ebook-meta --series testme  t.pdf                                                                                                    
Original metadata::
	Title               : xxxaaa
	Title sort          : xxxaaa
	Author(s)           : R. Z. Bottema O. & Djordjevic
	Published           : 0101-01-01T00:00:00+00:00

Changed metadata::
	Title               : xxxaaa
	Title sort          : xxxaaa

Ok. I see you try with standard column.
Can you please reconfirm it works with custom column also?

Here my examples:

First (without changes)

Title : v3_demo-
Title sort : v3_demo-
Author(s) : Unbekannt
Book Producer : PScript5.dll Version 5.2.2
Published : 0101-01-01T00:00:00+00:00
Identifiers : crc32:52368
CRC32 : 52368
Mein Titel : old
Ja/Nein : Ja

Secound (with changes and "Embed metadata" button)

Title : v3_demo-
Title sort : v3_demo-
Author(s) : Unbekannt
Book Producer : PScript5.dll Version 5.2.2
Published : 0101-01-01T00:00:00+00:00
Identifiers : crc32:52368
CRC32 : 52368
Mein Titel : old
Ja/Nein : Ja

Third (with changes and "Interface Demo Plugin" button)

Title : v3_demo-
Title sort : v3_demo-
Author(s) : Unbekannt
Book Producer : PScript5.dll Version 5.2.2
Published : 0101-01-01T00:00:00+00:00
Identifiers : crc32:52368
CRC32 : 52368
Mein Titel : meta

All these results are with this Preferences (pic 001,002,003)

And to demonstrate setting of custom column metadata

ebook-meta --from-opf ~/test\ library/Kovid\ Goyal/DOCX\ Demo*/*.opf t.pdf                                                            *
Original metadata::

OK. I see you read the metadata from the opf and not direct from pdf. Right?

How look your solution from

ebook-meta file.pdf

One more thing i see is, with "Embed metadata" button i don't get a message, with "Interface Demo Plugin" button i get a message. See pics 008,009

[tribbleoo]

One more thing i see or find out
Its a different how the pdf was imported

If you Drag&Drop the PDF and you have follow Perferences, the functions from the Buttons looks equal
(Pic010)

If i Drag&Drop a PDF with Preferences like Pic003, the functions of the Buttons are different.

I am not shure is my fault or is a bug.

No --from-opf is used to SET the metadata. It is set in the pdf and then read from there

[tribbleoo]

thx again for spent your time. Maybe i really missunderstood the function.
But why, with the one Button it writes the changed data direct to PDF or i can see the changes direct after push the button and why with the other button i get a different response in my PDF (no data changes)? This is what i don't understand.
If the function is the same, i think i must get with both buttons the same solutions. Right?

You are doing something different in the two cases. Cant help you with that.
