Fan, I'm sorry about the delay, but I finally got the Rya/Vagrant/OpenRDF Workbench VM into a good spot. Can you test out the instructions at:
https://github.com/amihalik/incubator-rya/blob/RYA-4/extras/vagrantExample/src/main/vagrant/readme.md Once you run this VM, it should be straightforward to upload and query your data through OpenRDF Workbench. For instance, once you connect Rya and OpenRDF Workbench, you can open the Workbench, click on "Add", and cut-and-paste your ntriples into the "RDF Content" field. Then you can click on "Query" and run this SPARQL query: select * where { <http://mynamespace/ProductType1> ?p ?o. } --Aaron On Thu, Dec 17, 2015 at 1:00 PM Fan Yang <[email protected]> wrote: > Hi Dr. Adina, > > I named my $RDF_DATA file as ntriplesFile and put it under the folder same > as Java code’s.
