.Stat RESTful Web Service Cheat Sheet

Table of Content

Introduction

This cheat sheet is a quick reference description of the syntax and parameters for the .Stat RESTful API. It is adapted from the cheat sheet for the full SDMX RESTful API with examples added for the .Stat context and the unsupported elements removed.
You can also download this document as a .docx file.

Structural metadata queries

API Restful

Each .Stat space has a different web service entry point which should- replace http[s]://.Stat space WS/resource in the above syntax.
More options are available in the full SDMX REST API standard but are not present or have not been fully tested in the .Stat web service, and do not appear here.

Examples of structural metadata queries

These examples use an entry point of https://nsi-demo-oecd-staging.siscc.org This may be swapped out for your target space.

Use case Example querystring
All data structures, all versions https://nsi-demo-oecd-staging.siscc.org/rest/datastructure/all/all/all
A data structure and its references https://nsi-demo-oecd-staging.siscc.org/rest/datastructure/OECD.CFE/TOURISM_TRIPS/2.0?references=all
Full Dataflow with complete concept schemes, codelists, categorisations and constraints https://nsi-demo-oecd-staging.siscc.org/rest/dataflow/OECD.CFE/DOMESTIC@TOURISM_TRIPS/2.0?references=all
Full Dataflow with partial concept schemes, codelists, categorisations and content constraints containing only allowed and/or actually used items https://nsi-demo-oecd-staging.siscc.org/rest/dataflow/OECD.CFE/DOMESTIC@TOURISM_TRIPS/2.0?references=all&detail=referencepartial
Latest versions of all Codelists https://nsi-demo-oecd-staging.siscc.org/rest/codelist/all/all/latest
Latest versions of all codelists returned as stubs https://nsi-demo-oecd-staging.siscc.org/rest/codelist/all/all/latest?detail=allstubs
A Concept Scheme https://nsi-demo-oecd-staging.siscc.org/rest/conceptscheme/OECD.CFE/CS_TOURISM/latest
All category schemes (there is usually one), latest version https://nsi-demo-oecd-staging.siscc.org/rest/categoryscheme/all/all/latest
All agency schemes https://nsi-demo-oecd-staging.siscc.org/rest/agencyscheme/all/all/all

Note that with the detail=referencepartial query parameter, the server automatically applies the allowed content constraint on the codelists (and other ItemSchemes) and returns only partial (and thus shorter) codelists.
Using the query with the references=all, references=constraint, or references=actualconstraint parameter (with or without the detail=referencepartial parameter) returns a content constraint of type actual within the response if data was already uploaded. If such a content constraint is not returned by a .Stat Suite SDMX web service, then data was not yet uploaded or the underlying dataflow has not yetr been initialised.

Data queries

API Restful

Each .Stat space has a different web service entry point which should replace https://ws-entry-point in the above syntax.

API Restful

Note that in the .Stat Suite, the SDMX NSI web service is configured to apply Allowed ContentConstraints for both dimension values as well as attribute values to all data extractions:

config/Properties.json file:

{
  "applyContentConstraintsOnDataQueries": "true"
}

Examples of data queries

These examples use an entry point of https://nsi-demo-oecd-staging.siscc.org. This may be swapped out for your target space.

Use case Example querystring
All data for a Dataflow, time series view https://nsi-demo-oecd-staging.siscc.org/rest/data/OECD.CFE,DOMESTIC@TOURISM_TRIPS,2.0
All data for a partial key (Total Visitors measure), time series view https://nsi-demo-oecd-staging.siscc.org/rest/data/OECD.CFE,DOMESTIC@TOURISM_TRIPS,2.0/..TOTAL_VISITORS……..
All data for a partial key (Argentina, Total Visitors measure, Annual frequency), time series view https://nsi-demo-oecd-staging.siscc.org/rest/data/OECD.CFE,DOMESTIC@TOURISM_TRIPS,2.0/AU..TOTAL_VISITORS........A
Annual data for period 2010-2020 in a flat view https://nsi-demo-oecd-staging.siscc.org/rest/data/OECD.CFE,DOMESTIC@TOURISM_TRIPS,2.0/.........A?startPeriod=2010&endPeriod=2020&dimensionAtObservation=AllDimensions
Dataflow with only 1 observation returned for each of the matching series, starting from the first observation https://nsi-qa-stable.siscc.org/rest/data/OECD.CFE,DOMESTIC@TOURISM_TRIPS,2.0/all?firstNObservations=1
Dataflow with only 1 observation returned for each of the matching series, counting back from the most recent observation https://nsi-qa-stable.siscc.org/rest/data/OECD.CFE,DOMESTIC@TOURISM_TRIPS,2.0/all?lastNObservations=1
