I'm sure it's something simple, but I've beaten my head against the wall long enough that I'm going to ask for some help. I'll explain the scenario first in case my approach is fundamentally wrong.
For a proof of concept, I need to be able to get data and create data easily (hopefully via a restful web service). To query data, I've had a lot of success with the SPIN select templates. Those are awesome, easy to create and consume for a client. Now I need to be able to easily insert data. I did not see a way to do that with SPIN Templates, but if that is possible, I would love to know how to do that. Instead, I thought a SPARQLMotion web service might be the best approach. I'm playing around with a simple script to insert a name with the vCard ontology. I have two variables, first and last name. Then I send that to an Apply Construct module. Then I send that to a Perform Update. <https://lh5.googleusercontent.com/-DOZD0UWjHAc/U6ylE_1ZwbI/AAAAAAAAC0I/sPbx7LaeIWk/s1600/SparqlMotionGraph.PNG> Inside the Apply Construct module, I have the following statement: CONSTRUCT { ?nameUri a ns:Individual . ?nameUri ns:given-name ?firstName . ?nameUri ns:family-name ?lastName . } WHERE { BIND (URI(CONCAT("http://names.example.com/";, ?lastName, "_", ?firstName)) AS ?nameUri) . } And Inside the Perform Update, I have the following statement: INSERT { ?s ?p ?o . } WHERE { ?s ?p ?o . } I figured that would insert all the triples generated by the apply construct. When I hit the perform update, the graph contains the correct triples, but upon stepping into the perform update module, I get a nullPointerException. I'm figuring the module doesn't know where to insert the triples, but I don't know how to fix that if it is the issue. Any help would be much appreciated.
