What does "adding" mean in verbose output?

[Elliott B]

Hello.  I have two OpenEXR files with similar metadata but they do not behave the same in Davinci Resolve.  I'm interested in the tag called 'Owner'.  Using exiftool -v5 I see that in one file, there is an additional line that says adding.  What does this line mean?

File 1:

Code Select Expand


  Owner = hub@c3049b4
  - Tag 'owner' (11 bytes, string):
      0849: 68 75 62 40 63 33 30 34 39 62 34                [hub@c3049b4]

File 2:

Code Select Expand


  [adding Owner]
  Owner = M001_C050_01085B
  - Tag 'Owner' (16 bytes, string):
      0929: 4d 30 30 31 5f 43 30 35 30 5f 30 31 30 38 35 42 [M001_C050_01085B]


With File 1, Resolve populates the reel name field using the Owner tag, but with File 2 it doesn't.

I solved the problem by using owner (lowercase) instead of Owner, and now it does not show this adding line.  But I'd still like to know what this means.

The "adding" means that ExifTool is adding an unknown tag to its internal list of tags.  You will see this message for any tag that isn't already known to ExifTool.  If you saw this message for a standard tag then there was something wrong with the way the XMP was written (either an incorrect URI, or as it seems in your situation the wrong tag ID).
