql-dumps/all.sql.gz
(warning, approximately 200 megabytes).

Nobody has analyzed this part of the available data on CC adoption yet to my knowledge. Anyone is of course welcome and encouraged to!
