[Solved] How to correctly set up XMP export?

Post by FataMorgana » Wed Feb 19, 2020 5:48 am

Hello,

I started using XnViewMP very recently. As a Linux user I normally use Geeqie, which is simpler than XnView, but has some (small) drawbacks.

I have 30k+ images in SVG and PNG format. The SVG files have their keyword metadata in xmp sidecars (created in Geeqie) and PNGs have their keywords embedded in the file itself (probably as xmp). My aim is to use XnView to rename these existing keywords/categories, while everything else needs to stays the same. They are non-hierarchical, but just simple single-level keywords. As I intend to use XnView in addition to other image managers, I am (for now) not interested in using the xnview database exclusively, but have the keywords (re)embedded in files (or sidecars).

In Settings>Metadata>IPTS&XMP I selected "Import xmp subject or iptc keyword to db categories" and all the keywords/categories got correctly imported - at least it looks so in the sidebar window (the one with "Folders", "Favorites" and "Categories Filter"). However, in the <DB result> view, keywords or categories are visible only for the PNGs, but not for the SVGs.

I am very confused about how to set up the export options. I assumed I needed to check "Export db category to xmp subject and iptc keyword" and then untick "Create iptc data". And also to check: "Update or create xmp sidecar". I would like the modified keywords to be written to the existing xmp sidecar (for the svg images) and updated in the embedded xmp data (for PNGs).

When I did that on a few images as a test, and checked the result in Geeqie, the keywords were lost, though they stayed correctly assigned within xnview. In xnview these test images have xmp AND IPTC info (while the other images, the ones I didn't manipulate, do not have IPTC).

I'd be very happy to receive some indication as to where to look for some instructions. Thank you very much.

I found the solution in a manual. It was not easy to find and I had to use Google Translate, but I found it very very helpful.

Here is the link (in French) in case anybody else is looking for concise explanation on metadata manipulation:
