Hi Hamid,
To get Turtle from the SPARQL endpoint, use a CONSTRUCT query. In the simple
case where you want to return the whole graph, use this query:
CONSTRUCT WHERE { ?s ?p ?o }
You can try this by going to /tbl/sparql, pasting the query into the form,
choosing your asset collection from the dropdown, and checking the “Include
imports” box.
A corresponding curl command would be something like this (assuming an asset
collection called “t1” and EDG Studio):
curl -d default-graph-uri=urn:x-evn-master:t1 \
-d "query=CONSTRUCT WHERE { ?s ?p ?o }” \
-d with-imports=true \
-d format=turtle \
http://localhost:8083/tbl/sparql
Hope that helps,
Richard
