I need to provide a way for the customers to know the PDF revision numbers or date. I need to have the revision value or timestamp or anything similar at the footnote of the PDF. I tried adding tags in the bookmeta, but they are not picked during the build. Can someone help?
If you would use for publishing DITA to PDF Oxygen's specific "DITA Map PDF - based on HTML5 & CSS" transformation scenario which uses CSS for customizing the PDF output, you can use CSS pagination techniques: https://www.oxygenxml.com/doc/versions/24.1/ug-editor/topics/dcpp_headers_and_footers.html#ariaid-title7
If the DITA Map looks like this:
<map>
<title>Growing Flowers</title>
<topicmeta>
<critdates>
<revised modified="2022-06-03"/>
</critdates>
define for example a stringset with a certain name and use the stringset in the header for example:
*[class ~= "topic/revised"] {
string-set: hdrstr attr(modified);
}
@page {
@top-left-corner {
content: string(hdrstr);
}
}
