[Bug 310067] New: Optional finegrained metadata for Modified/Access/Changed time and Digikam Last Read/Write

[julien.t43+kde]

https://bugs.kde.org/show_bug.cgi?id=310067

            Bug ID: 310067
          Severity: wishlist
           Version: 2.8.0
          Priority: NOR
          Assignee: [hidden email]
           Summary: Optional finegrained metadata for
                    Modified/Access/Changed time and Digikam Last
                    Read/Write
    Classification: Unclassified
                OS: Linux
          Reporter: [hidden email]
          Hardware: Other
            Status: UNCONFIRMED
         Component: Metadata
           Product: digikam

From a quick test, it seems digikam is not making use of XMP tags MetadataDate
or ModifyDate
http://www.exiv2.org/tags-xmp-xmp.html
Lightroom seems to use them:
http://feedback.photoshop.com/photoshop_family/topics/xmp_metadatadate_has_wrong_time_zone
https://discussions.apple.com/thread/3329631?start=0&tstart=0
not sure about Aperture.

It would be nice to have an optional settings to fill more detailed time of
metadata edit based on MAC model (http://en.wikipedia.org/wiki/MAC_times)
A Digikam LastRead/LastWrite would also useful to help in Bug 227814 - "Write
metadata immediately" option to identify which files had been changed

Of course, those meta should be searchable (fixed field or more flexible google
search)



Reproducible: Always

Not sure when this changed, but digikam 4.8.0 makes use of all the available
Date fields.

Here is the results from a new blank file passed through digikam:

Exif.Image.DateTime                          Ascii      20  2015:03:06 16:26:47
Exif.Photo.DateTimeOriginal                  Ascii      20  2015:03:06 16:26:47
Exif.Image.PreviewDateTime                   Ascii      20  2015:03:06 16:26:47
Iptc.Application2.DateCreated                Date        8  2015-03-06
Xmp.xmp.CreateDate                           XmpText    19  2015-03-06T16:26:47
Xmp.xmp.MetadataDate                         XmpText    19  2015-03-06T16:26:47
Xmp.xmp.ModifyDate                           XmpText    19  2015-03-06T16:26:47
Xmp.digiKam.CaptionsDateTimeStamps           LangAlt     1  lang="x-default"
Xmp.tiff.DateTime                            XmpText    19  2015-03-06T16:26:47
Xmp.exif.DateTimeOriginal                    XmpText    19  2015:03:06 16:26:47
Xmp.photoshop.DateCreated                    XmpText    19  2015-03-06T16:26:47

It looks to me like digikam is now using MWG guidelines.

This file is not fixed with current implementation of MetadataHub. The time
stamp must be managed as Comment/Ratings/Tags information in Metadata Settings
panel.
