[digikam] [Bug 339273] New: Write "hidden file" version information in metadata

[sbi]

https://bugs.kde.org/show_bug.cgi?id=339273

            Bug ID: 339273
           Summary: Write "hidden file" version information in metadata
           Product: digikam
           Version: 4.3.0
          Platform: Other
                OS: Linux
            Status: UNCONFIRMED
          Severity: wishlist
          Priority: NOR
         Component: Versioning
          Assignee: [hidden email]
          Reporter: [hidden email]

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 <<<

CaptionsAuthorNames :
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>
ImageUniqueID :

PickLabel : 1

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.
