Aggregate web pages licensed

License statistics has basic information about linkback/page/search-engine-query-based license adoption statistics.

See the 'stats' module in our sourceforge repository for code used to gather these statistics.

Site-specific metrics

Content curators lists licensed works counts for many sites that collect CC-licensed works, e.g., about 40 million at Flickr.

Eventually code above should be expanded to collect this and finer-grained information (e.g., per site license breakdown) from these sites.

Other quantitative metrics

• creativecommons.org traffic: Alexa, Complete
• Number of journals, publishers (e.g., PLoS)
• Feature films that have been released in theaters.
• Universities?
• Press agencies?

Qualitative metrics
