Reply To: Modifying raw data contained in File Info: Is it possible?

Some further thoughts. A couple of threads over on Adobe’s InDesign forum offers some tips. “XMP
: Remove a nod from InDesign metadata” includes a useful snippet of Javascript. Also a comment to “Edit
IDML, remove metadata, save, again open in InDesign – can’t open” shows that going through IDML is unnecessary, and includes a longer snippet.
There used to be a complete Javascript for zapping a whole section of XMP metadata: around 2013 Hans-Gerd Claßen posted a complete script for deleting the contents of xmpMM:History, but my link to the forum no longer works (Adobe lists contributions under his username <-hans-> back to 2014).
