Just a copy/paste about another topic regarding this missing feature for a too long time now…
I dream of a strong cross compatibility regarding XMP file between apps that manage XMP/IPTC fields.
Stop using author, title and keywords in a proprietary .dop file that’s too messy and dangerous ! And please give us a window to read and edit all the XMP/IPTC fields fulfilled by another external app that are ghost data inside PL4 that we do not even know until we use an external app to read/edit them.
Do the same experience I did :
I full-filled XMP fields into On1 Photoraw 2021, It created a .xmp sidecar next to my raw file. Those fields are perfectly readable and editable with XnViewMP (free software…developed by only one guy just FYI !) .
If I open again my raw into DXO PL4, it displays only the keyword. Nothing for Author nor Copyright that do exist in the XMP in the right fields.
So now, if I full-fill Author and Copyright and add one more keywords though DXO PL4 none of them are written in the XMP sidecar file but into the DXO .dop file maybe to preserve the integrity of the XMP file !!
Once my raw processed into a JPEG file, I could see all my keywords into On1 or XnViewMP that came from one side the .xmp file and the other side the .dop file !!! And the Author and Copyright fields are not those from DXO but those previously created with ON1 that has been respected but forgetting the DXO fields in a strange way. Sorry but frankly speaking, What a mess !
I know that some of the DXO team prefere DXO PL4 to stay and concentrate in a one strong feature instead of offering too much but please integrate as soon as possible the metadatas management. It’s a basic feature for years in the competitors apps and an essential tool for photographers during the curling/editing process. We are not asking for a complicated catalog or search engine (not yet) but inviting us to manage metada with an external app just for this feature is just infair, time consuming and pricey. V5 is on the way, please the Team, dont’ miss our expectations !!
