Adds one or more items to a collection.
A data item object contains the _id and _owner fields. The response array must include the same items that were inserted, and each returned item must be added the _createdDate and _updatedDate fields.
However, data items can also be inserted without an _id field. In that case, it is the service provider's responsibility to generate a unique ID for each item.
