-----------------------------------------------------------------
Thanks again! I've tested snapshots 12 and 18, but I'm still missing the
"dc:keywords" tag.
To be able to determine the original "dc:subject" tag, I need the
"pdf:docinfo:keywords", "pdf:docinfo:subject" and "dc:keywords" tags.
Our customer requires separate subjects and keywords, where:
* subject = "dc:subject", or "pdf:docinfo:subject" if "dc:subject" is not
present
* keywords = merged "pdf:docinfo:keywords" and "dc:keywords"
For now I'm using PyPDF to get the original "dc:subject" tag, but I prefer to
use only Tika as it also supports other file types (including embedded files).
I'm using the attached PDF file for testing: it contains unique values for all
the tags we need.

> Environment: * Docker container based on python:3-slim
> * Debian 12.11
> * Python 3.13.5
> * openjdk 17.0.15 2025-04-15

>
> Attachments: lorem-ipsum.pdf, lorem-ipsum.xml

>
> 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
