This is obviously something I should know, but there you go :-) https://www.w3.org/TR/n-quads/#BNodes says: "A fresh RDF blank node is allocated for each unique blank node label in a document. Repeated use of the same blank node label identifies the same RDF blank node." I note it says "document", not "graph". However, when I look at the brilliant new WebDataCommons release, and download the first jsonld file from http://webdatacommons.org/structureddata/2016-10/stats/how_to_get_the_data.html, I get loads of blank nodes with the same name. It is most easily seen by extracting the owl:sameAs triples (why else would I be looking there? :-) ) Here is the start: _:b0 <http://schema.org/sameAs> <https://www.facebook.com/9fivers> <http://9five.com/blogs/9five-blog/12207401-9fivers-as-seen-on-tv-episode-2> . _:b0 <http://schema.org/sameAs> <https://twitter.com/9fivers> <http://9five.com/blogs/9five-blog/12207401-9fivers-as-seen-on-tv-episode-2> . _:b0 <http://schema.org/sameAs> <https://www.instagram.com/9fivers/> <http://9five.com/blogs/9five-blog/12207401-9fivers-as-seen-on-tv-episode-2> . _:b0 <http://schema.org/sameAs> <https://www.youtube.com/user/9fiveEyewear> <http://9five.com/blogs/9five-blog/12207401-9fivers-as-seen-on-tv-episode-2> . _:b0 <http://schema.org/sameAs> <https://www.facebook.com/androidayuda> <http://androidayuda.com/aplicaciones-android/> . _:b0 <http://schema.org/sameAs> <https://www.twitter.com/androidayuda> <http://androidayuda.com/aplicaciones-android/> . _:b0 <http://schema.org/sameAs> <https://plus.google.com/+androidayuda> <http://androidayuda.com/aplicaciones-android/> . _:b0 <http://schema.org/sameAs> <http://www.facebook.com/aplusapp> <http://aplus.com/a/beyonce-cfda-awards-speech> . _:b0 <http://schema.org/sameAs> <http://www.twitter.com/aplusapp> <http://aplus.com/a/beyonce-cfda-awards-speech> . _:b0 <http://schema.org/sameAs> <http://www.instagram.com/aplusapp> <http://aplus.com/a/beyonce-cfda-awards-speech> . _:b0 <http://schema.org/sameAs> <http://aplusapp.tumblr.com> <http://aplus.com/a/beyonce-cfda-awards-speech> . _:b0 <http://schema.org/sameAs> <http://youtube.com/aplusapp> <http://aplus.com/a/beyonce-cfda-awards-speech> . _:b0 <http://schema.org/sameAs> <http://pinterest.com/aplusapp> <http://aplus.com/a/beyonce-cfda-awards-speech> . _:b0 <http://schema.org/sameAs> <http://plus.google.com/+Aplusapp> <http://aplus.com/a/beyonce-cfda-awards-speech> . Am I misunderstanding the NQuad document, or should there be (presumably) 3 different blank nodes here? Best Hugh
