Can you import metadata from an excel database to images (JPG, PSD, TIF) in bulk?

[PennyStamp_heypen]

I am very new to working with metadata. I have a microsoft excel file with the IPTC Core fields I need for each image file.

(Creator, Headline, Description, Keywords, Title, Job Identifier, Credit Line, Source, Rights Usage Terms, Copyright Status and Copyright Notice)

Is there a way to get the metadata into the files without having to copy from a cell into each metadata field individually?

I am hoping some for sort of script, possibly...

Also, if only ONE of these fields needed updating in all of the files (i.e. Rights Usage Terms) can that be done?

I have Bridge 5.1 (and earlier versions CS3/CS4)

Stephen, is this script created for the Department of Defense? these looks like the fields one need to fill for their requirements...

It was created by/for the Visual Resources Association:

Looking at the list of affiliated orgs, there may be some cross-over of terms:

The VRA Import-Export script is hosted here:

I just found where Adobe Bridge is FREE for life.

However, I installed the scripts and it appears there are only certain tags that can be exported and/or imported.  So adding the custom XMP tags that I mentioned above does not seem possible.  I will just wait until one of you guys can provide some expert advice on which direction I should go. 

Thanks!
