trying to update multiple tags with the same name

gcx · November 02, 2015, 12:40:34 PM

Hello people!

I'm very new to ExifTool, but I've already spent a few hours on a problem that I have, and I can't figure it out.

I have thousands of files that need to have some of their metadata updated, they're .psd files, to it's XMP metadata. Those files contain custom metadata, but many of the tags have the same name.
For instance, I've used ExifToop to retrieve a certain tag with the following command line:
exiftool(-k).exe -XMP-ns:LayerGroupsName -S -a -u -G1 -w! txt

I get this:
[XMP-ns] LayerGroupsName: [Surface]
[XMP-ns] LayerGroupsName: BaseColor
[XMP-ns] LayerGroupsName: Reflectance
[XMP-ns] LayerGroupsName: Roughness
[XMP-ns] LayerGroupsName: MetalMask
[XMP-ns] LayerGroupsName: Cavity
[XMP-ns] LayerGroupsName: Normal
[XMP-ns] LayerGroupsName: Work`

Now I'd like to update those tags, I've used this:
exiftool(-k).exe -XMP-ns:LayerGroupsName="something"

It does update, but only one of them:
[XMP-ns] LayerGroupsName: something

The other tags that were in XMP-ns are now in XMP-tmp0:
[XMP-tmp0] LayerGroupsName: [Surface]
[XMP-tmp0] LayerGroupsName: BaseColor
[XMP-tmp0] LayerGroupsName: Reflectance
[XMP-tmp0] LayerGroupsName: Roughness
[XMP-tmp0] LayerGroupsName: MetalMask
[XMP-tmp0] LayerGroupsName: Cavity
[XMP-tmp0] LayerGroupsName: Normal
[XMP-tmp0] LayerGroupsName: Work

How can I change ONE of those tags specifically, since they have the same name?
Is that an array of some sort? I have no idea how to edit it if it is.

BTW, I've had to make a custom config file, which is a total mess, so that may be the reason, but I have no idea what I must do. Here's the content of the config file:
#------------------------------------------------------------------------------
# File: example.config
#
# Description: Example user configuration file for Image::ExifTool
#
# Notes: This example file shows how to define your own shortcuts and
# add new EXIF, IPTC, XMP, PNG, MIE and Composite tags, as well
# as how to specify preferred lenses for the LensID tag, and
# define new file types and default ExifTool option values.
#
# Note that unknown tags may be extracted even if they aren't
# defined, but tags must be defined to be written. Also note
# that it is possible to override an existing tag definition
# with a user-defined tag.
#
# To activate this file, rename it to ".ExifTool_config" and
# place it in your home directory or the exiftool application
# directory. (On Windows and Mac systems this must be done via
# the command line since the GUI's don't allow filenames to begin
# with a dot. Use the "rename" command in Windows or "mv" on the
# Mac.) This causes ExifTool to automatically load the file when
# run. Your home directory is determined by the first defined of
# the following environment variables:
#
# 1. EXIFTOOL_HOME
# 2. HOME
# 3. HOMEDRIVE + HOMEPATH
# 4. (the current directory)
#
# Alternatively, the -config option of the exiftool application
# may be used to load a specific configuration file (note that
# this must be the first option on the command line):
#
# exiftool -config example.config ...
#
# This example file defines the following 16 new tags as well as
# a number of Shortcut and Composite tags:
#
# 1. EXIF:NewEXIFTag
# 2. GPS:GPSPitch
# 3. GPS:GPSRoll
# 4. IPTC:NewIPTCTag
# 5. XMP-xmp:NewXMPxmpTag
# 6. XMP-exif:GPSPitch
# 7. XMP-exif:GPSRoll
# 8. XMP-ns:NewXMPnsTag1
# 9. XMP-ns:NewXMPnsTag2
# 10. XMP-ns:NewXMPnsTag3
# 11. XMP-ns:NewXMPnsStruct
# 12. PNG:NewPngTag1
# 13. PNG:NewPngTag2
# 14. PNG:NewPngTag3
# 15. MIE-Meta:NewMieTag1
# 16. MIE-Test:NewMieTag2
#
# For detailed information on the definition of tag tables and
# tag information hashes, see lib/Image/ExifTool/README.

I don't really understand what is going on here.

