Hi Arne,
I'm no expert, but as per my experience, the results from OrientDB will
contain metadata such as @type, @class etc.
How I solved the problem was to pass through the OrientDB results via a
JavaScript function, create a JavaScript object as per the schema I want
and return the stringified version of the JavaScript object that I've
created.
Note: You can use the JSON.stringify() function to convert a JavaScript
object to JSON. However, I experienced the function not working on Java 1.8
- update 40.
Hope this helps.
Cheers
Omega
