XMP Toolkit and Creator tags

[alex.v]

Hello.

I have been using Exiftool for quite long time. However, one month ago when I last used it, it was automatically writing

XMPToolkit                      : Image::ExifTool 12.64
Creator                           : JohnSmith

Now when I copy tags or create a new file I don't see these tags being added. How exactly can I check if they were automatically created and if they were not created why is it so? I didn't update my Exiftool so it seems really strange.

XMPToolkit is updated if you write any XMP tags.  This is common practice for all XMP writers.

Creator is never written automatically -- you would have had to specifically write that tag.

If you are copying tags, XMPToolkit will be written if you copy any XMP tags.

How can I know if its updated? Only using read feature?

By "it", do you mean XMPToolkit?  Use the -v2 option in your write command to see exactly what is written.  XMPToolkit will be written if any XMP is written.

Because I checked it online and using exiftool read feature and I don't see as if it would be updated.

Online?  Other software won't show XMPToolkit.  ExifTool will though.

I simply dont see any XMP Toolkit value in metadata. There is no such name and value.

All XMP writers write this information, but only ExifTool treats it as a tag.  You can set it to whatever you want with ExifTool.  See the XMP x Tags documentation for details.

I used to see it when I had changed anything before

This hasn't changed.  You must have changed the way that you "see" it.  It would be helpful if you were more specific.
