Bug 216273

Did you configure digikam to store metadata in the images?

yes with the assistant
and i also tested "write metadata in image" and "reread..."

addendum

this photo had already geotag

i did not use digikam to geotag this photo

now i understand well the pb

import a photo with gps data
view exif then gps data are there
view xmp then gps data are not there

use geolocator to modify coordinate
view xmp then gps data are there

digikam does not synchronize gps data between exif and xmp if importing a photo with exif gps data

i made this experiment
i copy in my image folder a photo from digikam 0.9.6
this photo contain exif data and iptc data
in particular

EXIF data :
>>> Photograph Information <<<

exif User Comment : Hommage à Paul Riquet

>>> Global Positioning System <<<

GPS Version ID : 0.0.2.2
GPS Longitude Reference : East
GPS Longitude : 1deg 49' 35.972"
GPS Latitude Reference : North
GPS Latitude : 43deg 21' 8.244"
GPS Altitude Reference : Above sea level
GPS Altitude : 0 m

IPTC data :
File name: img023.jpg (IPTC Records)

>>> IIM Application 2 <<<

Caption : Hommage à Paul Riquet
Country Name : France

open digikam
the photo is well in the album
click on it
select xmp
no data in xmp view, xmp window is empty

close digikam
open digikam
then
same thing


se the joined photo
img023.jpg

addendum : i already send a bug report about this pb about if i remember the 0.10.x digikam version. it's a pity because its a major pb for someone who want to switch to 1.0.0 digikam version if htere is no sunchronizing mechanism for imported photo from old digikam version

thanks

same pb

Please tell me if I understand this problem correct:

Your image has GPS information in Exif.
You copy this image into your digikam collection. You do not edit the image or GPS information in any way.
You expect GPS information to appear in XMP.

yes
for any imported photo
i expect all exif and iptc data to appear in xmp
as they appear for a photo when i modify it with digikam

gps is a particular pb inside this general pb

Philippe, 

Using current code from svn trunk (digiKam, kipi-plugisn and libkexiv2), XMP must include GPS information now. Can you confirm this ?

hélas i can't confirm this

today i installed mandriva 2010.1

i open digikam 1.3
then
i select a photo with exif and iptc data
then
xmp is desesperatly empty

no caption
no country name
no province name
no city
no location name
no gps data

Phillipe,

Just installed Mandriva 2010.1. Nothing is recompiled. I use all base packages (digiKam 1.3.0) => XMP is there.

Got XMP panel from right sidebar, and turn on full list of XMP tags using button on top of XMP view.

digiKAm 1.3.0 under Mandriva 2010.1. GPS info are in XMP tags

"turn on full list of XMP tags using
button on top of XMP view"

yes i did this

xmp is empty

as i said

digikam does not synchronize data between exif,iptc and xmp if importing(from 0.9.6) a photo
or perhaps it is synchronized but viewer has a pb ?

if in digikam setting/xmp viewer settings i select "all"
then
in "custom list" all parameters have "unavailable" value
and
"full list" is empty

Run Exiv2 command line tool from Mandriva 2010.1. Do you see XMP data with your image.

In digiKam XMP information come from Exiv2 as well...

Gilles Caulier

i run "exiv2 -pa 100_0323.jpg"
result : exif and iptc data and no xmp data

exiv2 V 0.19

Can you see the xmp contents with exiftool? Otherwise there simply is no xmp in the images.

i made an error
with exiv2 there is xmp data
with exiftool there is xmp data

but for the two ones
- some xmp-iptc data are missing

Content Location Name           : Parc mauresque
City                            : Arcachon

today i am astonished.

i open digikam and this time is see data in xmp viewer

it seems when you import a photo you must close digikam to synchronize xmp with exif and iptc ?

in xmp viewer there is no itpc part as exif

But you can see XMP. that the goal...

Exif can be backported in XMP as well, but this depand of the software used in background. digiKam do not synchronize Exif to XMP.

IPTC do not have Exif section.

You don't need to restart digiKam to see XMP. metadata viewer read these information directly from file. But this is not the case about image properties view where digiKam use datatabase info. In digiKam database we duplicates some XMP/Exif enties, but not all (the most important in fact to process search)

For me this entry is not valid for me. Assign GPS info with digiKam, and you will see GPS data to XMP view.

Gilles Caulier

Moreover you can try to use the "Reread metadata from files" commands.

Or the write commands.

i made an experiment

i go to another imported (from digikam 0.9.6) album
then
no data in xmp viewer
then
i close digikam
then
i open sagittarius (a software to manage xmp, it uses exiftools)
http://sagittarius.vokod.com/

then
i open an album
then
i close sagittarius
then
i open digikam
then
success in xmp viewer i see xmp data

now i know who synchronizes xmp from exif and itpc
