I'm trying to understand the addkeyword, when renaming my images I need to preserve the keywords, label and caption.
It works, but I endup with double keywords (if they are embedded in the file), and why the need of cataloging:createkeyword() if the keyword already exists in Lightroom.
So it seems that I need to create a function to compare the old keywords versus the renamed file.
--------- Get current metadata ---------
keywordTags = photo:getFormattedMetadata("keywordTags")
label = photo:getFormattedMetadata("label")
caption = photo:getFormattedMetadata("caption")
--- Set metadata back ----
photo:addKeyword(keywordTags )
gives an error -> assertion failed!
So first
cataloging:createkeyword()
photo:addKeyword(keywordTags )
