How to store JSON in Virtuoso

Does Virtuoso have a document store similar to MongoDB where i can JSON Objects and retrieve them programmatically?

Apologies for the very late response.

JSON is stored in Virtuoso by way of transformation to RDF associated with a Named Graph (a Document identified by an IRI).

You can retrieve the stored data using SPARQL Queries i.e., SELECT, CONSTRUCT, or DESCRIBE.

I also tweeted out an example of JSON processed in the manner described above.

Let me know if this helps, or if additional information is required.
