---------------------------------------
    Resolution: Won't Do

> Add getter for vertex properties in vertex programs

>             Project: TinkerPop

> 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.
