How to import JSON-LD into Virtuoso

问题

I'm using Virtuoso at AWS.

I want to get JSON-LD Data using SPARQL query. Because I'm making opendata that is JSON-LD Content-type.

But, I can not import JSON-LD file into Virtuoso Conductor.

So, do you know how to import JSON-LD into Virtuoso?

回答1:

To import JSON-LD into Virtuoso you need to install the Virtuoso Sponger Middleware module. Once installed, you can use Sponger pragmas and/or URL patterns to facilitate imports from documents comprised of JSON-LD content.

SPARQL pragma example:

define get:soft "replace" 
SELECT * FROM <{JSONLD-DOC-URL}> 
WHERE {?s ?p ?o}.

Web Service URL Patterns:

• first time

  http://{your-virtuoso-instance-cname}/about/html/{JSONLD-DOC-URL}
  

• to replace/overwrite data stored in Virtuoso hosted named graph (internal document)

  http://{your-virtuoso-instance-cname}/about/html/{JSONLD-DOC-URL}?sponger:get=replace
  

• to add/append to data already stored in Virtuoso hosted named graph (internal document)

  http://{your-virtuoso-instance-cname}/about/html/{JSONLD-DOC-URL}?sponger:get=add
