Two more remarks:
1. LilyPond already seems to use some parts of the BOOST library (which
is kind of the extended C++ STL). There should be no license issues.
2. Despite the fact that there is no "json" in its name it works with
json files very easily:
boost::property_tree::ptree pt;
boost::property_tree::read_json(ss, pt);
Cheers,
