How to import XMP file to a PDF?

Unfortunately you cannot import a custom XMP file directly into a PDF. But there is a round about way that it can be done from a JavaScript toolbar button.

For example, for an all JavaScript solution you could write a script that loads the XMP file into an embedded file, using the "doc.importDataObject()" function, and then use the XMLData object to parse and insert the custom XMP into the document metadata. There is an example of using the XMLData object in the doc.metadata entry in the Acrobat JavaScript Reference.

Another approach that might be more suitable for you purpose is to use the Acrobat IAC interface to build a VB application that passes the custom XMP data into an Acrobat Folder Level Script that then parses and inserts the custom XMP into the document metadata.

You can find both the Acrobat JavaScript Reference and the IAC reference on this site:

Thanks Thom,

that's what I wanted to know.

Cheers,
Bonurbe.

We are also trying the same.

Can any one please give little info on XML parse ie parsing and insertion of XMP file.

Thanks

Look in the Acrobat 8 JavaScript API Reference at the "App.metadata" object. One of the examples provides a very large script for parsing the XMP metadata and adding new info into it.

Thomp Great Thanks for help.

Hi,

How import metadata(contains special characters) in acrobat batch processing using javascript. pls see below my code.

this.importDataObject("XMP_File", xmpFle);
var xmpFile = this.getDataObjectContents("XMP_File");
var xmp_contents = util.stringFromStream(xmpFile,"utf-8");
app.alert(xmp_contents);

using the above code the accent(special) characters are not getting inserted.

any one can help me.

thanks in advance

Hi,

var xmpFile = this.getDataObjectContents("XMP_File");
var xmp_contents = util.stringFromStream(xmpFile,"utf-8");
app.alert(xmp_contents);

using the above code the accent(special) characters are not getting inserted in acrobat metadata.

any one can help me.

thanks in advance

If you are using non-Latin characters, then you should be storing the data in the attached file as "utf-16".

Hi

I am using spanish characters, even if i use utf-16/utf-8, i am not able to insert accent characters in the pdf metadata.

pls help me

Wow, this is really interesting. I tried a test using your code, where the XML file that was Attached to the PDF contained all ANSI (8-bit) characters, with some acented characters. ANSI characters are also the first set of 256 characters in Unicode.

The "this.getDataObjectContents()" function faithfully returned all the characters in the file, no problems here. It's the "util.stringFromStream()" function that failed. It completely ignored any characters that were not strictly in the English Character set. Just for kicks I also tried the other character decodings and they all failed to convert the acented characters correctly. Which is interesting because since they are in ANSI they really don't need any conversion. JavaScript is Unicode based.

So the "util.stringFromStream()" fucntion is either buggy, broken, or just weak. This conclusion is further supported by my next experiment.

Next I converted the XML file into UTF-16. Note, I converted the data in the file to UTF-16. This worked, all the acented characters were maintianed in Acrobat when I used "stringFromStream" with the "utf-16" decoding. But it's not as clean as you would like. The "stringFromStream" function doesn't seem to recognize the standard UTF-16 byte ordering tag. So in order for it to work, the XML has to be Big Endian with no prefix for byte ordering.

There is another alternative for you. Write your own conversion routine for the ANSI (utf-8) characters, instead of using "util.stringFromStream". This is actually quite simple.

Hi Thom,

Still i am getting the same.

For e.g I try to insert below title into pdf metadata using javascript in batchprocessing, actually this title is present in one xmp file

Fibrosis quística en adultos: acuerdos inter e intraobservador para las escalas de puntuación de Brasfield y Chrispin-Norman en la radiografía de tórax y relación con datos clínicos y espirométricosafter using this sctipt

this.importDataObject("XMP_File", "/c/xmp/test.xmp");
var xmpFile = this.getDataObjectContents("XMP_File");
var xmp_contents = util.stringFromStream(xmpFile, "utf-8");
console.println(xmp_contents)


the title changed as below, all accent(special) characters(í , ó) are missing.

Thanks in advance for you help

I would suggest converting the "/c/xmp/test.xmp" file to UTF-16 characters. This can be done with any reasonably sophisticated XML tool, like XML Spy. You can download a free trial. Then, in your code, change "utf-8" to "utf-16" in the "util.stringFromStream()" function.

Could someone help me out on this - point out what I'm doing wrong? Why is it "undefined"?

What I'm trying to do is write a javascript that will import some "Additional Metadata." I created the metadata on the Additional Metadata page and then exported the file, and then tried to reimport manually and that works fine. Now I want a js action attached to a toolbar button that will do that for me. Since 7.0 is so much easier to use, I'm trying to get the script working in 7.0.

I can enter

this.importDataObject("XMP_File", "/C/Program Files/Adobe/Acrobat 7.0/Acrobat/JavaScripts

at the console and when I do I get a return of "true" but no metadata is imported.

===Update===
I never could get the code to work at the console. I did get it to work via custom button but while it would import the file, it did not update the metadata.

Custom button code that worked (Acrobat 7 Pro):
var SetMetaData = app.trustedFunction(function()
{
app.beginPriv();
this.importDataObject("cName", "/C/Program Files/Adobe/Acrobat 7.0/Acrobat/JavaScripts/GLC.xmp");
app.endPriv();
});

app.addToolButton({
cName: "applyMetaData",
cLabel: "GLC",
cEnable: "event.rc = (app.doc != null);",
cExec: "SetMetaData();"});

Your code (after the update) does nothing more than to import a new data object (in the form of a file attachment) to the file.
This by itself can not update the metadata of the file.
