Thanks! Using streambuffer or std::istringstream/std::ostringstream is indeed very convenient.
Has anyone thought about introducing default values in serialization ...
Sorry that I didn't make myself clear. I meant to reduce the archive size (not count the size). For example, in demo_gps.hpp, instead of ar & boost::serialization::make_nvp("hour", hour) one might want to use ar & boost::serialization::make_nvp("hour", hour, 11) so that if the hour is 11, it is not serialized in the archive. During deserialization, if the hour is missing in the archive, 11 will be the default value.
If you want more compact archives don't use xml. Use either text or portable_binary(or plain binary for homogenous platforms). Additionally you can use these with boost.iostreams compressed filters. The structure of your class heirarchy drives the output/input of archive data. They only optional aspect is to use the versioning facility. Jeff
