Is the result of app.activeDocument.metadataPreferences an XMPMeta object?

[Guest]

Hello again

Hope this isn't too dumb a question.

I asked myself whether the result of

app.activeDocument.metadataPreferences;

is an XMPMeta object as per the "JavaScript Tools Guide".

I'd say yes, because I found examples where the previous statement is followed by

myDocXMP.setProperty(destNamespace, destNodeName, nodeValue);

But I'd also say no, because when I try

myDocXMP.deleteProperty(destNamespace, 'CreatorTool');

in ExtendScript Toolkit I get an error message saying "myDocXMP.deleteProperty is not a function".

The more I read, the more I get confused. Can you help me finding a source of information suitable for beginners? Thank you very much.

Hi,

metadatapreferences does not offer method deleteProperty()

Have a look: http://jongware.mit.edu/idcsjs5.5/pc_MetadataPreference.html

Those methods belong to lib:AdobeXMPScript.

It's not as easy to handle so. Did you try another tool as exiftool from commadline ...¿

Hi

Thank you very much, I read the page and bookmarked the whole resource. I also visited the ExifTool homepage.

Now I think I understand that metadataPreferences just happens to have a setProperty method but has nothing to do with XMPMeta objects that only exist in the context of the Adobe XMP Script library.

I apologize for having messed things up.
