Re: How to load RDF dump

You can either use jena distribution's tdbloader script into the folder "db" (but stop fuseki first), or if the nt file is small enough (e.g. 50 MB) then you can also upload it in the browser interface (but make sure you run fuseki 2 for this). If you run Linux and "dB" is blank, then tdbloader2

Re: Construct query

Important to notice is that the CONSTRUCTed triples are just returned to the caller, they are not added to the graph. It can be useful to reshape RDF, e.g. swap properties or simplify relationships. On 30 Sep 2016 10:32 a.m., "Lorenz B." wrote: > SPARQL
