Properties detail are missing from VertexLabel using JanusGraphManagement API.

[dishabehrani77]

I am using janugraph-1.0.0 and cassandra as backend storage.This is configuration file with cassandra details, janusgraph-cql/.properties

Now using gremlin console, I have added vertex and I am able to fetch it .

Now on trying to get the properties and the datatype, using JanusGraphManagemnet API.

I am unable to get the property details , Is there a away to get the details using management API ?

You can print the full schema via mgmt.printSchema(). That should also display the property keys.

However, mgmt.getVertexLabel().keys([...]), mgmt.getVertexLabel([...]).properties(), and mgmt.getVertexLabel([...]).mappedProperties() don't show any properties, because JanusGraph defines property keys globally and not per vertex label.
You can get all property keys via mgmt.printPropertyKeys().

If you want to only allow certain property keys on certain labels, then you can use schema constraints. These are not enabled by default so you have to enable them yourself.
If you use schema constraints, then you can actually find the allowed property keys for a given vertex label via mgmt.getVertexLabel([...]).mappedProperties().

keys() and properties() still won't work. They are only available in the API because JanusGraph stores schema information internally also as a graph and the JanusGraph vertices have these methods.
