Add edg:subjectArea via API

[Vaisakh Babu]

I am creating a new asset using API ("{base_url}/createAssetCollection") and importing the RDF data ("{base_url}/tbs/importRDFFile"). 

Is it possible to add edg:subjectArea also via API? I tried keeping it in the RDF data, but topBraid EDG removed this.

You can add any triple, including edg:subjectArea, either using ADS JavaScript or through SPARQL INSERT.

In ADS it would be graph.add(masterGraph, edg.subjectArea, area)

SPARQL INSERT via API throws error "Invalid SPARQL query string: Encountered " "insert""

here is the sparql for ref: 

INSERT {
?s <http://edg.topbraid.solutions/model/subjectArea> <urn:x-tb-governance:test_subArea> .
}
WHERE { ?s <http://www.w3.org/2000/01/rdf-schema#label> "Test 4". }

Maybe you have passed in the query like with the query protocol, but it should look like

Oh yes. Thanks Holger. I was using 'query' parameter instead of 'update'. My bad.
