XAP Identifier

[janice]

Hi,

I have a problem with generating xmp values. I need to add two xap Identifier tag. I'm using this command:
C:\temp\exiftool.exe -L -xmp-Microsoft:DateAcquired="2015-09-07T08:27:02" -xmp-dc:title="Title1" -xmp-dc:source="Title2" -xmp-dc:relation="original.jp2" -xmp-xap:Identifier="test1" -xmp-xap:Identifier="test2" "C:\temp\original.jp2"

I get an error:
Tag 'xmp-xap:Identifier' does not exist

So I tried with this command (without xap namespace):
C:\temp\exiftool.exe -L -xmp-Microsoft:DateAcquired="2015-09-07T08:27:02" -xmp-dc:title="Title1" -xmp-dc:source="Title2" -xmp-dc:relation="original.jp2" -xmp:Identifier="test1" -xmp:Identifier="test2" "C:\temp\original.jp2"

I this case it writes only one value for dc:identifier value "test2" and it ignores value "test1". I'm aware that old "xap", etc., prefixes are translated to "xmp". But is there a way I can get this working?

Regards,
Janice

Looking at the XMP tags, it appears that there are two types of Identifier tags.  Identifier appears to default to XMP-dc:Identifier which is a simple string tag, but the tag you seem to want is XMP-xmp:Identifier, which is a list type tag.

So try -XMP-xmp:Identifier="test1" -XMP-xmp:Identifier="test2".  That seems to work here, though if there is already an XMP-dc:Identifier tag, that will take precedent unless you add -a when you view the results.
