Accessing OriginalRawFileName through xmp?

[edvardkrupke]

Hi!

I am having trouble with accessing the XMP OriginalRawFileName - can anyone help me?

I need to be able to read what the original filename of a picture is, and figured this would be easiest to solve by looking at the xmp data, but I can't even read that properly - I am obviously doing something wrong.

SuperMerlin wrote this, and I tried just copy/pasting it - but I cannot get a result even from the unmodified original code;

#target photoshop;
if(documents.length){
if (ExternalObject.AdobeXMPScript == undefined) ExternalObject.AdobeXMPScript = new ExternalObject('lib:AdobeXMPScript');
var xmp = new XMPMeta(activeDocument.xmpMetadata.rawData); 
var shadow = xmp.getProperty(XMPConst.NS_CAMERA_RAW,"ParametricShadowSplit");
var exposureValue = xmp.getProperty(XMPConst.NS_CAMERA_RAW, "Exposure"); 
var keys = getArrayItems(XMPConst.NS_DC,'subject');
for(var a in keys){
    //amend the match for your keywod
    if(keys.toString().match(/key1/)){
        //things to do if keyword found
        alert("keyword found");
        break;
        }  
    }
};
function getArrayItems(ns, prop){
var arrItem=[];
var items = xmp.countArrayItems(ns, prop);
            for(var i = 1;i <= items;i++){
                    arrItem.push(xmp.getArrayItem(ns, prop, i));
                }
return arrItem;
};

 So - how would one modify the above (or write new code) to access the OriginalRawFileName?

Thank you in advance!

I'm guessing part of the answer may be:

(XMPConst.NS_CAMERA_RAW,"RawFileName")

However, I'm probably wrong.

Well it's at least logical - but I don't know how to use it yet:/

I just did a Batch Rename in Bridge with Preserve current filename checked. This is the tag and namespace. I'd look there.

xmlns:xmpMM="http://ns.adobe.com/xap/1.0/mm/"

<xmpMM:PreservedFileName>foo.CR2</xmpMM:PreservedFileName>

[Stephen Marsh]

RawFileName “naturally” exists in any file processed through ACR. PreservedFileName is obviously set by Bridge using the Batch Rename tool. What if a raw file has not been touched by either ACR or Bridge?

[edvardkrupke]

The images will probably get handled via Bridge, but since I am buildning a script to handle everything automatically, I'd like to have it as a stand-alone function:/

Is that you? Getting EXIF field "OriginalRawFileName"?

[edvardkrupke]

Yes!:) Great work you do over at PS-Scripts btw!

I modified a script by Dan Ebberts found here.

It detects raw filename on jpgs saved from a RAW, but you need to open them manually - I cannot get it to work on the current file (activeDocument) though - will try to solve it tomorrow if I have time to have a look on it then...

Here's what I've got right now;

try {
	var metaFile = File.openDialog("Select file to import.");
	var xmpFile = new XMPFile( metaFile.fsName,  XMPConst.FILE_UNKNOWN, XMPConst.OPEN_FOR_READ);
	var xmp = xmpFile.getXMP();
	var RAWFileName = xmp.getProperty(XMPConst.NS_CAMERA_RAW,"RawFileName");
	try {
			alert("Found Raw Filename:\n" + RAWFileName.toString());
		} 
	catch(error) {
			alert("No Raw Filename could be found.");
		}
	} catch(error) {
		alert("Something seems to have gone wrong.\n" + error);
	}

 Thank you Stephen_A_Marsh for finding (XMPConst.NS_CAMERA_RAW,"RawFileName") for me!

[Stephen Marsh]

It is right there in the raw metadata of any file processed through ACR…Then it is just a matter of matching the name space. Of course, more than that is required but it was a start.

Try this:

This is just brilliant. I guess I'll have to credit both you and SuperMerlin - thank you so much, it does exactly what I want!

[Stephen Marsh]

My pleasure, it is a great way for me to learn! Here is a variation to remove the filename extension:
