Re: Property keys unique per label

Janus describes itself like this

a scalable graph database optimized for storing and querying graphs containing hundreds of billions of vertices and edges distributed across a multi-machine cluster

but my feeling when using it is that this definition means "a simple schema with billions of vertices/edges" and not "a graph with a large schema". This limitation with properties is an example. What I mean is a graph big enough that vertices on one corner of the graph represent something entirely different (semantically) from vertices on the far end of the same graph. So for example, I could use property "age" with a meaning, but use it with a completely different meaning somewhere else on the graph. Because properties names are unique, I must namespace them, for example "contextA.age" and "contextB.Age". But if nodes could be grouped by "context" for example, or maybe properties could be bound to labels, I would not need to namespace them and their datatype would only depend by their context.
I don't know if this makes sense to others, but to me it does.

Hi Laura,

Indeed, unique property key names are a limitation. But to be honest: if two properties have a different data-value type I would say these are different properties, so why give them the same name?
