Peter Hoogendijk commented on TIKA-4444:
----------------------------------------
FYI: I found that "xmp-pdf:keywords" (from the XMP-pdf metadata) is reported by
Tika as "meta:keyword".
So now I can actually determine the original "dc:subject" by removing the
entries from the following tags reported by Tika:
* meta:keyword
* pdf:docinfo:keywords
* pdf:docinfo:subject
But it would be very nice to have access to the precise underlying data, this
feels a bit as a hack that might get broken in the future.

> The xmp metadata "dc:subject" tag contains the wrong data: it shows a list
> with the data from the following tags:
> * pdf:docinfo:subject (from the pdf metadata)
> * pdf:docinfo:keywords (from the pdf metadata)
> * pdf:keywords (from the xmp metadata)
> And it is missing the data from the following tags:
> * dc:subject (from the xmp metadata)
> When looking at the XML for my testfile (see attachments) the xmp metadata
> contains the correct "dc:subject" and "pdf:keywords" but:
> * Tika shows the wrong data in "dc:subject" (from the xmp metadata)
> * Tika does not show "pdf:keywords" (from the xmp metadata)
> * Tika does not show the actual "dc:subject" (from the xmp metadata)
> This has been tested with tika-server-standard-3.2.0.jar and
> tika-server-standard-3.2.2-20250624.143628-8.jar
