meta_system returns a list with the object's system metadata.
It is literally a wrapper to meta(x, field, type = "system")().
meta_system<- returns the object with the system metadata
modified. This is an internal function and not designed for users!
meta_system_defaults returns a list of default system
values, with the user setting the "source" value. This should be used
to set initial system meta information.
