> Many if not all vertex programs will mutate vertex properties during the computation process. For graphs that enforce a schema, this could lead to failure. JanusGraph, for example, when used with FulgoraGraphComputer and disabled automatic schema maker, will report error for vertex programs. See [https://gitter.im/janusgraph/janusgraph?at=626c568910cfc315bc5781a0]
>  
> This ticket proposes a getter method for each vertex program, which would return the vertex properties together with their data types needed in the computation. The graph providers or users could then leverage this information to create the corresponding schema.
