Thanks for your question, which is a variation on some earlier topics. As you’ve discovered, the labels Adobe tools like Photoshop (and Lightroom and Illustrator) give to metadata fields can be a challenge to map to their IPTC, EXIF and XMP equivalents. Here is an earlier topic with some guidance on using MLA to investigate your images:
How to use exif_read_data and ALL_IPTC
You can also find more information here:
Lightroom IPTC Description Field > WordPress Description Field
One experiment I performed was to go through the Description, IPTC and IPTC Extension tabs of the Photoshop File/File Info dialog box to fill in all the fields with a descriptive value. For example, I entered “IPTC Title” in the “Document Title” field and “IPTC Job Title” in the “Author Title” field. I then uploaded the image to MLA and used the ALL_IPTC
feature to produce this result:
array (
‘1#090’ => ‘%G’,
‘2#000’ => ‘2’,
‘2#120’ => ‘IPTC Description’,
‘2#122’ => ‘IPTC Description Writer’,
‘2#105’ => ‘IPTC Headline’,
‘2#040’ => ‘IPTC Instructions’,
‘2#080’ => ‘IPTC Creator’,
‘2#085’ => ‘IPTC Job Title’,
‘2#110’ => ‘IPTC Provider’,
‘2#115’ => ‘IPTC Source’,
‘2#005’ => ‘IPTC Title’,
‘2#055’ => ‘20121130’,
‘2#060’ => ‘000000+0000’,
‘2#090’ => ‘IPTC City 2’,
‘2#092’ => ‘IPTC Sublocation’,
‘2#095’ => ‘IPTC State/Province 2’,
‘2#101’ => ‘IPTC Country/Territory 2’,
‘2#100’ => ‘US’,
‘2#103’ => ‘IPTC Job Identifier’,
‘2#015’ => ‘Cat’,
‘2#020’ => ‘ARRAY(Supplemental,another)’,
‘2#025’ => ‘IPTC2 Keyword’,
‘2#116’ => ‘IPTC ? Corbis. All Rights Reserved.’, )
You can also look at the Photoshop “Raw Data” tab to see if the EXIF or XMP values might be easier to use. If you use the “ALL_” pseudo values on a few of your images you should be able to decide the best values to use for your application.
I am marking this topic resolved, but please update it if you have problems or further questions regarding the above suggestions. If you can post a link to one or more of your images I can have a look and give you more specific guidance. Thanks for your interest in the plugin.
