Description Jaroslav.Tucek 2015-10-04 17:09:58 UTC

Previously, captions entered through the Captions/Tags side-panel got stored in XMP:Dublin Core:Description. This no longer seems to be the case (Subject and Title are still populated correctly in XMP though).

Reproducible: Always

Steps to Reproduce:
1. Set a description through the Captions/Tags side-panel
2a. Check the XMP tags through the Metadata side-panel
2b. Check the XMP tags through exiv2

Actual Results:  
exiv2 -p a Budapest_10.jpg | grep Xmp\.dc | cut -f1 -d" "
Xmp.dc.subject
Xmp.dc.title

Expected Results:  
exiv2 -p a Budapest_10.jpg | grep Xmp\.dc | cut -f1 -d" "
Xmp.dc.subject
Xmp.dc.title
Xmp.dc.description

Which version of libExiv2 and libKExiv2 have you installed? Look in the components-info dialog from digiKam.

Comment 2 caulier.gilles 2015-10-05 07:07:18 UTC

Do your Exiv2 support XMP metadata. It's optional...

Here, problem is not reproducible...

Comment 3 Jaroslav.Tucek 2015-10-05 19:56:15 UTC

Hello, I have XMP support:

Exiv2 supports XMP metadata: Yes
LibExiv2: 0.24
LibKExiv2: 2.4.0

I have now discovered that changing BOTH captions and the date on the description tab of the Captions/Tags side-panel updates Xmp.dc.description, while setting only the captions leaves the tag entry blank.

The problem is also not to reproduce here. Please start digiKam from the console and see if there are any messages.

Comment 5 Jaroslav.Tucek 2015-10-08 20:38:40 UTC

Changing the captions and clicking "Apply" does produce some error messages, but they look unrelated:

Comment 6 Maik Qualmann 2015-10-08 21:16:27 UTC

All clear, digiKam >= 4.10.0 supporting tags from ACDSee. To support the namespace of ACDSee, you need the following packages versions:

libexiv2 >= 0.2.5 or libkexiv2 >= 15.04.3

Comment 7 caulier.gilles 2015-10-09 05:33:36 UTC

Which metadata settings do you use exactly in digiKam control panel ?

Maik, sound like this file is now fixed with 5.0.0 and stable Exiv2 0.25.

Comment 10 Maik Qualmann 2016-03-07 17:25:19 UTC

Yes, this issue is fixed for digiKam-5.0.0 and Exiv2-0.25. I close this bug now.
