How to get the original font version?

Thanks Harbs but I should be more precise. I want to compare the font version used actually in document against the original font version.

The info shown in find font about version is:

Version: 001.001 (Created with - 001.002)

Where InDesign store the original information about fonts? I know InDesign write the last font information used into XMP when saving. Is InDesign keep previous XMP somewhere so it can find the first time a font have been used and retreive the version?

It depend how I load my font. If my font is in folder "~/Applications/Adobe InDesign CS5.5/Fonts" or "~/Library/Fonts", Document.Fonts is equal to Application.fonts. If I put my font in "Document Fonts" folder beside my ID document, it is possible to have 2 fonts with the same name and different version between Document.fonts and Application.Fonts but after a test, what is in Application is just a list of availlable fonts to InDesign and Document.fonts is the actual loaded fonts.

When fonts are missing using Document.fonts, I can get the name but the version output strangely like:

Document Fonts:

Helvetica Rounded          Bold  Version 2.062;PS 2.000;hotconv 1.0.57;makeotf.lib2.0.21895

Brush Script          Medium  Version 2.062;PS 2.000;hotconv 1.0.57;makeotf.lib2.0.21895

Normaly when my fonts are active the result is:

Document Fonts:

Helvetica Rounded          Bold  001.001

Brush Script          Medium  001.001

I'm looking now to use Document.stories.item() to gather original font version...

After many tries with Document.stories.item() it seems I can get only the first font used in each stories. It looks also if fonts are missing I can get only the font name et not the version. Maybe I don't use the right object... I have trouble to understand the Data Browser of ExtendedScript toolkit. Now my result is with missing fonts:

Stories Fonts:

Brush Script          Medium  Can't find Version

Helvetica Rounded          Bold  Can't find Version

and with font loaded at application level:

Stories Fonts:

Brush Script          Medium  001.001

Helvetica Rounded          Bold  001.001

Here the script I use:

var myApplicationFonts = app.fonts;

var myDocument = app.documents.item(0);

var myDocumentFonts = myDocument.fonts;

var myFontNames = myApplicationFonts.everyItem().name;

var myDocumentFontNames = myDocument.fonts.everyItem().name;

var myDocumentFontVersion = myDocument.fonts.everyItem().version;

var mytFontVersion = myApplicationFonts.everyItem().version;

var myString = "\rApplication Fonts:\r";

for(var myCounter = 0;myCounter<myFontNames.length; myCounter++){

myString += myFontNames[myCounter] + "  " + mytFontVersion[myCounter] + "\r";

}

myString += "\rDocument Fonts:\r";

for(var myCounter = 0;myCounter<myDocumentFontNames.length; myCounter++){

myString += (myDocumentFontNames[myCounter]);

    try{

    myString += ("  " + myDocumentFontVersion[myCounter] + "\r");

    }

    catch(err)

    {

    myString += "  Can't find Version \r";

    }

}

myString += "\rStories Fonts:\r";

for(var myCounter = 0;myCounter<myDocument.stories.length; myCounter++){

myString += (myDocument.stories.item(myCounter).appliedFont.name);

    try{

    myString += ("  " + myDocument.stories.item(myCounter).appliedFont.version + "\r");

    }

    catch(err)

    {

    myString += "  Can't find Version \r";

    }

}

myString;

Any idea? It should have a way to get the original font version if InDesign can remember it...

Thanks Jongware, it looks really like it. Finally I will use the XMP of InDesign to have the last used font version instead of the original one.

var myDoc = app.activeDocument;

var myDocXMP = app.activeDocument.metadataPreferences;

var theEvalCount =  myDocXMP.countContainer ("http://ns.adobe.com/xap/1.0/t/pg/", "xmpTPg:Fonts")

var myCount = eval( theEvalCount );

var myInfo = new Array

myInfo.push(myDoc.name);

   try {

        var j = 0

            for ( j = 0; j < myCount; j++) {

            var fontVersionEvalString= "myDocXMP.getProperty(\"http://ns.adobe.com/xap/1.0/t/pg/\", \"xmpTPg:Fonts[" + [j+1] + "]/stFnt:versionString\")";

            var fontVersion = eval(fontVersionEvalString)

            myInfo.push( fontVersion);

            }

        }catch (e){

    }

myInfo;
