How do you mean?  There are several archive formats: binary, text,
xml.  See:

#include <boost/archive/binary_oarchive.hpp>
#include <boost/archive/binary_iarchive.hpp>
#include <boost/archive/text_oarchive.hpp>
#include <boost/archive/text_iarchive.hpp>
#include <boost/archive/xml_oarchive.hpp>
#include <boost/archive/xml_iarchive.hpp>

Or do you mean define different serialization methods for a class?
Such as:

class Foo {
   template<class Archive>
   void serialize(Archive& ar, const unsigned int version);

   template<class Archive>
   void serialize_II(Archive& ar, const unsigned int version);
};

Where serialize_II presumably reads and writes the data structure
in a different order?

Or do you mean something else?
