Standards used

To date, there are nearly 20 publication standards proposed on the national schema.data.gouv repository.

Due to a lack of maturity in the description of metadata, and although the situation has improved a lot by 2022 thanks to the efforts of the main technical platforms (data.gouv.fr and ODS), it remains difficult to measure the adoption of existing standards when publishing data.

To date, we can qualitatively estimate, without a reliable indicator, that the published data respecting a standard are of the order of 1% of the total number of datasets (covered or not by a standard) and of 15% when the data are subject to a standard.

This shows that the majority of data is still not very standardized and therefore not very interoperable.

Efforts must be made to:

1. Raise awareness of the standards,

2. Ensure the adoption of standards (tools),

3. Measure adoption (mandatory field in metadata),

4. Increase the number of standards to progressively cover all published data (thus extending the framework of the Common Core of Local Data)
