org.apache.stanbol.entityhub.core.mapping.DefaultFieldMapperImpl
This is only an intermediate solution just to have the functionality. This needs to be refactored! This is something similar to a semantic lifting work flow that could used schema translation, reasoning ...
The goal is to build a simple Module that supports basics things (like the stuff provided by this implementation) and that allow other implementations to do the advanced stuff.
Currently I hope, that when the functionality is in place it is easier to see what a good design for this part of the Entityhub would be. TODO: refactoring (see above comment) @author Rupert Westenthaler
