Generally for open projects, the impact is hard to measure. It's not as simple as determining the sales. Overview of reuse and adoption by independent project is for me the most important measure. For example, for Wikipedia that Google shows it prominently on the search results, that students around the world frequently use it as first source to get an overview of a topic. For Wikidata this is not as established, but I would look at the collaborations. Other databases that have adopted the Wikidata Q-number is identifiers, for example, like we did in WikiPathways, and less domain-specific, by OpenStreetMap, if not mistaken. Those collaborations are a good indication of success: projects invest time in adoption of it, and would not do it if they did not expect "return on investment". >> I also note that public domain (which CCZero formalizes across >> jurisdictions) is still the "ideal" license when uploading images to >> Wikimedia, suggesting more of Wikimedia actually finds the CCZero idea very >> welcome. > > I'm not sure what you mean here.

My point was that the impression I get when uploading media is that the more liberal the license, the happier Wikimedia is about it. Egon -- E.L.
