OneGeochemistry: Creating a Global Network of Distributed Geochemical Data Systems through International Collaboration and Consensus.

The OneGeochemistry CODATA Working Group seeks to establish a global network of interoperable geochemical data systems to maximise the capacity of research investments in laboratory analysis to resolve challenges to science and society. As geochemical data are heterogeneous and very fragmented, a collaborative solution is required to interlink the distributed systems to facilitate seamless access to the wealth of data existing internationally across the research, government and industry sectors. Fundamental to this ambition is the development of consensus-driven community standards that will make geochemical data not just Findable, Accessible, but genuinely Interoperable and Reusable to both humans and machines. OneGeochemistry was started in 2018 by a small international group of data providers and research infrastructures who recognised that reporting and exchanging geochemical analytical data online requires agreed, consistent protocols. The goal is to promote geochemical protocols internationally and ultimately facilitate their adoption widely enough to become globally accepted data standards. To support the initiative, OneGeochemistry has also sought and obtained endorsement from international professional societies and unions. However, as the demand for cross-domain data integration grows, harmonising protocols and standards within the geochemistry community is not enough. From 2022-2024 OneGeochemistry also participated in the CODATA/RDA-led EU-Horizon WorldFAIR project as one of 11 case studies to advance the interoperability and reusability of data across disciplines. This poster will showcase what has been achieved so far to both facilitate the creation of a global network of distributed geochemical data systems and to ensure that geochemical data can contribute to cross-domain research challenges.
