Can't set documentTitle to a blank string

I have a client that wants the documentTitle field to be blank for certain PDFs. If I go to File > File Info (in CS5.5) and delete the Document Title and export a PDF, everything is fine. However, if a Document Title is already set and I try to remove it with JavaScript, it doesn't work:

    doc.metadataPreferences.documentTitle = "";

where doc is my document object. If I set it to any other string it works. I tried setting it to a space:

    doc.metadataPreferences.documentTitle = " ";

but that doesn't work either. Any workarounds would be appreciated. Thank you very much.

Hey Rick,

Try setting property directly to XMP:

doc.metadataPreferences.setProperty("http://purl.org/dc/elements/1.1/", "title", "");

Hope that helps.

Hi Marijan,

This works great! Thank you very much for the quick response. But I have a question: what is the significance of the http://purl.org/dc/elements/1.1/ namespace? How did you know what to use for this? Thanks.

Let's say I did a lot of research about a year ago about XMP and it's structure

Take a look at "Raw Data" tab inside "File Info" to find namespaces.

For more info about my research, take a look here: http://tomaxxi.com/?s=XMP

Hope that helps.
