Answers to Frequently Asked Questions
A complete listing of dataset IDs available to query can be retrieved via building a Dataset Structure Definition query message (refer to section 3) with no 'Key Family' metatags. Through calling the GetDataStructureDefinition web service and passing the DSD query message, a DSD output with a complete listing of datasets will be returned.
By submitting a Dataset Structure Definition query message (refer to section 2.4.3) with a specific dataset ID, a list of dimensions and its associated dimension members are returned. In the below example (extract from CPI DSD) the ‘CodeList’ is the identifier for the dimension ‘Region’ (can be verified via the ‘Concept ID’ located further down in the DSD) and the ‘Code Value’ is the identifier for dimension member’s i.e. code value of 1 = Sydney.
There is a 10 minute session time limit for users to download datasets from the SDMX Web Service. So any requests that require more than 10 minutes to download will result in a "500 - Internal server error." error message being returned to the user's application. Users should reduce the number of dataset variables requested i.e. rather requesting data from year 1900 to year 2012, request data from year 2000 to year 2012. Should users require large amounts of data, try making multiple small SDMX requests to retrieve the data needed.
Large datasets that users should be aware of and customise queries accordingly are: BA-GCCSA, BA-SA2, HF, IIP_DSID5671, LF, MECH_EXP, MECH_IMP, NRP7.
