All these are good news. But one of the important stuff, as far as I know still to be addressed is, are all the graphs produced by RDF graph generator are meaningful for a use-case. In other words, do we have methods to ensure that the elements (subject, object, predicates) of an RDF trillion store are of the quality to produce meaningful results in such an automated process of building graphs? Until that is done for specific area of our research, all these advances are hypothetical

Also note that there is a live 55 Billion+ triples instance of the LOD 
Cloud cache that showcases what's always been possible re. Linked Data, 
RDF, and machine readable Entity Relationship Semantics.
