It must be the XMP: Label, because without the Label-TAG it works without problems.

[Phil Harvey]

ExifTool should have no problem with an "xap" namespace if it has a proper URI associated with it.  Without seeing the raw XMP I can't tell you what the exact problem is.

- Phil

[cocteau]

sorry forget

[Phil Harvey]

Yes.  There is no "xmlns" definition for the "xap" namespace prefix.  So the XMP was not written correctly.

also works, only not with xap:Label... and  and "Label       => { },"is also defined in xmp.pm

can I declare it myself in the ". exifTool_config"?

[cocteau]

aaaahhhhhh, I found the bug:)
if, xap: Label="Approved" before xmlns: xap***, it does NOT work
but, xap: Label="Approved" AFTER xmlns: xap*** it works.

Order! is that soooo important?

[Phil Harvey]

Yes, the namespace must be defined before the tag may be used.

Hi guys,

I have the same issue with XMP generated by Photo Supreme. Hert (PSU developer) tell me - its a BUG by ExifTool not PSU, because ExifTool can read this data (but not modified) and because here https://www.w3.org/RDF/Validator/ is the XMP file declared as valid.

[Phil Harvey]

Ah.  Looking more closely at the XMP sample that was posted, I see that the "xap" namespace is actually defined, but after an attribute that already used that namespace.

Reading the XMP documentation, the order of the attributes doesn't matter, so in theory the xmlns attribute (ie. namespace definition) may come after an attribute that uses that namespace.  So this seems to be an ExifTool deficiency after all.  It is funny that this has never been a problem in the 14 years that ExifTool has been supporting XMP, so although the XMP produced by PSU is technically correct, it is very uncommon.  I have patched ExifTool 10.71 to be able to deal with this.

Thanks for following up on this.

- Phil

Edit:  Hert has sent me an email saying he will also change PSU to write the namespace first.

[RobiWan]

Hi Phil,

thank you very much - and because I forgot this - of course Happy New Year

I have patched ExifTool 10.71 to be able to deal with this.

Thank you so much.

Hi Phil,
I still have difficulty with updating a jpg file.
I receive 'Warning: Undefined XMP namespace: attr - C:/NG Pictures/NG_RenameThese/NG 2014-03-11 - Wave of Industry.jpg'.
I'm using version 10.87.

Code Select Expand


C:\>exiftool -ver
10.87

C:\>exiftool -overwrite_original -XMP-dc:Description="A lone surfer" "D:\Wave of Industry.jpg"
Warning: Undefined XMP namespace: attr - D:/Wave of Industry.jpg

    1 image files unchanged

C:\>exiftool -overwrite_original -XMP-attr:All= -XMP-dc:Description="A lone surfer" "D:\Wave of Industry.jpg"
    1 image files updated


If I remove the XMP-attr group, I can perform the update.
Is there some further information I can supply?

[Phil Harvey]

Can you send me the jpg so I can try this?  philharvey66 at gmail.com
