About Multi-value dimensions for JSON data

In Druid data-formats doc, it said that Dimensions can have multiple values for TSV and CSV data. To specify the delimiter for a multi-value dimension, set thelistDelimiter in the parseSpec.
It is not explain for JSON data, can dimensions have multiple values too?

And if JSON support multiple values, what is data format of multiple values? JSON array?

For example I have a nested dimension which is named device, is follow sample is right?

{"timestamp": "2013-08-31T01:02:33Z", "device": ["mobile","ios","iphone 6"], "language" : "en", "time": 1200}

Hi James,

Multivalue is supported for JSON, and you’re correct, a JSON array should be used.
