 ### How could we configure our mapping for serialization?
 
-We can have as much mapping definitions for a class as we need. An easy way to start to define our customized maps is exporting the default MAP0 and importing it again with a different name, then we can make changes in the map regarding the properties that should be exported /imported, names, conversor methods to apply. To do this, we can modify directly in the global, or do it programatically (See `OPNLib.Serialize.Util` class for tools to export/import maps, get / set property mappings,etc…)
