I wrote a utility script to put the data into a an sqlite database since that's easier for programs to work with. Would it make sense to contribute the script to the KanjiVG project, so that everyone who uses it has an extra option for how to access the data?
Currently it just makes a kanji table with character, variant, and svg columns and a component table with parent and child columns (since these are the things that would be useful for anki addons I'm considering writing.) I could make it include more if that would make it more generally useul.
