Hi Filippo,

Information about embedding metadata in fo output which goes to the PDF is found here:

https://xmlgraphics.apache.org/fop/2.3/metadata.html

The data can be changed by customizing this template found in fo/fop1.xsl:

<xsl:template name="fop1-document-information">

Greetings,

I document my software using DocBook5 in a Debian GNU/Linux box. When the PDF files are generated, the CreationDate field gets filled-up using a new value at each run. This is a problem in our Debian effort to have "reproducible builds" [0] with the "forensic science" idea that the same code should produce the same
binaries bit-by-bit [1].

It seems that FOP is responsible for filling-in the CreationDate field.
Are you aware of a method to direct FOP in some manner to fill-in that
CreationDate with a constant value?

Thank you for your kind attention,

Sincerely,
Filippo
