Considering a set of relatively infrequently changing facts about external world, publishing them as RDF can be a good choice. Developers can use it in whatever way they need, including loading it into SQLite—and it’s self-documenting, so they don’t need some extra information such as a spec to explain what everything means. It can link to external data for things beyond its scope that someone else already took care of. Other data can link to it, too—so it benefits open information exchange. (Yes, RDF has got a bit of a bad rap in some circles, but I don’t think it’s entirely justified… More importantly, RDF is incredibly boring, so publishing such a dataset is likely to gather much less attention than releasing a free public API, at least here.)
