How to retrieve dataset metadata

To retrieve metadata for specific dataset it's necessary to send HTTP GET request to the following URL:

http://dptest.ncsi.gov.om/api/1.0/sdmx/{sdmxVersion}/<datasetId>

Here datasetId is id of corresponding dataset returned by enumeration endpoint. Response will contain Structure message with nested information about dataset dimensions represented by CodeLists and dataset's structure described as key family components (SDMX 2.0) or dataset structure components (SDMX 2.1).

GET http://dptest.ncsi.gov.om/api/1.0/sdmx/2.1/OECDEO90
