Description of the commitment: National references to define the common specifications and nomenclatures are among the key mechanisms for coordinating activities related to the processing of public data produced and collected by public bodies at national and sectoral levels. It is recommended that most public bodies adopt standard codifications and classifications for the processing of public data, allowing interoperability between the different national and sectoral information systems, and streamlining the interconnection and mashup of data from different sectors for the purpose of developing services and applications based on these data. This commitment aims to promote and develop the use of national references for the definition of public data common specifications and nomenclatures, notably through : - Identifying a range of national references for the definition of common specifications and nomenclature for priority and cross-cutting public data, - Promoting and entrenching the use of these references by public bodies.

Problem/Background: The lack of standardized references and nomenclature for data that can be jointly used by public bodies, and the inadequate adoption and use of those already in place.

Identification of commitment objectives/expected results: Promote the opening of public data through: - Standardizing the mechanisms for data collection, classification and processing using a set of common codifications and categories, - Release public data in all its dimensions in accordance with unified standards specifications at the national level and in compliance with the international standards in the field, thereby promoting data exchange and reuse. - Urging public bodies to engage in opening public data and to adopt relevant mechanisms and references to that end

How will the commitment contribute to solve the public problem: - Setting practical mechanisms and unified standards to facilitate the public data release through the establishment of unified references concerning the classifications of private and common data between the various public bodies - Alignment with open data international standards and specifications, notably with regard to public data collection and classification.

Relevance with OGP values: - Transparency: Releasing public data in accordance with national standards and specifications with the aim of promoting exchange of data between public bodies and data reuse and exploitation in the preparation and implementation of public policies and decision-making. - The right of access to information: Enhancing public data access and reuse and improving its quality by providing a set of standard methodologies and mechanisms across the entire data chain.

Stages and implementation timeline: Appointing a steering committee to follow up the project December 2021; Identifying the priority sectors to be covered by these national nomenclature March 2022; Preparing the initial version of the nomenclatures and submitting them to the public structures consultation April 2023; Approving the final version of the nomenclatures and publish them in an open format July 2023; Experimenting the nomenclatures and generalizing their use within the public structures December 2023
