Main metadata loader is found here. These generally follow the Dublin Core namespace for XMP - see RDF/XML specification (base format) and Adobe's XMP specifications for a nice table of expected tags (<x:xmpmeta xmlns:x="adobe:ns:meta/" x:xmptk="XMP Core 4.4.0-Exiv2">).
These are the highest priority tags processed by pigallery2:
metadata.keywords = exif.dc.subject;
metadata.title = exif.dc?.title?.value;
metadata.caption = exif.dc?.description?.value;
metadata.creationDate = exif.DateTimeOriginalmetadata.creationDate;
metadata.rating = exif.xmp.Rating;
