Hi Bernadette, I have just submitted the fowlloing pull request on Github https://github.com/w3c/dwbp/pull/390 I did not merged it as I prefer to leave to the editors the last word on it :) With this pull request I have made some corrections on the DQV example included in BP doc, and I have re-added the related rdfa for human readable HTML example. I have realized that the DQV example in BP document uses different URI than the turtle generated by RDFa ( e.g, :stops-2015-05-05.csv is used in the bp document whilst #timetable-001-CSV is used in the rdfa generated turtle). If not too much impacting in terms of changes, I suggest to consider to make the uris used in the two more consistent.
