Question to JSON

[herb]

Hello Phil,

I am working with Exiftool V11.02 on a Windows 7 system.
As testfile I used the file attached to DarwinCore at your internet side because it contains XMP tags and also structures.

(1) I created a *.json file with

Code Select Expand

exiftool.exe -json -all:all -w test.json test.jpg
and Exiftool created an outputfile with name testtest.json. I think this is an error.

This file could be re-imported using

Code Select Expand

exiftool -json=testtest.json test.jpg

(2) But when I try also to use options -g0:1 and -struct I see the following

Code Select Expand

exiftool.exe -a -g0:1 -struct -json -all:all -w test1.json test.jpg
created an output file with name testtest1.json
and for re-import with

Code Select Expand

exiftool -v -json=testtest1.json test.jpg

I get the following output on stdout:

Code Select Expand

Reading JSON file testtest1.json
======== test.jpg
Setting new values from JSON database
Nothing changed in test.jpg
and on stderr:

Code Select Expand

Now it is unclear to me what I am doing wrong.

Thanks for your help in advance

and Exiftool created an outputfile with name testtest.json. I think this is an error.

    -w[+|!] EXT or FMT (-textOut)
            Write console output to files with names ending in EXT

(2) But when I try also to use options -g0:1 and -struct I see the following

Code Select Expand

exiftool.exe -a -g0:1 -struct -json -all:all -w test1.json test.jpg
created an output file with name testtest1.json
and for re-import with

Code Select Expand

exiftool -v -json=testtest1.json test.jpg

            The imported
            JSON file must have the same format as the exported JSON files
            with the exception that the -g option is not compatible with the
            import file format (use -G instead).
