Hi Bernadette, It looks good to me. Just a minor remark, in the previous version of the human readable example page, I had inserted some RDFa annotations for DQV statement that have disappeared in the current version. Actually the DQV related triples are not distilled anymore by the RDFa 1.1 validator ( see [2]). Not a real problem, but I am mentioning it since I am not sure whether that was meant to be or it is an unexpected side effect of latest page changes.
