IPTC - DateCreated and TimeCreated


Herb

Recommended Posts

Hello,

 

I am working with Daminion standalone version 1.0.0 build 779.

 

Today I modified the Creation Datetime of a *.jpg file and stored the metadata inside the image.

Then I have seen that the IPTC metadata DateCreated and TimeCreated are stored twice inside the image.

 

This happens in case of IPTC metadata is created by Daminion and also in case of IPTC metadata is only modified.

 

I think this is an error.

 

Best rgards

What do you mean by "DateCreated and TimeCreated are stored twice inside the image"? According to IPTC/NAA specification Created Date and Time fields are 2 separated fields and are stored separately (unlike the datetime fields in EXIF and XMP specifications).

 

You can disable writing tags into the IPTC from the program preferences: "Edit > Preferences > Writing Metadata > Add Compatibility with Windows Explorer and old programs".

Hello Murat,

 

thanks for your reply.

Yes you are right in IPTC exist 2 tags: DateCreated and TimeCreated.

 

As described in my MakerNotes post I added lots of date/time values, modified field "Creation DateTime" in properties window and wrote it back into the image.

 

Now both fields DateCreated and TimeCreated are contained twice inside the file.

Please see the attached image. It is the Daminion modified image of my MakerNotes post.

 

Best regards

Herb

If I import the image that is attached to the previous post, and invoke the "Item > Show All Metadata" command I see the following info in the IPTC:

 

---- IPTC ----
Coded Character Set              UTF8
Originating Program              Version 1.1
Date Created                     2013:04:01
Time Created                     17:38:18+02:00
Caption-Abstract                 OLYMPUS DIGITAL CAMERA
Urgency                          0 (reserved)

 

Could you please send me a screenshot where I can see that DateCreated and TimeCreated are contained twice inside the file.

Hello Murat,

 

using the following Exiftool command: exiftool.exe -a -g -all image.jpg

(please see also my post Usage of Exiftool)

shows the following output for IPTC data:

 

---- IPTC ----

Coded Character Set : UTF8

Date Created : 2013:04:01

Time Created : 17:38:18+02:00

Originating Program : Version 1.1

Date Created : 2013:04:01

Time Created : 17:38:18+02:00

Caption-Abstract : OLYMPUS DIGITAL CAMERA

Urgency : 0 (reserved)

 

 

On the other hand, if you open the image with a hex-editor you will see, that both tags

DateCreated (H'1C0237) and TimeCreated (H'1C023C) are stored twice.

 

Best regards

Herb
