I assume by „start the mapping“ you mean: creating example input and output files? The had designed design of these a while ago in the ITS IG but did not get very far. I put some questions in the ITS IG wiki see
https://www.w3.org/International/its/wiki/XLIFF_2.0_Mapping#Testing_the_mapping
once we have resolved them I’m happy to start with file creation.

Best,

Felix
