Abstract: & & Envisioned as one solution to data challenges of the International Polar Year (2007-2008), the Copernicus data journal Earth System Science Data (ESSD) has developed into a useful rewarding data-sharing option for an unprecedented array of researchers. ESSD has published peer-reviewed descriptions of more than 500 easily- and freely-accessible data products, from more than 4000 data providers archiving their products at more than 100 data centres. ESSD processes and products provide a useful step toward Findable, Accessible, Interoperable, Reusable (FAIR) expectations but also a caution about implementation.& & & & For ESSD, findable and accessible derive from the journal& #8217 s consistent mandate for open access coupled with useful title, author, abstract and full-text search functions on the publisher& #8217 s website (which lead users quickly to data sources) and excellent (but varied) topical, geographic, textual and chronologic search functions of host data centres. Due to an intense focus on data reliability and reusability during peer review of data descriptions, ESSD-referenced data products achieve very high standards of accessibility and reusability. ESSD experience over an amazing variety of data products suggests that & #8216 interoperability& #8217 depends on the intended use of the data and experience of users. Many ESSD-published products adopt a shared grid format compatible with climate models. Other ESSD products, for ex le in ocean biogeochemistry or land agricultural cultivation, adopt or even declare interoperable terminologies and new standards for expression of uncertainty. Very often an ESSD publication explicitly describes data collections intended to enhance interoperability within a specific user community, through a new database for ex le. For a journal that prides itself on ersity and quality of its products published in service to a very broad array of oceanographic, terrestrial, atmospheric, cryospheric and global research communities, the concept of interoperability remains elusive.& & & & Implementing open access to data has proven difficult. FAIR principles give us guidelines on the technical implementation of open data. However, ESSD& #8217 s experience (involving publisher, data providers, reviewers and data centres) in achieving very high impact factors (we consider these metrics as indicators of use and reuse of via ESSD published data products) can serve as a guide to the pursuit of the FAIR principles. For most researchers, data handling remains confusing and unrewarding. Data centres vary widely in capability, resources and approaches even the & #8216 best& #8217 (busiest) may change policies or practices according to internal needs independent of external standards or may - unexpectedly - go out of service. Software and computation resources grow and change rapidly, with simultaneous advances in open and proprietary tools. National mandates often conflict with international standards. Although we contend that ESSD represents one sterling ex le of promoting findable, accessible, interoperable and reusable data of high quality, we caution that those objectives remain a nebulous goal for any institution - in our case a data journal - whose measure of success remains a useful service to a broad research community.& &

Abstract: & & When researchers collect or create physical s les they usually assign a user-generated number to each s le. Subsequently, that s le can be submitted to a laboratory for analysis of a variety of analytes. However, as geoanalytical laboratories are generating ever increasing volumes of data, most laboratories have automated workflows and it is no longer feasible for laboratories to use researcher-supplied s le numbers, particularly as it is not guaranteed that user-supplied numbers will be unique in comparison to numbers submitted by other users to the same laboratory. To address this issue new, laboratory-generated numbers may be assigned to that s le.& & & & Moreover, as a single laboratory rarely has the capability to offer all analytical techniques, in idual s les tend to move from laboratory to laboratory to acquire the desired suite of analytes.& Each laboratory may implement a different number to that s le. At the conclusion of their project, the researcher may submit the same s le to a museum or institutional repository, where the s le will be assigned yet another institution-generated number to ensure that all s les are uniquely identified in their repository.& & & & & Ultimately, by the time the researcher submits an article to a journal and wants to identify s les in the text or tables, they may have a multitude of locally-generated numbers to choose from. Not one of the locally assigned numbers to that s le can be guaranteed to be globally unique. It is also unlikely that any of these local numbers will be persistent over the longer term (decades), or be resolvable to enable the location of the identified resource or any information about it elsewhere on the web (metadata, landing page, services related to it, etc).& & & & Globally unique, persistent, resolvable identifiers such as the IGSN play a critical role in the unique identification of geoanalytical s les that pass between systems and organisations: they cannot be duplicated by another researcher, laboratory or s le repository. They persistently link to information about the origin of the s le to personas in the creation of the s le (collector, institution, funder) to the laboratory data and their creation (analyst, laboratory, institution, funder, data software) and to the s le curation phase (curator, repository, funder). They connect the phases of a s le& #8217 s path from collection in the field to lab analysis to the synthesis/research phase to the publication to the archive. Globally unique s le identifiers also enable cross linkages to any artefacts derived from that s le (images, analytical data, other articles). Further, identifiers like IGSN enable sub s les or s le splits to be linked back to their parent s le, creating a holistic picture of any information derived from the initial s le.& & & & & Hence, best practice is clearly to assign the globally unique resolvable identifier to the initial resource. Like a birth certificate, the identifier can be carried through the progressive stages of the research & #8216 life-cycle& #8217 including laboratory analysis, generation of further data, images, publication, and ultimately curation and preservation. Where any subs les are derived, they, and any data generated on them, can be linked back to the parent identifier.& &

