I export images using Lightroom, with keywords in the IPTC metadata.

I then use exiv2 to add keywords.

I then upload my images to an online website. The website sees the keywords added by Lightroom, but not the keywords added by exiv2. I can see the keywords added by exiv2 in the windows or linux file explorer, so I know they have been properly embedded in the image.

What might be causing this website to be "blind" to the changes made to the files?

The website is reading metadata from xmp and not iptc

The wonderful thing about standards is that there are so many to choose from. In the case of keywords, there are two standardized locations:

Iptc.Application2.Keywords
Xmp.dc.subject

and five application-specific locations:

Exif.Image.XPKeywords
Xmp.acdsee.categories
Xmp.digiKam.TagsList
Xmp.MicrosoftPhoto.LastKeywordXMP
Xmp.MicrosoftPhoto.LastKeywordIPTC
