-- Gets meta data about a dataset by identity and dataset name. With Amazon
-- Cognito Sync, each identity has access only to its own data. Thus, the
-- credentials used to make this API call need to have access to the
-- identity data.
--
-- This API can be called with temporary user credentials provided by
-- Cognito Identity or with developer credentials. You should use Cognito
-- Identity credentials to make this API call.
