In order to move on on other topics, here is a recap of DxO upcoming implementations (already mentionned above)
Then regarding the MWG recommendations mentionned, they are not all up to date and other software do not follow it. The recommendations are for flattering of “mwg-kw:Keywords” tag. We do not support it at all. There is nothing about flattering of “lr:HierarchicalSubject” in MWG recommendations.
Concerning the advanced metadata conflicts resolution, we are going to think about it and see whether or not we can propose something in a near future alongside the previous options mentionned.
We’ll close this topic in order to move on on other subjects.
