How to Use IPTC + XMP Metadata Auto-detection feature?

Our parser can identify the metadata in both IPTC and XMP formats to put the metadata into proper formatting. Here is how the detection will be done:

IPTC format:

• “Object Name” or “Headline” would be viewed as Title (“Headline” would be used if “Object Name” is not available);
  
• “Caption-Abstract” would be viewed as Description;
• “Keywords” would be viewed as Keywords.

XMP format:

• “Title” would be viewed as Title;
• “Description” would be viewed as Description;
• “Subjects” would be viewed as Keywords.