Abstract: & #8216 WorldFAIR: Global cooperation on FAIR data policy and practice& #8217 is a European Commission funded project composed of 11 discipline and cross-discipline case studies drawn together by CODATA, the Committee on DATA of the International Science Councils Committee on DATA, and is supported by the Research Data Alliance. WorldFAIR is a erse, global community effort that currently has 19 partners located in Africa, Australasia, Europe, and North and South America, representing organisations from research, government and industry. The 11 in idual case studies are drawn from Chemistry, Nanomaterials, Geochemistry, Social Surveys, Population Health, Urban Health, Bio ersity, Agriculture, Oceans, Disaster Risk Reduction and Cultural Heritage. The WorldFAIR project aims to focus on the interoperability and reusability of research data products from both within and across disciplines by creating a Cross-Domain Interoperability Framework (CDIF).The foundation of the CDIF will be a series of FAIR Implementation Profiles (FIPs) which will be used as a methodology for in idual communities to express their FAIR practices and decisions for each of the 15 in idual FAIR guiding principles.& As an ex le of how this will work, the WorldFAIR& #8217 s Geochemistry case study is led by OneGeochemistry, an international network of national geochemical data infrastructure organisations. Initially an informal network with representatives from AuScope (Australia), GEOROC (Germany), EPOS Multi-scale Laboratories (Europe), EarthChem (US) and AstroMaterials (US). With the advent of WorldFAIR, OneGeochemistry has formalised it& #8217 s governance structure and is now a CODATA Work Group. Over the life of WorldFAIR, OneGeochemistry will work towards developing a community prototype FAIR Implementation Profile(s) for in idual geochemical techniques, including the minimum defined variables, through workshops and consultations, and subsequently be responsible for their communication, publication and dissemination. The Geochemistry case study will work closely with the Chemistry case study and leverage relevant chemical standards and vocabularies wherever possible.Through the development of community lead FAIR Implementation Profile(s) for geochemistry within a global Cross-Domain Interoperability Framework (CDIF), WorldFAIR and OneGeochemistry are both advancing the adoption of the FAIR data principles within Geochemistry and simultaneously enabling interoperability of geochemical research data products across the other ten discipline case studies.

Abstract: The GEOROC database is a leading, open-access source of geochemical and isotopic datasets of igneous and metamorphic rocks and minerals. It was established 24 years ago and currently provides access to curated compilations of rock and mineral compositions from ,600 publications ( million single data values). The Digital Geochemical Data Infrastructure (DIGIS) initiative for GEOROC 2.0 is now building a connected platform capable of supporting the erse demands of digital, data-based geochemical research: including modern solutions to data submission, discovery and access.One of the challenges for maintaining a high quality, up-to-date database such as GEOROC is consistent data entry. Historically, data were compiled manually from the academic literature by trained curators. This manual data entry process is slow, resource-intensive and prone to errors. Exacerbated by the lack of best-practices or standards for analytical geochemical data reporting, the quality and completeness of data and metadata compiled in this way are highly variable. A possible solution to this challenge is offered by domain-specific repositories: in part driven by demands of some funders and publishers to make all research data publicly available, data producers increasingly publish their research datasets, affording repositories a unique opportunity to impose consistent standards and quality. Following these developments, DIGIS established a domain repository with DOI minting capabilities in 2021 to support independent data submission by authors. In principle, these data submissions may comprise new analytical results as well as compilations of previously published data (& #8220 expert datasets& #8221 ). DIGIS also uses its repository for versioning of the GEOROC data compilations and to provide distinct, citable objects to the researchers that use GEOROC compilations for their work (so-called & #8220 recompiled files& #8221 , a collection of pre-formatted results of the most popular search queries to the GEOROC database are regularly updated and re-published). However, whilst all data submissions by authors are required to fulfill the scope of the GEOROC database, new analytical data need to meet additional quality requirements: the repository enforces a strict template to ensure consistent reporting of all relevant s le and method/analysis metadata. These templates can then be automatically harvested from the repository directly into the GEOROC database, with the added guarantee that new data entries are a) approved by the owners of the datasets, and b) follow a consistent data reporting and quality standard.To encourage user uptake of both the repository and the compilations available in the GEOROC database, DIGIS is working closely with IEDA2 and EarthChem towards developing a common infrastructure for geochemical data. One goal of this collaboration is a single repository submission platform that asserts the same requirements for data and metadata quality of submitted datasets. In addition, DIGIS has also partnered with GFZ Data Services as their trusted domain repository. Finally, through the OneGeochemistry initiative, all three partners are working towards global community-endorsed best practices for geochemical data publication. Ultimately, these efforts will facilitate greater interoperability between globally distributed geochemical data systems, enabling more user-friendly delivery of data publication and compilation services to the research community.

