Istat database, available through I.Stat dissemination system, is also fully accessible in machine-to-machine mode through the ISTAT webservice, which uses the standard protocol Statistical Data and Metadata eXchange (SDMX), adopted for statistical data transmission by the most important international organizations.
Starting from July 2022, Istat will progressively display its data through a new dissemination system, the IstatData, natively based on SDMX-RI. This system will guarantee better usability of data, thanks to dashboards, graphs, customizable layouts and filterable datasets.
The relative diffusion in machine-to-machine mode will take place through following End-Point: https://esploradati.istat.it/SDMXWS
The new dissemination system will run alongside the old one until the end of 2022. In 2023 will be removed I.Stat and old webservice.
In order to ensure the display continuity of the data acquired through the webservice, users are advised to modify their SDMX queries by the end of 2022.
New web service will maintain compatibility with the previous one for most of the artifacts used; codelist and dataflow will remain unchanged.
However, users will have to consider the following small differences:
- Query REST: for some dataflows the position of the dimensions will change (in the corresponding DSD).
- Query SOAP: for some dataflows the name of the dimensions will change (in the corresponding DSD).
To facilitate queries conversion, Istat provides a simple excel tool that will allow users:
- Automatically modify the REST queries on new environment, starting from queries prepared for the old webservice (single query tool, multiple query tool).
- Compare names of dimensions on the two environments, starting from the dataflow (tool for dataflow search and dimension transcoding).
