Comment:

 The whole point of the polymorphic archive is to permit usage of a common
 interface without depending on the specific one.  So really one is
 expected to use the base class "accessors"

 try the following:

 {{{

 // Create the target archive object, as input
 boost::archive::polymorphic_iarchive &targetData =
     boost::archive::polymorphic_binary_iarchive targetData(
         std::ifstream(sourcePath.external_directory_string().c_str())
     );

 // If the versioning implies that an update is not required
 if(targetData.get_library_version() == mTypeVersions[GetType?(asset)]) {

 // Load from the target // ...

 }


 }}}


 If that fails let me know.
