API.EWS.05 SDMX example

Below is a simplified but structurally correct SDMX-JSON example for the DCI DCI_MEMBER_STATISTICS dataflow.

Scenario:

Request

GET /data/DCI_MEMBER_STATISTICS/AREA001.*.*.ALL.2026

Meaning:

• Area: District A

• Sex: all

• Disability status: all

• Age group: all

• Year: 2026

The expected result returns:

Sex	Disability	Count
Female	With disability	3421
Female	Without disability	60391
Male	With disability	2876
Male	Without disability	58642

How to read the series keys

The series key:

0:0:0:0

maps to the dimension indexes:

REF_AREA   0 = AREA001SEX   0 = FDISABILITY_STATUS   0 = TRUEAGE_GROUP   0 = ALL

Therefore:

"0:0:0:0": {   "observations": {      "0": [3421]   }}

means:

District A Female With disability All ages OBS_VALUE = 3421
