Metadata not visible in photoshop but it is with exiftool extraction

[itsjustvenky]

Hi, I have injected metadata into this PNG file, for example

<dc:description>
   <rdf:Alt>
    <rdf:li xml:lang='x-default'>Venkat-01</rdf:li>
   </rdf:Alt>
</dc:description>

So I used exiftool to extract metadata to verify the injection and the metadata is there, but when I check in photoshop cs6 (win x64), its not there.

Why this is happening ?? or there is something I didn't understood about metadata. please let me know

Thank you

The command I have used

exiftool -tagsfromfile Screen_Shot_2017-02-20_at_6.22.33_PM (5)_f3fec789-45e1-4e9d-b7e0-e01682d078ed.png output.xmp

Your command actually put the tags from the png into the output.xmp file, not the other way round. So if you switch them I think you find it will have worked.

Hi Hayo Baan,

I have already injected data into PNG (command is not mentioned here).
The command which I mentioned is used to extract the metadata from PNG into XMP so that I can see verify the metadata is injected or not.
So the question here is, why PS is not able to show the data in the "File Info" menu option, where exiftool could able to show when extracted to XMP packet.

Adobe Bridge sees the info in your file.  It may just be photoshop.

This very old thread (2009) says that PS doesn't support reading XMP data in a PNG.

This exiv2 thread seems to be similar and has a post from Phil.  It seems to indicate that pre-CC versions of PS do not support XMP data in PNGs.
