 * Good to hear from you again, and thanks for your question and for the screen 
   shot of your custom field rule; very helpful. I hope I can clear up some confusion
   around how the term “metadata” is used in WordPress.
 * In WordPress, the term “metadata” is often used interchangeably with “custom 
   fields”. WordPress also has a separate data structure, “Attachment Metadata”,
   that contains a number of elements describing a Media Library item. You can see
   this special structure in the “Attachment Metadata” text box on the Media/Edit
   Media admin page. In MLA, the `meta:` prefix is used to access these elements.
   To access a custom field, MLA uses the `custom:` prefix.
 * For your application, something like `href="{+custom:links+}"` should work. I’m
   not sure why you used `links-url` as the field name because your rule shows the
   name to be simply `links`. If you need to URL encode the field content you can
   use something like `href="{+custom:links,url+}"`. The `,url` suffix is an MLA
   format/option code that applies the encoding.
 * You might have also noticed the “Attachment File Metadata” text box on the Edit
   Media admin page. This displays the metadata embedded in the file itself using
   the IPTC, EXIF and XMP standards. Yet another variation on the “metadata” theme.
 * I hope that gets you started on a solution for your application. I am marking
   this topic resolved, but please update it if you have problems or further questions
   regarding the above suggestions. Thanks for your interest in the plugin.