Abstract: As geochemical data enable understanding of the Earth system and help to address critical societal issues the organisation thereof is important. Questions asked about processes affecting our environment and geological past become more complex and interdisciplinary in nature as well as multidimensional. To help answer these questions within the geochemistry research capabilities and data compilations are required to be comprehensive and both human and machine readable. Various international organisations are building infrastructure to capture and distribute geochemical data in a consistent manner adhering to the FAIR principles.& Since May 2021 the OneGeochemistry initiative has officially started efforts towards aligning these organisations& #8217 data frameworks in order to standardise how geochemical data is reported around the globe. In November 2022 the OneGeochemistry initiative applied and was granted to become the OneGeochemistry CODATA Working Group as part of the International Science Councils Committee on Data. The initiative has now also been endorsed by the Geochemical Society, the European Association of Geochemistry and the Working Group has been endorsed by the IUGS Commission on Global Geochemical Baselines. Coordination of the OneGeochemistry initiative is funded through the WorldFAIR project where it is one of the work packages in the larger & #8216 WorldFAIR: Global cooperation on FAIR data policy and practice& #8217 project. A FAIR Implementation Profile analyses of the geochemistry communities of Australia (AusGeochem), USA (EarthChem, AstroMat) and Europe (GEOROC-DIGIS, EPOS-MSL, NFDI4EARTH) resulted in recognition of the need for common vocabularies for geochemistry data reporting as one of the most important actions to undertake towards international geochemistry data interoperability. A task adopted by EarthChem-DIGIS(GEOROC)-GFZ(DataSystems) collaboration and Research Vocabularies Australia.Here we will present an overview of the current OneGeochemistry initiative and its preliminary outcomes with regards to FAIR Implementation Profiles and processes that will help enable geochemical data interoperability between various stakeholders.

Abstract: The majority of geochemical and cosmochemical research is based upon observations and, in particular, upon the acquisition, processing and interpretation of analytical data from physical s les. The exponential increase in volumes and rates of data acquisition over the last century, combined with advances in instruments, analytical methods and an increasing variety of data types analysed, has necessitated the development of new ways of data curation, access and sharing. Together with novel data processing methods, these changes have enabled new scientific insights and are driving innovation in Earth and Planetary Science research. Yet, as approaches to data-intensive research develop and evolve, new challenges emerge. As large and often global data compilations increasingly form the basis for new research studies, institutional and methodological differences in data reporting are proving to be significant hurdles in synthesising data from multiple sources. Consistent data formats and descriptions as well as appropriate information on data quality are becoming crucial to enabling reproducibility and integration of results and fostering confidence for data reuse. Here, we explore the key challenges faced by the geo- and cosmochemistry community and, by drawing comparisons from other communities, recommend possible approaches to overcome them. The first challenge is bringing together the numerous sub-disciplines within our community. One key factor for this convergence will be gaining endorsement from the international geochemical, cosmochemical and analytical societies and associations, journals and institutions. Increased education and outreach, spearheaded by ambassadors recruited from leading scientists across disciplines, will further contribute to raising awareness, and to uniting and mobilising the community. Appropriate incentives, recognition and credit for good data management as well as an improved, user-oriented technical infrastructure will be essential for achieving a cultural change towards an environment in which the effective use and real-time interchange of large datasets is common-place. Finally, the development of best practices for standardised data reporting and exchange, driven by expert working groups, will be a crucial step towards making geo- and cosmochemical data more Findable, Accessible, Interoperable and Reusable by both humans and machines (FAIR).
