Inserting XMP metadata using the CLI on Debian

[marcolarosa]

I've tried inserting some XMP metadata into a wav file using the debian cli tools but it doesn't seem to work. The blob is something i found online:

<x:xmpmeta xmlns:x="adobe:ns:meta/" x:xmptk="Adobe XMP Core 4.0-c316 44.253921, Sun Oct 01 2006 17:14:39">
   <rdf:RDF xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#">
      <rdf:Description rdf:about=""
            xmlns:pdf="http://ns.adobe.com/pdf/1.3/">

... snip ....

         <xapMM:InstanceID>uuid:1a365cee-e070-4b52-8278-db5e46b20a4c</xapMM:InstanceID>
      </rdf:Description>
   </rdf:RDF>
</x:xmpmeta>

And the command I ran (and output) is (the XML snippet above is in a file called AA1-002-A.wav.XMP.xml):

$ bwfmetaedit --continue-errors --verbose  --in-XMP-xml AA1-002-A.wav
2021-04-15 01:20:01 AA1-002-A.wav: Is open
2021-04-15 01:20:01 AA1-002-A.wav: xmp, (empty) --> (XML data)
2021-04-15 01:20:01 AA1-002-A.wav: Is modified

When I try to spit it back out I get nothing back:

$ bwfmetaedit --continue-errors --verbose  --out-XMP-xml AA1-002-A.wav
2021-04-15 01:21:24 AA1-002-A.wav: Is open
2021-04-15 01:21:24 AA1-002-A.wav: Nothing to do

Yet the same snippet can be inserted and then exported using the MacOS GUI version.

Please help!

I think is related to #51
Currently the --out-XMP-xml option doesn't output the XMP content to screen but saves it in .XMP.xml

hi @g-maxime I'm not getting the .XMP.xml file. It seems odd to me when I try to insert the XMP data the output says xmp, (empty).

Almost like the data is not being read by the tool.

2021-04-15 01:20:01 AA1-002-A.wav: xmp, (empty) --> (XML data)

Anyway here's a log from a run just now:

1. ls to check file sizes
2. the run
3. ls to check file sizes

$ ls -l
total 536328
-rw-r--r-- 1 debian debian 549189460 Apr 15 01:20 AA1-002-A.wav
-rw-r--r-- 1 debian debian      2288 Apr 15 00:01 data.xml

$ cp data.xml AA1-002-A.wav.XMP.xml

$ bwfmetaedit --continue-errors --verbose  --in-XMP-xml AA1-002-A.wav
2021-04-15 08:46:14 AA1-002-A.wav: Is open
2021-04-15 08:46:14 AA1-002-A.wav: xmp, (empty) --> (XML data)

$ ls -l

-rw-r--r-- 1 debian debian      2288 Apr 15 08:46 AA1-002-A.wav.XMP.xml
-rw-r--r-- 1 debian debian      2288 Apr 15 00:01 data.xml

Note file size of 549189460 for AA1-002-A.wav before and after. It should be different shouldn't it?

Also, here's a screenshot of the GUI tool on macos with that file after the insert - no XMP data.

However - the remove command is not working:

bwfmetaedit ... --in-aXML-remove ...
`bwfmetaedit ... --out-XMP-xml ...``

--> No the same xml field.

Tested with --in-XMP-remove, working for me.
