My question, why is the following script not running within the "Additional Metadata"? Entries in the document properties, e.g. Title, author, etc. work with it.

The script:

function CopyrightStatusSetzen(){

var EingabemdCopyrightStatus = app.response({

cQuestion: "Geben Sie die CopyrightStatus ein:",

cCopyrightStatus: "CopyrightStatus eingeben",

cDefault: "1975"});

if(EingabemdCopyrightStatus == null){

}

else

this.info.CopyrightStatus = EingabemdCopyrightStatus;

this.layout = "MultiplePage";

// this.layout = "SinglePage";

}

app.addToolButton({

cName: "SetCopyrightStatus",

cLabel: "CopyrightStatus setzen",

cTooltext: "CopyrightStatus setzen",

cEnable: true,

cExec: "CopyrightStatusSetzen()"});

could someone help me?

System: Windows 7; Acrobat DC

Thank you and best regards

Doc.info sets fields in the Info dictionary, as documented. Additional metadata is not stored there, or displayed. You can set extra fields in the Info dictionary but it won’t be merged into metadata. Standard names are automatically merged into the XML metadata, which you can read and write as a packet using Doc.metadata.

Thank you for your answer, but what does that mean? Is it not possible to insert data in the "additional metadata"?

Thanks

That's not true. If you set a custom property under this.info it is saved and is displayed later on, under File - Properties - Custom.

For example, I've ran this code:

this.info.CopyrightStatus = "RESERVED";

Then saved and closed the file, then re-opened it, and this appears:

It's also a part of the file's raw metadata XML:

It means your code cannot work, and to update additional metadata requires a lot of study and development.

I recommend studying the PDF Specification, ISO 32000-1, to understand the different types of metadata. This may lead into study of XML in general and XFA metadata. Then you would need to update the XML metadata somehow.

So I do not say it is impossible. But you may not have the time or resources to do it.

Hi try67,

yes that's right, but I need the entries in the Description tab (Additional metadata), and that does not seem to be that easy or impossible?

Love from

Ah no, there you can only use the built-in properties, not ones that you've added yourself.

Actually, that's not quite true... If you go to Properties - Description - Additional Metadata - Advanced and expand the last item in the list, you'll see your custom properties:

You should notice that the data is in the XML format and that is what needs to be edited. This property was added in Acrobat 7.0 and one needs to use the XMLData object and the XMLData.parse method.

This is not a beginner's project.

In order to do it you will need to edit the XML code of the metadata property.

My suggestion is to print out this string before applying these properties, and then after, and comparing them. That will give you an indication of what you need to change in order to achieve it. As mentioned, this is not a simple project.

What app is that? Looks like it may be a separate general XMP viewer. If so, it won't be looking at PDF/X metadata...
