I think this data would be helpful if we want to test MAWG implementations supporting DC and MPEG-7, i.e. map from both to MAWG and compare the results, or even compare the results in the MAWG results with the values you get from COPHIR.

I'm not sure why you want the store the data in MAWG format (not only because there is the format issue). By mapping to MAWG you use a certain implementation, and unless you hand check the results you can only use it to test that another implementation of MAWG behaves like yours, but that doesn't prove that both are correct.

Best regards,
Werner
