>                 URL: https://issues.apache.org/jira/browse/TINKERPOP-1474
>             Project: TinkerPop
>          Issue Type: Bug
>          Components: io, language-variant
>    Affects Versions: 3.2.2
>            Reporter: Adam Holmberg

> The current Java GraphSON implementation and that in the Python GLV leave some question about what *should* be returned from a simple traversal like `g.V()`.
> The java implementation presently assumes that properties could be present and returns a DetachedVertex: https://github.com/apache/tinkerpop/blob/master/gremlin-core/src/main/java/org/apache/tinkerpop/gremlin/structure/io/graphson/GraphSONSerializersV2d0.java#L420-L433
> The python implementation assumes no such thing and returns something more reminiscent of a ReferenceVertex: https://github.com/apache/tinkerpop/blob/master/gremlin-python/src/main/jython/gremlin_python/structure/io/graphson.py#L238-L242
> Is the java version overreaching, and should not expect properties unless a step calls for them (e.g. ` g.V().valueMap()` or `g.V().values('name')`, or should the Python version be expanded?
> Is there something we can do to establish guidelines for this, and align these APIs?
