Write keywords to XMP

Hi everybody,
I tripped over some strange metadata issue in the new DxO PL3 metadata editor (I am using Win 10 where this feature was rolled out recently) and I found this interesting thread in DxO forum.
In essence, the new feature is useless for me.
Here’s what I found out:

  • Opened a jpg with existing metadata (no sidecar file, embedded metadata)
  • Added Keywords in Photolab 3
  • Exported the image from PL3
    Now I checked the exported file:
  • in Adobe lightroom the newly added keyword appeared correctly in the keywords box, no problem,
    BUT
    opening the file from other image viewers (like freeware IrfanView or Pciture Information Extractor) didn’t show the metadata attribute that I was adding in DxO.

After some looking into the metadata in exiftool I found the following:

  • DxO correctly writes metadata into XMP, segment dx, into field “Subject”
  • DxO also correctly writes into the IPTC part, into field “Hierarchical Subject”
  • But DxO does NOT write the new tags into the IPTC part, field “Keywords”.
    I know, IPTC is pretty old, but still quite a lot of picture viewing programs do show IPTC keyword data, reading from this exact attribute. Lightroom, for example, correctly populates this field upon writing metadata into a file,
    I have issued a Ticket towards DxO, but support gave me the answer that it would “work as designed”.
    So if DxO considers this to be working correctly, the whole feature is useless for me, since I will not be able to see metadata maintained in DxO and I need to stick to my old DAM workflow.

Anybody else having a similar issue? If I am the only one, then possibly there is not the need to corrrect the existing Photolab 3 way of writing metadata :slightly_smiling_face:
