I'm dimly aware that there are differences in legal treatment of data collections (e.g. a telephone book, or map data like OpenStreetMap) as compared to, say, a novel or a program. For works like novels (and to some extent collections like Wikipedia and SE contents) the Creative Commons licenses are a good fit. For programs there is a plethora of open source/free software licenses. But I know of next to no similarly open licenses for data sets, except for the Open Data Commons Open Database License ODbl.
Could anybody share their insights, and perhaps point to some "choose your license" summary?
