Peter, I mispoke about SPARQL and GeoSPARQL. My apologies for the confusion. The triple is valid and it loads, as per the simple test I have at: http://kingsley.idehen.net/DAV/home/kidehen/Public/Linked%20Data%20Documents/Nanotations/test.ttl . or: curl -i http://kingsley.idehen.net/DAV/home/kidehen/Public/Linked%20Data%20Documents/Nanotations/test.ttl Thus, we need to figure out if this is something to do with the version you are workings with (as my versions are typically hot of the press etc..). -- Regards, Kingsley Idehen Founder & CEO OpenLink Software (Home Page: http://www.openlinksw.com) Weblogs (Blogs): Legacy Blog: http://www.openlinksw.com/blog/~kidehen/ Blogspot Blog: http://kidehen.blogspot.com Medium Blog: https://medium.com/@kidehen Profile Pages: Pinterest: https://www.pinterest.com/kidehen/ Quora: https://www.quora.com/profile/Kingsley-Uyi-Idehen Twitter: https://twitter.com/kidehen Google+: https://plus.google.com/+KingsleyIdehen/about LinkedIn: http://www.linkedin.com/in/kidehen Web Identities (WebID): Personal: http://kingsley.idehen.net/dataspace/person/kidehen#this : http://id.myopenlink.net/DAV/home/KingsleyUyiIdehen/Public/kingsley.ttl#this
