@JohanElzenga Said, "I think Adobe has decided not to do this, because no matter how you try to implement it, it won't work with hierarchical keywords on one end (Lightroom Classic) and flat keywords (Lightroom) on the other end. Using hierarchical keywords means you can have the same keyword in different hierarchies. Flat keywords means you cannot have two identical keywords, so synching these will create problems one way or another. Yes, this has been requested for many years, but the problem remains the same after all those years. This has nothing to do with being unwilling to give long-term, loyal, paying subscribers what they asked for" I agree that Adobe has decided not to do this, but I don't think it is correct that it can't be done. I've posted variations of one idea on how to do this several times, but here it is again for new readers...... PROPOSED WAY TO SYNC KEYWORDS BETWEEN LR/CLASSIC AND LR/CLOUD Even keeping the constraint that LR Classic uses hierarchical KW's and LR Cloud uses a linear (flat) KW structure, this problem can be solved. There are, of course, some technical aspects but the main rationale I've heard so far for not doing this is the logical problem of how to map a hierarchical structure to a linear structure. One solution is to convert LR Cloud to a hierarchical structure but putting that aside, here is one possible solution to that problem: 1) In LR Classic, Adobe can add check boxes in the create/edit keyword dialog for "Sync this KW with LR Cloud" "Sync Containing KW's with LR Cloud" "Sync Synonyms with LR Cloud (would become regular KW's in LR Cloud)” 2) . In LR Classic, whenever you mark a Keyword to Sync (as suggested above), it checks to assure that another keyword with the same name but under a different parent – or no parent - is not also marked to Sync. If it finds one it would deny the request with a message. For example if I am trying to sync KW “Red” under KW “Flowers” and it finds that I already synced KW “Red” under “Cars” the request would be rejected. In our example, if one wanted both occurrences of "red" to sync, the user would need to rename one or both of them (e.g. Red-Flower and Red-Car). 3) In addition, Parent keywords in LR/Classic can also sync into the flat LR/Cloud structure where using “Sync Containing Keywords” option uses the same logic that is used today with export. Of course those synced parent keywords would no longer be parents in LR/.Cloud but would also be in the flat structure. 4) If an image in LR Classic loses a keyword or these tick's get changed, the changes on effected images can sync to LR Cloud. This may include adding or removing KW’s in LR Cloud or attaching/detaching keywords from images in LR Cloud 5) If a user defined KW is added to an image in LR Cloud it could map to either no KW in LR Classic or at most one "ticked" KW in LR Classic. In the former case, LR Classic would create the new KW at the root level of the Hierarchy with "Sync this KW with LR Cloud" ticked. In the later case there could be only 1 ticked LR Classic Keyword (or synonym) with that name that would be affected. Of course there are plenty of corner cases and details that would need to be addressed, but I worked for Adobe for several years and have a very high regard for the quality of the engineers there to solve this problem if management would just ask them to do it. THIS CAN BE DONE if there is a will to do so and the more people who "vote" for having KW's sync between the ecosystems, the more it will push Adobe to re-consider this. .
