Interoperability of data bases on soil carbon to address the 4 per Initiative – DATA4C+

The DATA4C + project is part of the open science (RDA) and soil carbon initiatives (4 per 1000 in particular). In order to meet the objectives of these initiatives, there is a great challenge to reference, in databases, not only the analyzes but also the associated metadata and to make databases interoperable. Based on this observation and the leading role played by CIRAD, INRA and IRD at national and international level on the topic of soil carbon, the DATA4C + project has the following objectives: (OS1) Define rules of good practice to describe the data in the soil carbon databases and provide them with consistent information; (OS2) Analyze the computer and legal barriers for interoperability between soil carbon databases and soil management modes in order to propose solutions for alleviating them; (OS3) Experiment with the implementation of methodological solutions formulated by the project in a French overseas department; (OS4) Exchange and disseminate internationally on the project. The results of DATA4C + are intended to be integrated into the practices and tools of CIRAD, INRA and IRD within the framework of their respective strategies relating to digital and open science. Beyond the soil carbon community, the semantics validated in the DATA4C + project will be published / disseminated and will be used by other scientific communities. In addition, solutions / options from the DATA4C + project may also be valid for other soil parameters and then support other teams. In addition, the availability of soil carbon data and metadata will eventually have very different targets: States, engineering offices ...
