The below screenshot shows that dt/dd tags do not line up properly. Notice that "Make" does not line up with its value "NIKON". You can also see in the Inspector that there are two successive dt tags. I believe this is due, in this case, to "ImageDescription" not having a value in the RDF data.

I'm willing to create a PR with a fix if someone could point me to the correct place in the code. I believe it would be somewhere around here.
