In 2020, EPFL Library conducted a study about Tools and Metadata Standards practice in EPFL School of Life Sciences. By standard, we mean: - terminological resources (vocabularies, terminologies, classifications, thesauri), - formats and data models / schemas, - structured knowledge bases (databases, reference databases, ontologies). And by tools, we mean: - bioinformatics software (i.e. for sequence or molecular structure analysis of proteins and genes) - databases from the Life Sciences field (i.e. genome databases). Our goal was twofold: on the one hand, to gain new knowledge and insights, and on the other hand, to develop a reproducible survey methodology resolutely based on liaison librarian-data librarian collaboration. This report reflects the methods, results and outcomes collected during 3 phases of the study: literature review, survey and interviews.
