ACTION-464

Hi,

I completed my ACTION-464 which was to review the XMP files (RDF and TTL).

As I used some new tools for that review, I had the curiosity to test
them on the other testsuite files... and I'm ashamed to say that I had
missed *a lot* of issues with the files I reviewed previously :-/

Here are all the files I modified (+ two I generated, namely the TTL
files for IPTC and Youtube), and the reason for the modifications.
