Discussions has been done in the virtuoso mailing list [1]. > Specifically, inserting a triple with a value of type rdf:XMLLiteral caused a string "0" to be inserted. At that time a partial solution was to serialize the whole triple as TTL and use a stored procedure db.dba.ttl(...) to save the triple. This worked, but caused the triple to loose the datatype (see [2]). > This is also what is currently implemented. > Anyway, this solution is bad for other reasons, especially: > - performance is too bad (serializes any triple...) > - you still don't have the correct datatype (there are two tests with "Ignore" annotation in VirtuosoMGraphTest that witness this) > [1] http://sourceforge.net/p/virtuoso/mailman/message/31987368/ > [2] http://sourceforge.net/p/virtuoso/mailman/message/31992357/ -- This message was sent by Atlassian JIRA (v6.2#6252)
