[RajneshD]

Hello,

I need to read and modify a Photoshop psd file's metadata fields such as: 

1. Description, 
2. Document Title and 
3. Keywords 

into Python. Could you point me to Resources/ Examples of how I can do this?

Thank You, in advance, for your help.

Use the bridge or Photoshop menu File>File Info. Adobe Scriptinf supporte Action Mabager vode in JavaScript and I beluevet there may be some extenstin that can use Python scripting. 

JavaScript 

xml = app.activeDocument.xmpMetadata.rawData;
logInfo( xml);  
  

function logInfo(Txt){
    try {	
       var file = new File(Folder.desktop + "/temp1.txt"); 
       file.open("w", "TEXT", "????"); 
       //alert(file.encoding);
       file.encoding = "UTF8";
       file.seek(0,2);   
       $.os.search(/windows/i)  != -1 ? file.lineFeed = 'windows'  : file.lineFeed = 'macintosh';
       file.writeln(Txt); 
       if (file.error) alert(file.error);
       file.close();
       file.execute(); 
    }
    catch(e) { alert(e + ': on line ' + e.line, 'Script Error', true); }
};   

You can access meta data objects like info with javascript code like this. that check Info instructions for garbage and add garbage to instruction if it not in instructions I do to to avoid a problem Adobe introduced in CC 2015.5

if (app.activeDocument.info.instructions.indexOf("Garbage") == -1 ) app.activeDocument.info.instructions = app.activeDocument.info.instructions + "Garbage";
