+		   the cell value. The cell value is an object that may contain 
+		   one of the following fields depending on the value type:

+For instance you can pass the following queries to the endpoint
+
+```
+create graph ?test;
+
+insert data into ?test {
+   /foo<id> "knows"@[] /bar<id>.
+   /foo<id> "follows"@[] /bar<id>
+};
+
+select ?s,?p,?o,?k,?l,?m
+from ?test
+where {
+  ?s ?p ?o.
+  ?k ?l ?m
+};
+```
+
+The endpoint will execute each of the statements in order and return and array
+of JSON formated objects, one for each query. For the above example you should
+get the following JSON on a newly started server:
+
+```

+	"query": "create graph ?test;",
