JS Obtain list of elements in library asset

I am trying to develop a script to obtain a list of elements in each library asset, and the link status of each.  The workaround has been to place each asset onto a page and then use the Links window to check the status of the elements.

This code returns [object Asset]:

var libList = app.libraries.item(0).assets.item(0).getElements();

This returns the name of the asset:

var libName = app.libraries.item(0).assets.item(0).name;

The eventual goal is to write a script for off-site disaster recovery.  It would relink each library asset element to a backup copy in the new location.

Is this possible without writing a script to  place each asset, update the links and then put it back in the library?

Thanks.

Hi,

Sure it is, however, it's basically consisting in placing library item, editing item, replacing ( or updating* ) item, removing placed content.

Quite time consuming but still quicker than manual operations.

I wrote a snippet that you need to set for your own needs :

function updateAllAssetsInLib ( lib )
{
          var libAssets = lib.assets.everyItem().getElements(), libAsset, placedAsset, doc = app.activeDocument;
  
          while ( libAsset = libAssets.pop() )
          {
                    placedAsset = libAsset.placeAsset ( doc );
                    placedAsset = placedAsset[0];
  
                    // do your stuff;
  
                    libAsset.remove();
                    lib.store ( placedAsset );
                    placedAsset.remove();
          }
}
updateAllAssetsInLib ( app.libraries.itemByName ( "foo.indl" ) );

Hope it helps,

Loic

*Pretty sure there is a "update library item" that you can call with meanuAction.invoke() but recently it disappeared from my UI to the point I started wondering if I had dreamed about it.

Thanks for the help.  I will enjoy stepping through this and watching the action.  In the meantime, I am wondering why the link status of an element can't be obtained via a property.  Apparently InDesign has to place the item before attemping to resolve the source.

Thanks again.

No I don't think you can check at link status while asset is in the library.