Unless your XMP tag is a List-type tag (bag, alt or seq), or is inside a structure inside a list, then it should only occur once. But if it is a list, then reading FAQ 17 may help.

- Phil

gcx · November 02, 2015, 02:06:08 PM

Thanks for your answer!

Yes, it appears to be a bag container, that's what I'm guessing from looking at the File Info in Photoshop:
<ns:layerGroups>
<rdf:Bag>
<rdf:li rdf:parseType="Resource">
<xmpT:name>[Surface]</xmpT:name>

I've been through that FAQ point already, but in the case of a bag container, shouldn't the output be on one line, separated by commas?
The FAQ mentions lists, but I don't know what a bag is actually. Is it supposed to behave like a list?

I've tried something like this:
exiftool -keywords=one -keywords=two -keywords=three DIR

But it didn't work.

Phil Harvey · November 03, 2015, 07:31:11 AM

XMP has 3 types of lists (bag, alt and seq) that are all handled the same way as far as ExifTool is concerned.

But LayerGroups is a (bag) list of structures (hence the parsetype="Resource"). Reading and writing XMP structures is more complicated. Add the -struct option to read them as structures, and write them in this format. See this page for details about reading/writing structured XMP.

Also, your config file isn't defining the structure properly. If you attach the entire XMP I will generate a config file for you that will write the structure. (attach the output of "exiftool -xmp -b FILE > out.xmp".)

Wow, that's so nice of you!

This is the XMP that I got:

OK, attached is a config file that should do what you want. Add "-config LayerGroups.config" as the first option in your command to load this config file (from the current directory).

Edit: Fixed case of "layerGroups" tag ID

I've made some progress, but I'm afraid that I'm still not able to write it...

Using your config file as well as adding -struct to the command line, I get this:

QuoteLayerGroups: [{FileSuffix=S,Name=|[Surface],ProfileName=Surface,ProfileOverride=false,ResizeOps=|,2x platform3|,2x platform4,XmlRawData=<settings profileid="10">..<resizeOp platform="platform1" operation="none" />..<resizeOp platform="platform2" operation="none" />..<resizeOp platform="platform3" operation="scale" value="2" />..<resizeOp platform="platform4" operation="scale" value="2" />..<resizeOp platform="platform0" operation="none" />.</settings>.},{FileSuffix=C,Name=BaseColor,ProfileName=Base Color,ProfileOverride=false,ResizeOps=|,2x platform3|,2x platform4,XmlRawData=<settings profileid="5">..<resizeOp platform="platform1" operation="none" />..<resizeOp platform="platform2" operation="none" />..<resizeOp platform="platform3" operation="scale" value="2" />..<resizeOp platform="platform4" operation="scale" value="2" />..<resizeOp platform="platform0" operation="none" />.</settings>.},{Name=Reflectance},{Name=Roughness},{Name=MetalMask},{Name=Cavity},{FileSuffix=N,Name=Normal,ProfileName=Normal,ProfileOverride=false,ResizeOps=|,2x platform3|,2x platform4,XmlRawData=<settings profileid="6">..<resizeOp platform="platform1" operation="none" />..<resizeOp platform="platform2" operation="none" />..<resizeOp platform="platform3" operation="scale" value="2" />..<resizeOp platform="platform4" operation="scale" value="2" />..<resizeOp platform="platform0" operation="none" />.</settings>.},{Name=Work}]

I used what's between the brackets [] as the value to update for LayerGroup, so like this:
exiftool(-k) -yourconfigfile -XMP:LayerGroups=(what's between the brackets but with some changes) myfile.psd
I get this:

Quote1 output files created
Warning: [minor] Fixed incorrect tag ID case for XMP-ns:LayerGroups - myfile.psd
1 image files updated

But it didn't update properly. The new file is 12 KB smaller though, and the XMP inside of Photoshop is broken (things moved around and the data is not readable anymore in my custome photoshop tool).

The problem is in the quoting of the complex command-line argument. To avoid this problem, I would suggest:

1. exiftool -layergroups -struct -b SRCFILE > out.txt

2. exiftool -config LayerGroups.config "-layergroups<=out.txt" DSTFILE

Also, I have updated the config file attached to my previous post to fix the incorrect tag ID case.
