Mongoose SchemaTypes Syntax: Array of ObjectIds

Is this

blog: [{type: Schema.Types.ObjectId, ref: 'BlogEntry'}]

the same as this

blog: {type: [Schema.Types.ObjectId], ref: 'BlogEntry'}

or is the second example incorrect?

Both are correct, but they're not the same. In the first one, the key blog is an array of objects. Each object contains two keys: type and ref where type is a single ObjectId and ref is already define. In the second one the key blog is no longer an array but a single object. Now, in this object the key type is an array of ObjectId.
