Hi Jason,

he asked about meta-properties, not vertex properties.

Cheers,

Daniel

Hi Jerry,

Yes, you can. You should check out the docs on vertex property cardinality http://docs.janusgraph.org/latest/schema.html#property-cardinality

If you don't use the schema manager to define a LIST or SET cardinality, it will default to SINGLE.

Hi,

can I use multi-value property on meta-properties?I want store the following data in one node :

{time:[1,--->{user:['a','b']}

          2,--->{user:['c','d']

          ......

}

I try the following command in gremlin console:graph = JanusGraphFactory.open("conf/janusgraph-hbase.properties")
conf = new BaseConfiguration()
conf.setProperty("gremlin.tinkergraph.defaultVertexPropertyCardinality","list")
g=graph.traversal()

g.addV('time','1','time','2')

g.V().properties("time").hasValue("2").property('user','a')

g.V().properties("time").hasValue("2").property('user','b')

g.V().properties("time")

==>vp[time->1]

==>vp[time->2]

g.V().properties("time").hasValue("2").properties()

==>p[user->b]

I find the property on time property only accept single value.thanks,Jerry
