Description Stéphane Bidoul 2014-09-21 18:08:28 UTC

In Digikam, it is possible to hide previous versions of an image, so only the latest version is shown.

As far as I can tell this information is only stored in the database. Or at least, it is not possible to know, by looking at the metadata of the original only, that it should be hidden because there is a more recent version.

It would be useful to write the flag (informing the image is a hidden version) in the XMP metadata (and the XMP sidecar file).

The image history which contain already versioning information into XMP digiKam namespace. This is not enough ?

Exemple:

>>> digiKam schema <<<

CaptionsDateTimeStamps : 
ColorLabel : 0
ImageHistory : <?xml version="1.0"?> <history version="1"> <file uuid="6251a840d7847a86ab79fdf351fb6f38eee940ca139c4164fadfa0b829f48166" type="original"> <fileParams fileName="640_IMG_6906_Kapliczka_v1.JPG" filePath="/mnt/data2/photos/TESTS/" fileHash="eee940ca139c4164fadfa0b829f48166" fileSize="119049" creationDate="2013-11-28T16:07:25"/> </file> </history>

Hello,

I have seen the ImageHistory field, but I could not find in it the information that a specific version is hidden.

For instance, when you create a version from the original, v1 has the ImageHistory field, but the original does not, and there is no way to know that the original should be hidden.

version 1:
   ImageUniqueID : ad340046be0d63810f21bd2c03302ec7eee940ca139c4164fadfa0b829f48166
version 2:
   ImageHistory : <?xml version="1.0"?> <history version="1"> <file uuid="6251a840d7847a86ab79fdf351fb6f38eee940ca139c4164fadfa0b829f48166" type="original"> ...

This is how digikam determines versions.  Version 2 points back to the ID of version 1.  There's an option in settings to show or hide originals.
