---------------------------------------------
I think we'll ultimately solve this one with TINKERPOP-1592 by letting users
better specify the detachment model.
> API Alignment Between Java Gremlin Graph Structure and GLVs
> -----------------------------------------------------------
>
> Key: TINKERPOP-1474
> URL: https://issues.apache.org/jira/browse/TINKERPOP-1474
> Project: TinkerPop
> Issue Type: Improvement
> 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?
