Two real use cases of FAIR maturity indicators in the life sciences

Abstract

Data sharing and reuse are crucial to enhance scientific progress and maximize return of investments in science. Although attitudes are increasingly favorable, data reuse remains difficult for lack of infrastructures, standards, and policies. The FAIR (findable, accessible, interoperable, reusable) principles aim to provide recommendations to increase data reuse. Because of the broad interpretation of the FAIR principles, maturity indicators are necessary to determine FAIRness of a dataset. In this work, we propose a reproducible computational workflow to assess data FAIRness in the life sciences. Our implementation follows principles and guidelines recommended by the maturity indicator authoring group and integrates concepts from the literature. In addition, we propose a FAIR balloon plot to summarize and compare dataset FAIRness. We evaluated our method on two real use cases where researchers looked for datasets to answer their scientific questions. We retrieved information from repositories (ArrayExpress and Gene Expression Omnibus), a registry of repositories (re3data.org), and a searchable resource (Google Dataset Search) via application program interface (API) wherever possible. With our analysis, we found that the two datasets met the majority of the criteria defined by the maturity indicators, and we showed areas where improvements can easily be reached. We suggest that use of standard schema for metadata and presence of specific attributes in registries of repositories could increase FAIRness of datasets.

“…As a result, extra care needs to be taken when dataset combination takes place regarding their interoperability to flag sources of potential variability. This also emphasises the need for sufficient metadata implementation [ 87 ] with published datasets to increase their FAIRness score and thus reusability [ 88 ].…”

Structure–activity prediction networks (SAPNets): a step beyond Nano-QSAR for effective implementation of the safe-by-design concept

“…Each experimental study that provides publicly available data, subsequently used for model development, should meet the standards of findability, acces-sibility, interoperability, and reusability (FAIR idea). 21,22 Thus, collecting additional data from various sources and filling the gaps in developed datasets will be possible. Moreover, the presented SAPNet includes a meta-model that links phenol degradation with experimentally measured photoluminescence.…”

The five pillars of computational reproducibility: bioinformatics and beyond

“…In the wake of the Human Genome Project, a number of repositories for specific biological data types were established including Gene Expression Omnibus (GEO), Sequence Read Archive (SRA), European Nucleotide Archive (ENA) and Proteomics Identifications Database (PRIDE) [ 121–123 ]. Although these repositorie suffer issues around interoperability and reusability, they do support data reuse through findability and accessibility [ 124 , 125 ]. The re3data.org registry of data repositories may be useful to find repositories that accepts data from other domains of study like ecology, physiology, molecular simulation, social sciences and computing [ 126 ].…”
